I've never seen a job here based in Mauritius; that would be a cool place to work. I'm not sure I could move to a primarily french-speaking African country but it's certainly a beautiful country
Because a primarily french-speaking African country is … ? I am not sure what is your point. Also Mauritius has significant British heritage, they even drive on the “wrong” side of the road.
I don't speak french and don't have any African family/friends. Sorry I didn't mean this as some insightful analysis of the country, just my specific needs. Really interesting job and location.
QUOBYTE | Santa Clara, CA and Berlin, Germany | Full-time | ONSITE | https://www.quobyte.com/
At Quobyte, we are working on the Data Center File System (DCFS), a highly scalable and fault-tolerant software storage system built around a parallel file system core. Customers use Quobyte DCFS for ML and HPC clusters in industry and academia, k8s and OpenStack infrastructures, streaming, web mail, post production, origin and CGI clusters, and as a scalable backend for SaaS products. There are Quobyte DCFS clusters which span thousands of machines and crunch 100s of GB/s!
Under the hood, DCFS is a full-stack storage system, written in Java and C++. The engineering work covers everything from kernel development over our own replicated database system design to distributed algorithms (Paxos!) and performance. In short: lots of real-world challenging and fun problems! We work as a highly efficient engineering team, and do mandatory code reviews, lots of unit and integration testing,
We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.
We're looking for experienced FULL-STACK ENGINEERS who can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Rapid deployment and iteration of experimental software changes across firmware, control software and UI
- Modelling buildings in code and finding the right UI for operators to edit them
We're rapidly scaling up operations and we need experienced, generalist engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
Rectangle | On-site Chicago, or US remote in SF and NY | Full-Time | Salary + Equity
We're looking to hire a dedicated full-stack engineer at Rectangle.

Over the last few months we’ve been investing heavily in building our internal infrastructure to power automation, integration, and visibility across the supply chain. We’re rapidly onboarding new customers and are looking for an engineer who’s excited to build alongside them.
You’ll be working directly with customers, solving real-world problems, and scaling the solutions you build. The products you own end-to-end will coordinate billions of dollars of freight, and unlock real revenue and efficiency for leading tech-enabled logistics companies.
This is a great opportunity for someone who loves to operate 0 → 1 while also being directly involved in shaping our platform strategy as we keep stacking investments we’ve made into our infra layer.
Stack: Typescript, Go, Kafka, SQL, AWS
Email hn [@] rectanglehq.com or submit a POST request with X-Application-Key: FDE-CHALLENGE-01 to challenge.rectanglehq.com and see what happens :)
In my experience chatGPT solves the challenge handily, but it does get to the level of problem that GPT requires my code review for, so either I'm not as good at using chat as I could be or they've found the point at which someone has to prove they can actually do code review to filter; nice.

Jupiter is building a better approach to healthcare for 80 million working age Americans like you and me.

Devyce (YC S22) | UK (remote/onsite/hybrid) | Senior Frontend/Fullstack/Backend Developers | Full Time
We're redesigning the business phone network from the ground up. Starting with mobile apps and a softphone, we're losing the jargon (who cares what an IVR is?) and building features customers actually want. We're getting big enough to start splitting into more focused teams and there's a few different areas that we need; our infra needs a lot of work, we have big dreams for some cool AI agent/pipeline work and there's still a lot of more fundamental phone system specific problems we need to solve.
We try to be flexible around work and don't believe in regular 60-hour weeks. One key aim of our product is to help employees maintain a healthy work/life balance (who wants to be disturbed by business calls on the weekends?) in an age of remote and hybrid work. The founders lead by example, with all of us having worked 4-4.5 day weeks at times in order to spend time with our children.
We're looking for full stack software engineers - doesn't matter if you're much stronger in either the front or back end, but you do need to be able to build all the parts of a feature - there's no "front end team" once the backend is done. There is naturally work that's much more one sided, so you won't be stuck for months on the front end if you prefer the backend, but we're still a small startup so we expect you to get stuck in and help out where you can!
You'll need to visit our London office roughly once a month.

You'll be responsible for implementing AI-First development methodologies, integrating sophisticated AI tools into our software pipeline, and rapidly building MVP prototypes that demonstrate innovative solutions. This role offers the opportunity to work at the cutting edge of AI-integrated development while delivering high-impact prototypes in a fast-paced, iterative environment. The ideal candidate thrives in rapid prototyping environments, has hands-on experience with AI tool integration, and enjoys the challenge of quickly turning concepts into working demonstrations for stakeholder validation. Candidates should also have know and work with AI code generation tools (Claude Code, Cursor, Copilot, etc).
If this sounds like something you'd be interested in please apply!
At Strum, we're reimagining technology that powers global supply chain using a fresh AI-first approach.

This is for a team that I'm working closely with and helping grow. We're hiring for somebody with a hybrid SWE and Security background to help scale up the team.
It's currently one engineer who's got a ton on his plate, so the ideal person for this role is somebody who's interested in learning, digging in deep to fix issues (especially shipping PRs), and helping shape the future roadmap of the team. It is not an analyst role.
The role is primarily targeted at mid-career folks with a few years of experience (2+ years minimum). Those that are Senior/Staff level folks, especially those with a strong SWE background that are curious about security, are encouraged to apply if this role resonates strongly. (I personally transitioned from SWE -> ProdSec, years ago, and several other folks on the broader Security team have non-Security backgrounds too.)
Feel free to apply there, email me with you resume (on my profile), or add me on LinkedIn[0]. I'll try my best to answer questions and reply to everybody, but sometimes there is so much inbound that it isn't possible. Thanks!

