Project Debug | General Engineer | Singapore (HYBRID) | Full-time | debug.com
Project Debug raises, sorts by sex, and releases millions of (non-biting) male mosquitoes in Singapore to reduce the local mosquito population and prevent the spread of dengue and other mosquito-borne illnesses. Our trial in Fresno, CA showed a 95% reduction in female mosquitoes during the seasonal peak.
Our engineering team is pretty small and we need a solid generalist engineer who is interested in becoming a domain expert in our factory, where we do automated rearing and sex sorting. If you run a homelab, have tinkered with Arduino, and can prompt/write some Python, we can teach you everything you need to know about our stack (Go, Python, React, Kubernetes, Tensorflow).
Reach out to [email protected] and please mention HN in your email.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite
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 software engineers for many roles. You 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)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations and we need experienced 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!

Startup working on AI Healthcare solutions (plus some random experiments) | REMOTE(US, Pacific time zone) | Full time and project based
Full time engineering role (Remote, US person required; Pacific time zone)
Stack: C#, Python, Gemini API on Windows, lots of legacy systems/constrained enterprise environment. Health systems experience preferred. Understanding of cost effective, reliable LLM API use. Should be flexible: do PM-like work with less-technical client domain experts, solve problems end to end, willing to data cleaning and detailed work for client goals and security/compliance gruntwork, even when it's not technically elegant. Self motivated, willing to understand legacy and undocumented codebases, but also willing to take instructions.
Ideal candidate has real (pre-Claude Code) experience, but is ready to do fast iteration in post-AI world, while actually reading what the AI does. We're ok if your stack is different, if you're both technically mature and up to date on modern fast-turnaround AI-based development. Probably in the 5+ year experience range.
REMOTE anywhere, project based or initially part time: startup generalist hacker, maintain systems and websites, code one-off prototypes. Should be good enough to code without an AI in a few languages, but an effective AI harness coder. Can do a small but complete app/project end to end, including basic marketing. 2+ year exp or a new grad with a good portfolio or major project; happy to consider more experienced person. Good role for someone who's working on their own startup to pick up some side money and experience. Projects could be anything from game-like apps/novelties to voice tools to utility apps.
REMOTE anywhere, project based or initially part time: help on some more experimental mathy projects. M.S./Ph.D. in statistics, physics or related, with pragmatic programming experience. Possible projects: gaussian process modeling; designing evaluation metrics; compression; Bayesian tools for radiology imaging. May be good for a grad student part time. This is the fun stuff the founder would rather be doing himself if he had the time.
REMOTE (US person) Half-time remote admin/chief of staff type: deal with bookkeeping, compliance, communications, social media, phone calls - save us time on everything non-technical. Should be effective AI user; should have some relevant experience supporting tech business.

My name is AJ Forsythe and I'm the Founder / Chief Chicken Tender at Coop! We're an Austin TX based company on a mission to build the world’s largest decentralized food production network, starting with AI powered chicken Coops. We’ve been in the market for about 18 months and our customers are in 48 states and will generate about >10M eggs this year. It's insanely fun to work on and we have a shot at building a huge business in the connected urban farming space. If you’re big into computer vision, consumer products that are fun, and an awesome team we would love to chat. The Coop has an automatic door + cameras doing computer vision work (predator detection, egg alerts, remote health monitoring, etc). It's a super exciting time and are seeing directional product market fit which I'm thrilled about. Seriously go check out our website, it's a super fun + amazing product.
We’re a tight-knit team of 5 people with 15+ years of experience working together. We’ve been through YC, started and scaled multinational million-dollar businesses together, taking them from idea to acquisition by a Fortune 50 company. We’re gritty and passionate without taking ourselves too seriously - and we’re here to build something really exciting that helps people reconnect with their food and the planet. We're VC backed (call it $5M) by some of the world's best investors but we are a scrappy small team that moves fast.
We have an absolutely fantastic CTO Ryan that I'm looking for his / our right hand person to work alongside with. I think the term full stack is overused but that's closest to what we're looking for. Also this really isn’t a traditional Eng role, I look at it as we’re a small growing team and you would be one of us working on a ton a cool projects on day 1. Also, we LOVE working with founders so if you've started a company before that's epic.
You can also reach out to me directly at: aj[at]coop.farm - Just email me your LinkedIn / GitHub / portfolio + why you think you'll be an awesome fit and I'll respond. Please don’t use GPT too much. This is my 3rd company (2 have exited) and I want to build the super solid core team and you might be the perfect fit for us and vice versa.
