I'm Gio, CTO of Foundry Robotics. We're an early stage London-based startup building robotic solutions for manufacturing applications.
We have 3 open positions:
1) Tinkerer/mechanical engineer -- Help us build our robots in our lab with a mixture of design and hands-on prototyping. Experience with metal fabrication (CAD, CNC milling, turning, 3d printing, sheet metal).
2) Software/robotics engineer C++/Python -- Help us build our software with a lot of autonomy. Navigate documentation for the different components and technology options and make key decisions. Path to become a team lead. Experience in robotics is not required if you have experience in adjacent fields such as 3d graphics (game engines for example).
3) Robotics research engineer -- Be our first research hire. Experience with computer vision, NVidia Isaac or similar simulation environments. Background in reinforcement learning.
Contact: gio@foundryrobotics.co.uk (add "HN" to subject)
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.

Hey HN! I'm Alexander, one of the founders of Hatchet. Hatchet is an open-source platform for running background jobs at scale.
We're hiring engineers who are excited to build the next class of engineering primitives, starting with queues, background tasks and durable execution. We started in early 2024 after launching our distributed task queue (https://news.ycombinator.com/item?id=39643136).
Hatchet is currently used by thousands of engineers for all kinds of workloads: log ingestion pipelines, code review agents, video encoding, GPU scheduling, etc. Our target customer is fast-growing startups who have a strong need for background jobs system. These days, that tends to be AI companies, though we're general-purpose and not exclusively targeted for AI workloads.
Stack: Postgres, Go, Typescript, React, Kubernetes

Anyways, the concept looks cool, but I'm failing to see a real value add to something like Temporal. What is it?
Regarding Temporal, our goal is to create the best developer experience possible, and we started Hatchet because we felt that Temporal misses the mark (I used Temporal for years before starting Hatchet).
The primary difference is that we're not solely focused on durable workflows, we're a general-purpose background jobs platform which offers durable workflows as a feature. In our view there are a set of equally important primitives: tasks, events, streaming/pubsub, concurrency, priority, rate limiting, scheduling, and yes, durable workflows.
Tasks being the entrypoint to the platform, rather than immediately dealing with the overhead of durable workflows, generally makes Hatchet easier to adopt for engineering teams. I wrote a little more about how task queues relate to durable execution here: https://hatchet.run/blog/durable-execution
We've also invested quite heavily in platform features like logging, observability, alerting, and our UI which either aren't offered or are underdeveloped in Temporal.
But ultimately I'd encourage people to give both a try - we're both MIT licensed and can easily be run locally.
Looks interesting.
We are in the process of looking for some alternatives to temporal/prefect. Would you mind sharing your email so I can send a few questions along with my cofounder?
We're creating state of the art AI models, including the leading foundation model for Deepfake Detection. Looking for full stack, frontend and machine learning engineers that would love to create prototypes directly with the founders.
Here's what we're looking for:
Full Stack Engineer - We are seeking a skilled Full Stack Engineer with experience with both Javascript and Python to join us. The ideal candidate will have a strong background in building and deploying web applications, a passion for working on cutting-edge AI technologies, and the ability to collaborate closely with our founders to create innovative prototypes.
Product Lead - Ownership over our security AI model product suite. Lead technical + product conversations with customer engineering/security stakeholders.
Solutions Engineer / Forward Deployed Engineer - Own technical success for enterprise integrations: take customers from first POC → production rollout → expansion. Partner with product/engineering to turn customer friction into roadmap, and advocate for the highest-leverage fixes.
If interested, reach out directly to me: zohaib [at] resemble.ai
If you discover the best AI detection technology, then it will eventually be used as a (negative) reward function in training future models. It's an arms race.
Would you be open to alternative techniques, like metadata, source analysis, or online (fuzzy) reverse searching? Consider that judges and court experts don't rely solely on the evidence itself to determine if it's 'real', but to an even greater extent they rely on how it was collected, if evidence has not been sourced correctly, judges don't even look at it.
We've also been doing active work in source tracing: https://github.com/piotrkawa/audio-deepfake-source-tracing
We build mobile apps and supporting systems for long-haul truck drivers.
We have a critical DNS registrar/hosting migration to do this year and while I did the last one (on a less-critical domain), I'd really like support from someone who has done >5 of these to help our team get it right. Good news: no DNSSEC. =)
Please reach out to me at phil@eleostech.com and mention this post if this is you and you have a reference or two. It should be really easy project for the right person, but we'll compensate commensurate with the business risk.
There's definitely a way to do it without downtime.
We're building an agent to manage single family rental properties across the United States. We currently manage ~4,000 homes, are growing quickly, and are looking for full stack, backend leaning engineers who would love to contribute to a state of the art agent.
I've written a bit about our culture + product before:

If interested, reach out directly to me: michael@thisismason.com
I'm a software engineer but (thanks to my elderly father) I know the super fine details of rental property management.
For what it's worth, when I started out in 2023, the business was -1.3 million USD in construction debt. In 2025, 2 years into my role and we're at no debt, 34 fully occupied homes and 3 luxury villa sales. I can 100% provide documentation to prove this.