Erdos Miller | Data Wrangler (Part-time → Full-time growth) | Remote (US preferred, flexible otherwise)
We build Measurement While Drilling (MWD) equipment — and we love it. That passion helped us capture the majority of the North American oil & gas market, and now it’s fueling our geothermal innovation, building underground navigation systems for the next generation of clean energy.
We’re now looking for a Data Wrangler to help us make smarter, faster decisions with our data. This role blends data engineering and data science: wrangling quirky file formats, structuring messy datasets, and turning it all into live tools that guide company strategy. Starts part-time with the opportunity to grow into a full-time, career-defining role.
What you’ll do
Partner with the CEO + stakeholders to translate business needs into pipelines, dashboards, and tools.
Build ETL pipelines, write parsers for proprietary formats, and maintain relational databases (PostgreSQL, MySQL).
Create interactive dashboards/apps with Dash, Streamlit, or similar (we avoid Tableau/Excel hell).
Deliver insights via live web apps where data isn’t static — it’s explorable.
Tech we use
Python, SQL (PostgreSQL/MySQL), S3, modal.com.
Bonus: React/web dev experience to shape customer-facing real-time tools.
Why you’ll like it here
You’ll own projects end-to-end, avoid over-engineering (no Kubernetes, no Airflow — just the right tools), and directly influence decisions. As our company and data needs grow, so does your role.
If this sounds fun, email ken@erdosmiller.com with your background and what excites you about wrangling data.
I worked here for a few months several years ago - justifiably let go for non-performance, it was a strange time in my life and I had a lot of distractions, it was an amicable separation.
While they expect consistent high performance, the bar is reasonable and the hours can be a bit long for some but aren't insane. Everyone at the company is smart and driven. Both founders are highly technical, very passionate, genuinely business-savvy, and great with customers. Abe Erdos is borderline polymath genius - topics like wavelet decomposition are relatively pedestrian to Abe, and he seems equally comfortable in mechanical engineering, electrical engineering, and computer science (all of which are critical to this business). Abe's also a good listener, it's easy to underestimate him and difficult to overestimate him. Ken Miller has more energy than anyone I've ever seen, a very broad and reasonably deep understanding of pretty much everything, and generally has strong opinions - if you want to challenge his roadmap, it's best to stay one step ahead of him and show rather than tell.
It's a fairly mature product, but the business still moves at a much faster pace than the rest of their industry and they constantly innovate. They stay on top of technological changes; they rarely take more than a year to adopt something new that is applicable to their products. Has the feeling of a "very stable start-up". They truly own both the hardware and data end-to-end, which is very helpful. They have expertise and ownership of every level of abstraction - they'll build Helmholtz coils in-house to calibrate instruments on custom PCBs designed and soldered in-house, while managing distributed systems from edge to datacenter, run their products at customer sites, maintain personal relationships with their customers and employees, and deal with legal action directly themselves.
If you're interested - understand that what might take 1-3 months at a large corporation is often accomplished in a few days to a week here. Working, manipulable demos are appreciated over presentations. If discussion hits a wall where it's impossible to know whether going direction A or B is correct, they will simply pick one direction to explore rather than deliberate further and they'll use that exploration to gain more information, open to backtracking and going the other direction, but only if it's profitable to do so.
Every person there has built a lot, either product or business. They focus on building things that don't suck, and they don't have much patience for things that do. So generally you won't have to worry about being forced to use crappy tools that make you miserable. There are a LOT of different personalities in the company, all strong in their own ways (some quiet, some loud, some blunt) so it's probably best if you are the type of person who can work with a variety of personalities - but this isn't a euphemism to indicate toxic personalities - if you're high energy and passionate you'll feel at home, sometimes opinions can fly fast and hot but the best results are gained by communicating clearly and decisively, not emotionally. Some employees are quieter and it's often best to be quieter with them and listen more. Keeping an emotional buffer/distance between you and work decisions made by your colleagues/bosses will help a lot. If there's loud direct criticism, it's about the work - not the person.
Most of their employees are on-location, but they integrate remote workers well enough - quite a few excellent employees work remotely and communication is good. You might miss some in-person chatter but you won't be completely blindsided (at least not much more than anyone else in a company that makes decisions faster than you can complete a story point).
When I was there, compensation was definitely reasonable - I was comfortable. It's an MCOL, but we had a competent developer in NY who stayed with the company through the tech boom years.
Thank you for writing that. It may be the most remarkable and insightful recommendation and advisory I have ever seen. And from someone who was let go, no less.

Third Iron | Senior Full-Stack Software Developer | REMOTE (US)
Do you want to develop software that helps scientists, doctors, and historians discover breakthroughs? Join our small, fully-distributed software development team to help connect scholars of all disciplines with peer-reviewed journal articles.
Our company has been remote-first since we began in 2011. You’ll join a team with plenty of experience putting into practice what works well remotely, and avoiding what doesn’t.
Third Iron has never taken VC money, and we’ve never had layoffs. Our approach to hiring and selling our products helps us feel confident that this pattern will continue far into the future.
Third Iron software is used by researchers at over 1,500 libraries, including universities, hospitals, corporations, and government agencies located in over 35 countries.
In a refreshing change from advertising-dependent tech companies and those who sell user data, we instead have a business-to-business model. We sell our subscription-based services to libraries, and anyone affiliated with one of these libraries can use our software. We do not sell user data. Our focus is on building the best software to enable research that changes the world.
We’re looking for a developer interested in full-stack work, since we have a variety of upcoming initiatives, some being mostly front-end, some being mostly back-end, and some a balance of the two.
The front-end of our stack primarily consists of JavaScript, using EmberJS for two major projects, and React for two others. Our backend is written in NodeJS, and features data storage using PostgreSQL, Elasticsearch, and CouchDB, and hosting primarily on AWS and HEroku.
WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re hiring on the backend to help solve one of the hardest problems in data engineering: building a production knowledge graph from millions of fragmented, inconsistent Chinese corporate records where traditional approaches break down. Our PySpark/EMR/Airflow pipeline is just the foundation. The real challenges are in entity resolution across transliterated names and obfuscated ownership structures, bipartite matching algorithms and inferring relationships. We build our product on top of that with a Django/FastAPI/React stack to help our users access that knowledge graph to analyze and investigate any risks they should be aware of.
If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.
Happy to answer any questions - you can reach out to me here or at leo.green@wirescreen.ai - I'm a recruiter with WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.
At Imubit, we’re not just optimizing industrial processes - we’re redefining how entire industries operate.

We're seeking an experienced software developer to work on novel problems in data storage on Ethereum. We're launching a new network that uses Optimism L3s.
You'll develop smart contracts, design and maintain infrastructure built for resilience, throughput and decentralization (Optimism, Kubernetes, IPFS) and manage deployment pipelines (argo-cd, restate).
Key Requirements:
- Experience with, and interest in keeping up with, the Ethereum ecosystem
- Knowledge of the architecture and trade-offs of optimistic rollups
- Good understanding of Solidity for smart contract development
- DevOps experience with CI/CD, containerization, and Kubernetes

Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)
In education, we have always traded off scale and quality. In a 30-student math class, half of kids are ready to accelerate while half are still working on their foundational skills, but teachers cannot be in 30 places at once, giving each student one-on-one support.
Until now. Imagine 30 teachers in every classroom—that's how Goblins feels. Students draw math on any device, and our AI figures out the "why" behind their confusion, giving instant feedback and building conceptual foundations. (Preview: https://youtu.be/SH9UomzBMUs)
Goblins launched to school districts in the spring of 2025. Since then we've built a waitlist of thousands of teachers and sold Goblins to districts across the US (we'll hit 100k+ paid students this year!). We are in the unique position of having a product that is both highly differentiated and demanded :)
Technical problems we've worked on in the past:
→ Building knowledge graphs that adapt to student performance in real-time, routing them to the optimal next problem they should solve to maximize learning and engagement.
→ Extending our handwriting recognition from digital canvas to real paper through Chromebook cameras (think real-time OCR on math equations through low-quality webcams with poor lighting and limited CPU).
→ Creating interactive mathematical lessons (think 3blue1brown, but conversational) that remediate student misconceptions.
You'll be joining founding team members Sawyer (CEO, former Head of Design at X1 [acquired by Robinhood] and math teacher) and Alp (CTO, ex-Stripe and Amazon), plus two other exceptional founding engineers.
We move fast, care deeply about craft, and obsess over delighting users. If you're interested, email alp@goblinsapp.com :)

Testimonial from a team member: “Long story, but I worked there for maybe 6ish months part time a while back. They offered me full time, but I ended up going to a startup because I wanted to learn some specific technologies + up my skills in Data Science. That job was definitely good for some people, but it wasn’t as remote as they advertised it (had me fly in a lot), and the team was somewhat difficult to work with ;) I ended up starting my own consulting and at the same time CourtDrive reached back out to me (perfect timing). Point I was trying to make was that I went back to work with them because they were so nice to work with. Not super demanding and very open to listening to ideas/suggestions - just a pleasant environment.”

Chef Robotics | Several Opportunities | Full-time | San Francisco, CA (in office)
At Chef Robotics, we’re on a mission to accelerate the advent of intelligent machines in the physical world. Our focus is food, a $300B+ labor market in the US alone, and we’re building AI-powered robots to help food companies scale and automate repetitive tasks. Backed by leading investors like Kleiner Perkins, Construct Capital, Bloomberg Beta, and Promus Ventures, we’re building a team of world-class engineers, roboticists, and business leaders to transform one of the world's largest industries.
About us:
Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.
The problem we’re solving:
Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.
We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.
Why it matters:
This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.
The role:
We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions

Rotabull | Senior Software Engineer | Full Time | Hybrid 3x / week | NYC
Rotabull is building a next-generation platform for buying and selling aircraft parts, to bring online the $75 billion that airlines spend on parts and repairs each year. Our customers are aircraft parts suppliers around the world, depending on our systems to run their day-to-day businesses.
We're expanding our NYC-based team with a few hires over the next year -- if working with a small, bootstrapped team in a legacy industry with lots of opportunity appeals to you, please see https://app.dover.com/jobs/rotabull for more information or to apply.
Actively AI| Multiple Roles | In office in NYC | Salary + Equity
What Cursor has done to revolutionize coding, we are looking to do for revenue. Every large company spends 40-50 cents of every dollar they earn on sales & marketing, and it’s very inefficient because data lives in so many different systems, sales reps are stretched thin doing manual work, and products are rapidly evolving.
It’s why we are building the agent and intelligence framework for enterprise scale GTM that guides every sales motion across the funnel — from SDR outreach to AE deal strategy to cross-sell and expansion. It’s an intelligence layer that sits on top of every sales tool and with external browsing that is then customized to your specific products & GTM motions.
It’s a massive technical challenge:
- Intelligence at scale: modeling millions of accounts, real-time signals, and contextual history into per-account reasoning agents.
- AI Agents & Chat: designing systems across “push” (recommendations) and “pull” (interactive assistants), with extensible skills customers can train themselves.
- Data & Infrastructure: creating a new framework for real-time, per-customer agents that simplifies pipelines, scales efficiently, and cuts costs (we’ve already cut cost per account by 50% through smarter eval-driven approaches).
- Wall-to-wall product: from self-serve UI to Slack integrations, from predictive models to generative copilots — we’re building an AI operating layer for GTM.
Why Join Engineering at Actively:
- Customer-driven impact: engineers directly go onsite and spend time with customers, deploying agents that reshape workflows at companies like Samsara and Justworks.
- Category creation: there’s a huge opportunity to build the pre-dominant AI company for GTM with a massive TAM
- Cutting-edge AI: opportunity to push the frontier of reasoning agents, eval-driven development, and scalable intelligence.
- High-caliber peers: we’re ex-Instacart, Scale AI, Stanford AI researchers, and operators who’ve built at scale before.

YC is also knee-deep in applying AI tools and techniques across all of our product surface areas, and investor-focused work is no exception. We’re happy to share more when we chat in person.
We also want to work with people who love building full stack web apps. While our stack is Rails, React and Postgres, mostly we’re just a bunch of pragmatic builders who are excited about shipping and having impact.

Property Meld | Senior Software Engineer | Full-time | Remote (US & Canada) or Rapid City, SD
Looking for something more meaningful? How about the opportunity to have a direct impact on the property maintenance experience for hundreds of thousands of residents?
Welcome to the future of property maintenance. Property Meld’s vision is to radically improve how the property management industry handles property maintenance. If you’ve ever had a maintenance issue at your housing rental, you know how much of a pain it can be to get it fixed quickly and reliably. It doesn't have to be this way. We're rethinking the entire property maintenance experience from the ground up with two things in mind - first, driving the cost of doing maintenance to the absolute minimum, and second, providing an experience to residents and property owners that makes them want to stay with their property manager. If you are excited about turning something that has historically been a negative experience (maintenance) into a positive experience, we'd love to talk with you.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs, and our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS or AI company, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.
Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

Modeling human societies and interaction dynamics is extraordinarily challenging yet potentially transformative—solving it could unlock breakthrough applications in simulation, prediction, and coordination. I believe multi-agent LLM systems with hive-mind architectures are uniquely suited for this because they excel at the very thing that makes human behavior hard to model: probabilistic, unpredictable dynamics.
As an open source contributor to claude-flow and claude-swarm, I've worked on systems where specialized agents (Queen orchestrator, Workers, Scouts, Guardians, Architects) collaborate through:
- Task orchestration with decomposition, distribution, and progress aggregation
- Consensus protocols with voting and tie-breaking for strategic decisions
- Shared memory enabling collective learning and pattern recognition
- Real-time coordination with auto-scaling, load balancing, and fault tolerance
- Self-healing mechanisms that rebalance and recover from failures
This hive-mind approach demonstrates how agent collectives can achieve what isolated agents cannot: parallel problem-solving, emergent intelligence, and robust execution at scale. The probabilistic nature of LLMs—often seen as a limitation—becomes an asset when simulating the inherent unpredictability of human social systems.
I'm eager to contribute to teams working on agent societies, emergence, and collective intelligence. GitHub: https://github.com/Tar-ive