We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—a platform that processes terabytes of genomic data to accelerate antibody discovery and drug development.
We are a deep-tech research lab, not a typical SaaS. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + biological nuances) requires high-bandwidth, in-person collaboration.
We are hiring for two core roles:
1. Senior Go Engineer: You will build distributed systems for high-load genomic data processing. This is not CRUD. We need someone who understands memory management, concurrency, and algorithmic efficiency at scale.
2. Bioinformatics Developer (Antibody Discovery): You will work on the scientific core, developing blocks for NGS data analysis and antibody structure prediction. You should be fluent in both code and biology.
The Offer:
Comp: Top-tier EU salaries (~€90k - €120k).
Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions).
The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin.
Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have."
Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search).
Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.
Process: No HR screening. You will talk directly to the engineering team.
Email me (I am the CEO): stanp@milaboratories.com. Please mention "HN" in the subject and include your GitHub.
The 'Beckham Law' (24% flat rate) applies to the rest of Spain. Bizkaia has fiscal autonomy and a different system to attract talent: you get a 30% exemption on gross income plus you can deduct specific expenses (like your apartment rent, school fees, etc.) from the taxable base.
The total tax exemption can reach up to 50% of your gross income.
This stacking effect (exemption + expense deductions) is why the effective rate here often drops well below the national 24%. For example, on a €100k salary, your effective tax rate typically lands between 15-20% (depending on your rent and family status).
We're building AI-driven turrets that stop hostile drones - where robotics needs F1-level speed.
We're looking for smart, T-shaped teammates: people who are experts in one area but happy to jump in wherever needed. Our software team is small, so every member makes a real impact.
If you want to write motor control in Rust, optimize camera processing with custom CUDA kernels on Jetson, or rework a transformer-based tracker to handle small objects - you can do that here, and much more.

> Please state the location and include REMOTE for remote work, REMOTE (US) or similar if the country is restricted, and ONSITE when remote work is not an option.
We have preferences in terms of where we hire, but remote work is an option depending on the individual and where they are located.
So some jobs are hybrid onsite and some are fully remote but even if i said just now that all jobs can be remote, some jobs aren’t really fully remote because I can’t envision it in my mind that they would be effective fully remote, even though I myself am fully remote.”
Did I understand what you wrote properly?
Hi Josh,
Thanks for sharing this. I’m very interested in the Senior Systems Engineer role on Durable Objects.

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.
Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.
As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.
We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

Question, while imaging is a bit less common in pediatrics. How are you handling medical images and bloodwork?
It seems like being a pediatric service, there's an opportunity to take ownership of these medical documents, both for life-long storage and centralization. Also if tech is a brand differential it seems like it would be a simple place to get a competitive advantage.

Sleep is vital to recharging mentally, restoring our bodies physically, and fighting off disease. Sleep is so core to our health that it's the activity we all spend most of our life doing. Yet sleep disorders are some of the most underdiagnosed health conditions on the planet, with an estimated 80% of obstructive sleep apnea patients undiagnosed and untreated
EnsoData uses machine learning, integration with pulse oximeter hardware, mobile apps, and clinician review UIs to automate sleep study scoring and give sleep clinicians tools to find and help patients with sleep disorders.
We're hiring a product manager to uncover what features our customers crave most, conduct discovery research in the sleep industry, define and prioritize product requirements, partner with engineers to ship features, and work with marketers to tell compelling product stories. You'll manage the product development process from whiteboard mockups tested with real users through to detailed specs and launch, breaking down ambiguous problems into releasable slices that bring AI-powered sleep diagnosis to more patients.
Gobii is the easiest way to deploy browser-use agents in the cloud or on-premises. We're building an open-core AI workforce platform—browser-native agents and automation tools. We have paying customers.
The entire team contributes to browser-use. We also have contributors to Apache NiFi, LiteLLM, and RA.Aid (open-source coding agent I created). Open source is core to how we build and how we think. We're backed by Open Core Ventures.
HQ is San Francisco, but much of the team is in the DC area. East Coast timezone preferred, DC area even better—but we're fully remote.
What we're building: The orchestration layer for browser-use and AI agents. Systems that navigate, reason, and execute on the real web.
Who we're looking for: You've built agentic systems that shipped to production. You have opinions about tool use, context management, and why most "agents" are just glorified prompt chains. You strongly prefer working in the open—a significant part of this role is contributing to OSS repos. We strongly prefer candidates with existing open source contributions.
Why now: We have strong traction and are expanding the team. You'd be early—with real influence over product, architecture, and how we work. High autonomy, high trust, small team of people who know what they're doing.
Comp: Cash + healthcare + modest 401k match + options. In line with SF-based VC-backed startups at pre-seed stage.
Stack: TypeScript, Python, browser automation, LLM orchestration.

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 credentials. 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.
We are hiring skilled 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 have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. 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 ambitious to get outcomes for our customers and their constituents. 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, figure out stablecoin payments, 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.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!
Our products:
* Merge Queue: Ensure your PRs keep the builds you care about green at any scale.
*Flaky Tests: Detect and eliminate Flaky Tests.
Unlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobs