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
We're looking for remote junior engineers that have 0-3 years of professional experience in software, and 5+ years of curiosity exploring computers, programming, and technical hobby projects. This is an open-ended entry role with mentorship and diverse opportunities to work on all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more. To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.
Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule.
We're hiring generalist software engineers to work on web applications, data mining, machine learning/data science, data transformation/ETL, data modeling, database scaling, infrastructure, devops, and more. We'll cater the role to whatever subset of these areas match your interests.
Beneficial experience includes PostgreSQL, Python, Rust, Linux, TypeScript, Nix, frontend/backend web development, and data mining.
I’m Kiran, Chief of Staff (CoS) at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
Fullstory provides privacy-preserving session replay and analytics for websites and mobile apps. Our session replays are nothing short of magical - they look almost like a video of the user's screen (with private details redacted) - and the combination with analytics creates eye-opening insights.
We have several roles open in engineering & product. The backend roles are going to be working with Go (golang), gRPC, Solr, BigQuery/BigTable, Kubernetes (K8S/GKE), and more on Google Cloud Platform (GCP), and then the fullstack roles add in TypeScript & React for the frontend.
We also have a few more roles open in the US & UK in sales, finance, and customer support - see https://www.fullstory.com/careers/ for the full list and some general info.
For US roles, in addition to the listed pay ranges, you can expect regular raises & bonuses, equity, and benefits including: health insurance, 401k matching (Vanguard), annual learning stipend, unlimited PTO, and more. I take about 5 weeks vacation a year, in addition to ~3 weeks worth of company holidays (federal holidays + the week of Christmas to New Years.)
You also get a 5-week sabbatical after 5 years of employment - I took mine at the end of last year, and it was fantastic.
To apply, please submit your info on the website, and our recruiting team will get in touch with you. If you have questions, feel free to reply here or contact me directly. (I'm an engineer on the iOS team, but I'll do my best to answer questions.)
Phrasing.app | Co-founder | EU Remote | Elixir | Clojure
Phrasing is a language learning app built by a polyglot, for polyglots. It was designed to be language agnostic, and currently fully supports over 80 languages. It brings a beautiful, simple, and addictive [1] learning experience to languages big and small, and helps users learn 2-10x more in the same amount of time [2].
The tech stack is a ClojureScript PWA on the front end, and an Elixir umbrella application on the backend. The data processing happens in Broadway pipelines, and are horizontally scalable with FLAME. All of the data is stored in Postgres, and most of the communication between the client and server happens with a custom local-second sync engine à la Linear.app.
The company is bootstrapped and bespoke. There’s no investors, there’s no AI generated code, no shadcdn UIs. I miss the days of the early internet, and acutely feel the mass enshittification of the web. I’m really trying to do something different with the experience as well as the business, all in hopes to bring back a little bit of that wonder that was so prevalent in the days of the early internet.
The app is all working, the experience is great, and the onboarding was just finished. I’ve been using the app now to successfully learn 18 languages [3] and it’s truly a joy to use. Just finishing up the new site [4] after feedback from our last launch and getting ready for more launches [5]. The new video has been getting some pretty rave reviews and is a good gentle introduction to the app [6]
For me, this app is a dream app. This tech stack is a dream tech stack. This company is a dream company. It’s hard to believe I’m the only one these would all be true for.
I’m looking for someone who believes in the product, mission [6], and tech to come in and help me turn this functioning application into something truly great. No experience is required — just a dedication for your craft, and the willingness to take a chance in something you believe in.
If you feel that this post was written for you, please write me a well written personalized CV to hn at phrasing dot app. Low effort applications will not receive a response regardless of your CV.
> If an admin / potential applicant is reading, these guys have been "hiring" since last summer.
Conspiracies about fake hiring are getting really tiring. I don't know about Beacon AI, but we too have been hiring since last summer. Heck even longer than that. We are a small company and our headcount has not changed much in the past year. We hire some people and some people left.
FAANG are still hiring while their headcount overall has actually gone down in the recent past.
But it's not that difficult to implement that functionality, if company posts more than 3 times a year you can ping them if they really are hiring.
We are not asking for policing but every publicly available forum is swamped with ghost jobs and consultancies which are basically farming resumes and personal data. It makes the internet barely usable. These are not good faith actors.
I have to disagree there—this is a complicated domain and I'm afraid it would be quite difficult to get right. For example, I'm sure there are quite a few legit companies posting more than 3 times a year. Excluding them wouldn't be a good strategy; they might well be some of the best places to get hired.
You're certainly correct that there are bad actors, on both sides of the hiring transaction—that is, there are fake jobs and also fake job applicants. Unfortunately it is a hard problem to solve, and we have no particular expertise in it.
Zoca | AI Engineer | Full-time | Bangalore (In-office)
I'm Shambhav, CTO & co-founder at Zoca. I'm building a team to push the boundaries of what's possible with AI.
So far, we've built a platform from Bangalore that has outperformed every competitor in our space — small businesses happily pay us 10x our competitors' price because our agents actually work. These agents work like real business partners, generate leads, do followups, book appointments, manage reviews and more. We're already powering growth for over a thousand businesses.
In the next 12 months, we're going to scale this to tens of thousands, while making the agents smarter, more reliable, and capable of things people think aren't possible today. We'll be working on technical challenges like multi-channel conversations, browser automation at scale, retrieval pipelines, and real-time monitoring/eval loops.
I need AI Engineers who want to build like founders — not paper over things in a research repo, but ship production systems that touch real users. Strong TS/Python skills, a builder's mindset, and a track record of actually building (agents, GSoC projects, or similar) is what I'm looking for.
If this excites you, send me an email at shambhav@zoca.com with your working demos or GitHub profile. Show me what you've hacked on.

The website probably hasn't been updated to reflect the effect of Trump's recent $100K fee for H1B visas.
I would believe that current statement over the website in this case.
International shops can easily do transfer visas such as L1A/L1B. O-1 visas aren't hard to obtain either.
The posting date was two days ago.
And not sure if you’re aware, but there’s like a few dozen visa categories that allow immigrants to work. The hype around H1B is entertaining though!
Standard verbiage on job listings is often not immediately updated in systems for posting jobs.
My expectation of what is true doesn't change much.

Multiply | Python + SQL Software Engineer | On-site | Mauritius
We build repricing software that keeps online sellers on top of their competition on 130+ marketplaces.
Stack: Python, Postgres, FastAPI, SQLAlchemy.
Our office is beautifully located in Mauritius. We sponsor visas and handle all relocation/immigration.
Apply: jobs@multiply.cloud
I've never seen a job here based in Mauritius; that would be a cool place to work. I'm not sure I could move to a primarily french-speaking African country but it's certainly a beautiful country
Because a primarily french-speaking African country is … ? I am not sure what is your point. Also Mauritius has significant British heritage, they even drive on the “wrong” side of the road.
I've interacted with dev teams in Mauritius. The dev culture was more Indian than it was anything else.
It's not all that that distant from India actually, if you disregard the open water between them. Wikipedia has Mauritius as ethnically "67% Indian"
I don't speak french and don't have any African family/friends. Sorry I didn't mean this as some insightful analysis of the country, just my specific needs. Really interesting job and location.

In my experience chatGPT solves the challenge handily, but it does get to the level of problem that GPT requires my code review for, so either I'm not as good at using chat as I could be or they've found the point at which someone has to prove they can actually do code review to filter; nice.
Shhh don't spoil the first filter! ;) Fun set of challenges though, they totally nerd-sniped me.

Tandem Health | Senior/Staff Software Engineers | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)
We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)
Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

Phosphor | NYC/Remote | Full Time | Founding Engineer | $150-225k + Equity
Phosphor builds recursively self-improving systems (via malleable software and natural language interfaces) to enable the efficient development and financing of the physical world (infrastructure, energy, real estate).
Our product is built around a powerful object model which combines document editors with proprietary programming languages for financial modeling, computable contracts, etc, in order to build one of the more unique RLHF feedback loops that we've seen to date.
A primary technical bet is that if we can productize version control properly, we can capture annotated "diffs" of user information with user-validated annotations. By doing so, we create path-dependence, which enables us to specify system-level goals for agents to solve for.
Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.
We're venture-backed by one of the best deeptech funds in the market and are hiring for roles spanning product engineers, CRDT wizards, and compiler/calculation engine leads.

Devyce (YC S22) | UK (remote/onsite/hybrid) | Senior Frontend/Fullstack/Backend Developers | Full Time We're redesigning the business phone network from the ground up. Starting with mobile apps and a softphone, we're losing the jargon (who cares what an IVR is?) and building features customers actually want. We're getting big enough to start splitting into more focused teams and there's a few different areas that we need; our infra needs a lot of work, we have big dreams for some cool AI agent/pipeline work and there's still a lot of more fundamental phone system specific problems we need to solve.
We try to be flexible around work and don't believe in regular 60-hour weeks. One key aim of our product is to help employees maintain a healthy work/life balance (who wants to be disturbed by business calls on the weekends?) in an age of remote and hybrid work. The founders lead by example, with all of us having worked 4-4.5 day weeks at times in order to spend time with our children.
We're looking for full stack software engineers - doesn't matter if you're much stronger in either the front or back end, but you do need to be able to build all the parts of a feature - there's no "front end team" once the backend is done. There is naturally work that's much more one sided, so you won't be stuck for months on the front end if you prefer the backend, but we're still a small startup so we expect you to get stuck in and help out where you can!
You'll need to visit our London office roughly once a month.

Strum AI | Founding/Lead Engineer | https://www.linkedin.com/company/strum-ai/

We’re on our journey to democratizing supply chain technology. As our first engineer, you’ll be working with the founders (former Supply chain/tech directors at Amazon who have built key components of Amazon's supply chain) to develop the core product from the grounds up (involves application of LLMs, deep learning, and optimization). If you have mid to senior level experience in software development, have built SaaS applications, understand ML-Engineering, and love building 0->1 products, we would love to talk to you. Please reach out to us at: careers@strum-ai.com.

ToucanTix | Senior Ruby on Rails Developer | REMOTE (EU/US timezones preferred)
Your code will run the gates at zoos and theme parks across Germany and the USA. When families scan tickets, when capacity limits kick in based on visitors and available resources (staff, equipment, facilities), when dynamic pricing adjusts for weather - that's our Rails app making real-time decisions for thousands of visitors daily.
We're 5 engineers at ToucanTix (sister company Combase has 80+). You'd have serious ownership and architectural influence from day one.
Technical challenges that actually matter:
Multi-tenant architecture supporting 100+ venues with wildly different business logic. Offline-first POS that syncs flawlessly. Complex pricing rules (weather + season + capacity + customer type) that need to stay performant. Hardware integrations with access control and payment systems.
Stack: Rails 7+ API with GraphQL (graphql-ruby), PostgreSQL doing serious heavy lifting with multi-tenant architecture, Redis for speed-critical stuff, SvelteKit frontend (if you're full-stack curious), Google Cloud infrastructure (Cloudtasker, Cloud Storage), RSpec/Capybara keeping everything bulletproof
You: 5+ years Rails. Strong at PostgreSQL optimization. Have architected systems for performance and scale. Comfortable owning technical decisions.
Us: Real ownership. No layers of management. Async-first remote culture. Profitable company, not burning VC cash. Your work has physical impact - people literally can't enter the attraction if your code breaks.
Full details: https://www.toucantix.com/careers/senior-ruby-on-rails-devel...
Apply: jobs@toucantix.com - Send CV + one technical challenge you're proud of solving. Put in subject line.

Scale AI | Product Security Engineer | TypeScript, Node, Python, AWS | Full-time | Hybrid in San Francisco, CA or NYC or Remote
This is for a team that I'm working closely with and helping grow. We're hiring for somebody with a hybrid SWE and Security background to help scale up the team.
It's currently one engineer who's got a ton on his plate, so the ideal person for this role is somebody who's interested in learning, digging in deep to fix issues (especially shipping PRs), and helping shape the future roadmap of the team. It is not an analyst role.
The role is primarily targeted at mid-career folks with a few years of experience (2+ years minimum). Those that are Senior/Staff level folks, especially those with a strong SWE background that are curious about security, are encouraged to apply if this role resonates strongly. (I personally transitioned from SWE -> ProdSec, years ago, and several other folks on the broader Security team have non-Security backgrounds too.)
Here is the role: https://scale.com/careers/4602047005
Feel free to apply there, email me with you resume (on my profile), or add me on LinkedIn[0]. I'll try my best to answer questions and reply to everybody, but sometimes there is so much inbound that it isn't possible. Thanks!

Erdos Miller | Data Wrangler (Part-time → Full-time growth) | Remote (US preferred, flexible otherwise)
We build Measurement While Drilling (MWD) equipment — and we love it. That passion helped us capture the majority of the North American oil & gas market, and now it’s fueling our geothermal innovation, building underground navigation systems for the next generation of clean energy.
We’re now looking for a Data Wrangler to help us make smarter, faster decisions with our data. This role blends data engineering and data science: wrangling quirky file formats, structuring messy datasets, and turning it all into live tools that guide company strategy. Starts part-time with the opportunity to grow into a full-time, career-defining role. What you’ll do
Partner with the CEO + stakeholders to translate business needs into pipelines, dashboards, and tools. Build ETL pipelines, write parsers for proprietary formats, and maintain relational databases (PostgreSQL, MySQL). Create interactive dashboards/apps with Dash, Streamlit, or similar (we avoid Tableau/Excel hell). Deliver insights via live web apps where data isn’t static — it’s explorable. Tech we use Python, SQL (PostgreSQL/MySQL), S3, modal.com. Bonus: React/web dev experience to shape customer-facing real-time tools. Why you’ll like it here You’ll own projects end-to-end, avoid over-engineering (no Kubernetes, no Airflow — just the right tools), and directly influence decisions. As our company and data needs grow, so does your role. If this sounds fun, email ken@erdosmiller.com with your background and what excites you about wrangling data.
I worked here for a few months several years ago - justifiably let go for non-performance, it was a strange time in my life and I had a lot of distractions, it was an amicable separation.
While they expect consistent high performance, the bar is reasonable and the hours can be a bit long for some but aren't insane. Everyone at the company is smart and driven. Both founders are highly technical, very passionate, genuinely business-savvy, and great with customers. Abe Erdos is borderline polymath genius - topics like wavelet decomposition are relatively pedestrian to Abe, and he seems equally comfortable in mechanical engineering, electrical engineering, and computer science (all of which are critical to this business). Abe's also a good listener, it's easy to underestimate him and difficult to overestimate him. Ken Miller has more energy than anyone I've ever seen, a very broad and reasonably deep understanding of pretty much everything, and generally has strong opinions - if you want to challenge his roadmap, it's best to stay one step ahead of him and show rather than tell.
It's a fairly mature product, but the business still moves at a much faster pace than the rest of their industry and they constantly innovate. They stay on top of technological changes; they rarely take more than a year to adopt something new that is applicable to their products. Has the feeling of a "very stable start-up". They truly own both the hardware and data end-to-end, which is very helpful. They have expertise and ownership of every level of abstraction - they'll build Helmholtz coils in-house to calibrate instruments on custom PCBs designed and soldered in-house, while managing distributed systems from edge to datacenter, run their products at customer sites, maintain personal relationships with their customers and employees, and deal with legal action directly themselves.
If you're interested - understand that what might take 1-3 months at a large corporation is often accomplished in a few days to a week here. Working, manipulable demos are appreciated over presentations. If discussion hits a wall where it's impossible to know whether going direction A or B is correct, they will simply pick one direction to explore rather than deliberate further and they'll use that exploration to gain more information, open to backtracking and going the other direction, but only if it's profitable to do so.
Every person there has built a lot, either product or business. They focus on building things that don't suck, and they don't have much patience for things that do. So generally you won't have to worry about being forced to use crappy tools that make you miserable. There are a LOT of different personalities in the company, all strong in their own ways (some quiet, some loud, some blunt) so it's probably best if you are the type of person who can work with a variety of personalities - but this isn't a euphemism to indicate toxic personalities - if you're high energy and passionate you'll feel at home, sometimes opinions can fly fast and hot but the best results are gained by communicating clearly and decisively, not emotionally. Some employees are quieter and it's often best to be quieter with them and listen more. Keeping an emotional buffer/distance between you and work decisions made by your colleagues/bosses will help a lot. If there's loud direct criticism, it's about the work - not the person.
Most of their employees are on-location, but they integrate remote workers well enough - quite a few excellent employees work remotely and communication is good. You might miss some in-person chatter but you won't be completely blindsided (at least not much more than anyone else in a company that makes decisions faster than you can complete a story point).
When I was there, compensation was definitely reasonable - I was comfortable. It's an MCOL, but we had a competent developer in NY who stayed with the company through the tech boom years.
Thank you for writing that. It may be the most remarkable and insightful recommendation and advisory I have ever seen. And from someone who was let go, no less.

Our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications.

Third Iron | Senior Full-Stack Software Developer | REMOTE (US)
Do you want to develop software that helps scientists, doctors, and historians discover breakthroughs? Join our small, fully-distributed software development team to help connect scholars of all disciplines with peer-reviewed journal articles.
Our company has been remote-first since we began in 2011. You’ll join a team with plenty of experience putting into practice what works well remotely, and avoiding what doesn’t. Third Iron has never taken VC money, and we’ve never had layoffs. Our approach to hiring and selling our products helps us feel confident that this pattern will continue far into the future.
Third Iron software is used by researchers at over 1,500 libraries, including universities, hospitals, corporations, and government agencies located in over 35 countries.
In a refreshing change from advertising-dependent tech companies and those who sell user data, we instead have a business-to-business model. We sell our subscription-based services to libraries, and anyone affiliated with one of these libraries can use our software. We do not sell user data. Our focus is on building the best software to enable research that changes the world.
We’re looking for a developer interested in full-stack work, since we have a variety of upcoming initiatives, some being mostly front-end, some being mostly back-end, and some a balance of the two.
The front-end of our stack primarily consists of JavaScript, using EmberJS for two major projects, and React for two others. Our backend is written in NodeJS, and features data storage using PostgreSQL, Elasticsearch, and CouchDB, and hosting primarily on AWS and HEroku.
If you’re interested in this fully remote position, we're interested to chat with you! Please email careers@thirdiron.com or apply at https://thirdiron.applytojob.com/apply/McK2VdxTuX/Senior-Ful...
WireScreen (Series A) | Senior Software Engineer | NYC - hybrid | Full-time | $165k-$200k base + equity | https://jobs.ashbyhq.com/wirescreen/158fd72f-fc2f-47a3-bdb5-...
WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re hiring on the backend to help solve one of the hardest problems in data engineering: building a production knowledge graph from millions of fragmented, inconsistent Chinese corporate records where traditional approaches break down. Our PySpark/EMR/Airflow pipeline is just the foundation. The real challenges are in entity resolution across transliterated names and obfuscated ownership structures, bipartite matching algorithms and inferring relationships. We build our product on top of that with a Django/FastAPI/React stack to help our users access that knowledge graph to analyze and investigate any risks they should be aware of.
If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.
Apply here: https://jobs.ashbyhq.com/wirescreen/158fd72f-fc2f-47a3-bdb5-...
Happy to answer any questions - you can reach out to me here or at leo.green@wirescreen.ai - I'm a recruiter with WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.

Ever wonder how millions of highlights and game-film videos get processed and delivered to teams around the globe? It happens on the Core Video team at Hudl, and we're looking for a Senior Software Engineer to join!
Every day Hudl solves challenges around our video processing pipeline that handles thousands of concurrent videos while prioritizing cost-efficiency, scalability, and exceptional video quality. We work on problems at a scale that few other companies can offer.
Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)
In education, we have always traded off scale and quality. In a 30-student math class, half of kids are ready to accelerate while half are still working on their foundational skills, but teachers cannot be in 30 places at once, giving each student one-on-one support.
Until now. Imagine 30 teachers in every classroom—that's how Goblins feels. Students draw math on any device, and our AI figures out the "why" behind their confusion, giving instant feedback and building conceptual foundations. (Preview: https://youtu.be/SH9UomzBMUs)
Goblins launched to school districts in the spring of 2025. Since then we've built a waitlist of thousands of teachers and sold Goblins to districts across the US (we'll hit 100k+ paid students this year!). We are in the unique position of having a product that is both highly differentiated and demanded :)
Technical problems we've worked on in the past:
→ Building knowledge graphs that adapt to student performance in real-time, routing them to the optimal next problem they should solve to maximize learning and engagement.
→ Extending our handwriting recognition from digital canvas to real paper through Chromebook cameras (think real-time OCR on math equations through low-quality webcams with poor lighting and limited CPU).
→ Creating interactive mathematical lessons (think 3blue1brown, but conversational) that remediate student misconceptions.
You'll be joining founding team members Sawyer (CEO, former Head of Design at X1 [acquired by Robinhood] and math teacher) and Alp (CTO, ex-Stripe and Amazon), plus two other exceptional founding engineers.
We move fast, care deeply about craft, and obsess over delighting users. If you're interested, email alp@goblinsapp.com :)

At CourtDrive.com, we are building an AI Docketing Assistant that enables law firms and other power courthouse website users to become more efficient by automating daily tasks. We’re based in Los Angeles but have a remote team worldwide (Canada, Europe, Armenia to name a few). Your role as Principal AI Engineer will be to lead CourtDrive's AI strategy through model evaluation, fine-tuning, and data collection. You'll work alongside our engineering team to bring AI features from concept to production, while elevating the team's understanding of language model capabilities and best practices. Your expertise will be crucial in determining how we can best leverage AI to enhance our solution.
This role offers a unique opportunity to apply deep language model experience in a product focused on transforming how law firms practice the business of law.
Testimonial from a team member: “Long story, but I worked there for maybe 6ish months part time a while back. They offered me full time, but I ended up going to a startup because I wanted to learn some specific technologies + up my skills in Data Science. That job was definitely good for some people, but it wasn’t as remote as they advertised it (had me fly in a lot), and the team was somewhat difficult to work with ;) I ended up starting my own consulting and at the same time CourtDrive reached back out to me (perfect timing). Point I was trying to make was that I went back to work with them because they were so nice to work with. Not super demanding and very open to listening to ideas/suggestions - just a pleasant environment.”

Absinthe Labs | Full-Stack Engineer | REMOTE / NYC Hybrid | Full-Time
About us: Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.
The problem we’re solving: Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.
We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.
Why it matters: This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.
The role: We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions
Get involved: - Explore product functionalities at: https://guides.absinthe.network
- Explore the Adapter Library docs: https://docs.absinthe.network/
- Join our Slack community to hack on adapters and connect with the team: https://join.slack.com/t/absinthecommunity/shared_invite/zt-...

Actively AI| Multiple Roles | In office in NYC | Salary + Equity
What Cursor has done to revolutionize coding, we are looking to do for revenue. Every large company spends 40-50 cents of every dollar they earn on sales & marketing, and it’s very inefficient because data lives in so many different systems, sales reps are stretched thin doing manual work, and products are rapidly evolving.
It’s why we are building the agent and intelligence framework for enterprise scale GTM that guides every sales motion across the funnel — from SDR outreach to AE deal strategy to cross-sell and expansion. It’s an intelligence layer that sits on top of every sales tool and with external browsing that is then customized to your specific products & GTM motions.
It’s a massive technical challenge: - Intelligence at scale: modeling millions of accounts, real-time signals, and contextual history into per-account reasoning agents. - AI Agents & Chat: designing systems across “push” (recommendations) and “pull” (interactive assistants), with extensible skills customers can train themselves. - Data & Infrastructure: creating a new framework for real-time, per-customer agents that simplifies pipelines, scales efficiently, and cuts costs (we’ve already cut cost per account by 50% through smarter eval-driven approaches). - Wall-to-wall product: from self-serve UI to Slack integrations, from predictive models to generative copilots — we’re building an AI operating layer for GTM.
Why Join Engineering at Actively: - Customer-driven impact: engineers directly go onsite and spend time with customers, deploying agents that reshape workflows at companies like Samsara and Justworks. - Category creation: there’s a huge opportunity to build the pre-dominant AI company for GTM with a massive TAM - Cutting-edge AI: opportunity to push the frontier of reasoning agents, eval-driven development, and scalable intelligence. - High-caliber peers: we’re ex-Instacart, Scale AI, Stanford AI researchers, and operators who’ve built at scale before.

You'll enjoy this role if:
- You like going 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- Be capable and excel on your own, but be humble and communicate well with others as projects require more collaboration

Hi, I saw you had a couple openings for your company.. are both remote positions for those in the UK only or are you open to those in the U.S. as well?
You can be remote as long as your timezone is between UTC -2 and UTC +8. That covers most of Europe, Africa, and all of North and South America.
Minor point, but I think you've got your signs backwards. Eastern Europe is UTC+2, and PST is UTC-8.
Ah ok, appreciate it.

Oils (https://oils.pub/) | Language Engineer / Debugger of Other People’s Cursed Shell Programs / Writer | REMOTE (non-US) | 50 euros/hour
Oils is our upgrade path from bash to a better language and runtime.
We’ve been awarded a 4th grant from https://nlnet.nl, and our focus is to show that OSH can be the ONLY shell on a Unix system, which is hard
It looks like we will reach this goal! Other than me, there are 4 people working PART TIME on this, and we can use more help.
If you like hunting down difficult bugs, and are skilled at Unix and Python, this could be a good fit.
Most bugs are too hard for 1 person to fix by themselves, so communication is important. And writing good test cases is important.
We’re also paying people to do polished writing, since we'd like to spread the word
Starting from 131, we’re down to 41 disagreements between OSH and sh/ash/bash, when building ~1600 packages in Alpine Linux
https://op.oils.pub/aports-build/published.html
Anyone who's not “scared” of these bugs is probably a good fit, and you can do as much or as little as you like. This is also an opportunity to get deeper into the interpreter
Communication happens on Zulip, and we also have video meetings approximately every 2 weeks
I'll have a blog post explaining this work soon, but feel free to e-mail me if this (unusual) job matches your interests. Any questions are very welcome, and you can dip your toes in to see if it works for you
I wrote this page a few years ago to help people assess the fit: https://github.com/oils-for-unix/oils/wiki/Where-Contributor...
The job is remote-only, and we slightly prefer non-US contributors due to our funding
Tech stack: Python, Shell, perhaps C++

Looking for something more meaningful? How about the opportunity to have a direct impact on the property maintenance experience for hundreds of thousands of residents?
Welcome to the future of property maintenance. Property Meld’s vision is to radically improve how the property management industry handles property maintenance. If you’ve ever had a maintenance issue at your housing rental, you know how much of a pain it can be to get it fixed quickly and reliably. It doesn't have to be this way. We're rethinking the entire property maintenance experience from the ground up with two things in mind - first, driving the cost of doing maintenance to the absolute minimum, and second, providing an experience to residents and property owners that makes them want to stay with their property manager. If you are excited about turning something that has historically been a negative experience (maintenance) into a positive experience, we'd love to talk with you.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs, and our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS or AI company, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.
Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

Modeling human societies and interaction dynamics is extraordinarily challenging yet potentially transformative—solving it could unlock breakthrough applications in simulation, prediction, and coordination. I believe multi-agent LLM systems with hive-mind architectures are uniquely suited for this because they excel at the very thing that makes human behavior hard to model: probabilistic, unpredictable dynamics.
As an open source contributor to claude-flow and claude-swarm, I've worked on systems where specialized agents (Queen orchestrator, Workers, Scouts, Guardians, Architects) collaborate through: - Task orchestration with decomposition, distribution, and progress aggregation - Consensus protocols with voting and tie-breaking for strategic decisions - Shared memory enabling collective learning and pattern recognition - Real-time coordination with auto-scaling, load balancing, and fault tolerance - Self-healing mechanisms that rebalance and recover from failures
This hive-mind approach demonstrates how agent collectives can achieve what isolated agents cannot: parallel problem-solving, emergent intelligence, and robust execution at scale. The probabilistic nature of LLMs—often seen as a limitation—becomes an asset when simulating the inherent unpredictability of human social systems.
I'm eager to contribute to teams working on agent societies, emergence, and collective intelligence. GitHub: https://github.com/Tar-ive

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?
We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen
Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.
Three open roles (apply below!):

krea.ai | Distributed Systems Eng. & Data Engineers | San Francisco (on-site), CA
I'm the cofounder & CTO of Krea (https://www.krea.ai). We are a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and professional creatives. Small team (~22); millions of active users; and raised over $83M from top Silicon Valley investment firms.
We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.
The job:
- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.
- Learn ML engineering from world-class researchers on a small tight-knit team. You’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions.
- Play with huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.
Tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational DBs, PyArrow, etc.)
You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for experience with dist. systems, k8s, and existing ML or data experience (but not required!). Cool side projects are a green flag.

Bubblehouse | Fully REMOTE | Full-Time | $200–250k | Principal Engineer
Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.
We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.
We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.
Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.
Looking for:
1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.
2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)
3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)
4. Broad experience across multiple programming paradigms, platforms and software stacks.
5. Demonstrated care for the software craftsmanship (which can take many forms).
6. Great spoken English, and ability to communicate 9am to noon in New York time zone.
We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.
Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.
(If you have applied before, no need to re-apply, we’ll reach out.)

We've been improving our hiring process over time, and we know some good candidates may have fallen through the cracks. Some people who tried in the past have had success going through it again, and we still pay for hiring projects.

I would advise people to steer clear for applying to DuckDuckGo.
They require two take home projects and poor communication/no feedback on projects submitted. Their glassdoor is adorned with similar feedback.
They've also been hiring for years, Cannonical and DuckDuckGo need to be banned from jobs' forums.
I got rejected within 30 minutes of applying so I guess I'm in the clear?

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time
MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.
We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Phrasing.app | Co-founder | EU Remote | Elixir | Clojure
Phrasing is a language learning app built by a polyglot, for polyglots. It was designed to be language agnostic, and currently fully supports over 80 languages. It brings a beautiful, simple, and addictive [1] learning experience to languages big and small, and helps users learn 2-10x more in the same amount of time [2].
The tech stack is a ClojureScript PWA on the front end, and an Elixir umbrella application on the backend. The data processing happens in Broadway pipelines, and are horizontally scalable with FLAME. All of the data is stored in Postgres, and most of the communication between the client and server happens with a custom local-second sync engine à la Linear.app.
The company is bootstrapped and bespoke. There’s no investors, there’s no AI generated code, no shadcdn UIs. I miss the days of the early internet, and acutely feel the mass enshittification of the web. I’m really trying to do something different with the experience as well as the business, all in hopes to bring back a little bit of that wonder that was so prevalent in the days of the early internet.
The app is all working, the experience is great, and the onboarding was just finished. I’ve been using the app now to successfully learn 18 languages [3] and it’s truly a joy to use. Just finishing up the new site [4] after feedback from our last launch and getting ready for more launches [5]. The new video has been getting some pretty rave reviews and is a good gentle introduction to the app [6]
For me, this app is a dream app. This tech stack is a dream tech stack. This company is a dream company. It’s hard to believe I’m the only one these would all be true for.
I’m looking for someone who believes in the product, mission [6], and tech to come in and help me turn this functioning application into something truly great. No experience is required — just a dedication for your craft, and the willingness to take a chance in something you believe in.
If you feel that this post was written for you, please write me a well written personalized CV to hn at phrasing dot app. Low effort applications will not receive a response regardless of your CV.

Conspiracies about fake hiring are getting really tiring. I don't know about Beacon AI, but we too have been hiring since last summer. Heck even longer than that. We are a small company and our headcount has not changed much in the past year. We hire some people and some people left.
FAANG are still hiring while their headcount overall has actually gone down in the recent past.

Maybe you need to do some due diligence with ghost jobs. It would make this platform better.
We don't have the resources to do that.
If you want a longer explanation, I wrote about this quite a bit in last month's thread—see https://news.ycombinator.com/item?id=45094555 and especially https://news.ycombinator.com/item?id=45118501.
But it's not that difficult to implement that functionality, if company posts more than 3 times a year you can ping them if they really are hiring.
We are not asking for policing but every publicly available forum is swamped with ghost jobs and consultancies which are basically farming resumes and personal data. It makes the internet barely usable. These are not good faith actors.
I have to disagree there—this is a complicated domain and I'm afraid it would be quite difficult to get right. For example, I'm sure there are quite a few legit companies posting more than 3 times a year. Excluding them wouldn't be a good strategy; they might well be some of the best places to get hired.
You're certainly correct that there are bad actors, on both sides of the hiring transaction—that is, there are fake jobs and also fake job applicants. Unfortunately it is a hard problem to solve, and we have no particular expertise in it.

Zoca | AI Engineer | Full-time | Bangalore (In-office)
I'm Shambhav, CTO & co-founder at Zoca. I'm building a team to push the boundaries of what's possible with AI.
So far, we've built a platform from Bangalore that has outperformed every competitor in our space — small businesses happily pay us 10x our competitors' price because our agents actually work. These agents work like real business partners, generate leads, do followups, book appointments, manage reviews and more. We're already powering growth for over a thousand businesses.
In the next 12 months, we're going to scale this to tens of thousands, while making the agents smarter, more reliable, and capable of things people think aren't possible today. We'll be working on technical challenges like multi-channel conversations, browser automation at scale, retrieval pipelines, and real-time monitoring/eval loops.
I need AI Engineers who want to build like founders — not paper over things in a research repo, but ship production systems that touch real users. Strong TS/Python skills, a builder's mindset, and a track record of actually building (agents, GSoC projects, or similar) is what I'm looking for.
If this excites you, send me an email at shambhav@zoca.com with your working demos or GitHub profile. Show me what you've hacked on.

You'll thrive here if you are a high-ownership individual ready to grow at full speed, value learning above other factors, and want the fastest path to growth (We have a two-quarter promotion policy), you are fully committed to transforming higher education (missionary, not mercenary).
Work Mode: Hybrid - Bangalore. 9 AM to 6 PM, 6 days a week. Product/engineering is in the office Wednesdays and Saturdays.

Introduction: I’m a Data & Analytics professional with experience spanning data analysis, business intelligence, and data engineering. Skilled in designing ETL pipelines, optimizing data workflows, and developing interactive dashboards that turn complex data into actionable insights. I also have hands-on experience applying machine learning techniques for prediction, classification, and NLP-based tasks.
Currently exploring opportunities for junior AI / AI data scientist roles, as well as data and BI-focused positions where I can contribute to data-driven problem solving and scalable analytics solutions. Open to full-time or contract roles in fast-paced, innovation-driven environments.

I'm a construction worker turned programmer doing data analysis for a few PhDs at a start up company. Recently got into machine learning and have been really going hard on it. In total I've been doing Python for about a decade.
Any advice for someone like me? I like my current job, but want to know where to go from here. Thanks for any advice.
