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 katejm@debugproject.com and please mention HN in your email.

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!

Hi HN! We’re a YC-backed, Series-A startup building robots that build large-scale solar farms.

Check out a video of our first system here! https://youtu.be/ZZ2fP1Y5Z2E

It turns out that construction companies literally can't build solar fast enough, so what we're doing is a crucial part of switching the grid over to renewable generation.

You’ll be a key contributor, helping bring our next generation of mobile solar factory to life.

Come work with us if you love:

* Fast-paced prototype development with software and hardware components

* Making a positive climate impact through your work

* Hacking on massive construction equipment!

  We're a systematic energy forecasting and trading company working to make the grid more predictable and reliable. We ingest a lot of messy, heterogeneous data (market, generator, weather, outage) and build models to forecast it. You would work closely together with the founders and take over the technical direction for our data systems end-to-end. Team is ex-D.E. Shaw, Optiver, and Stanford. We're bootstrapped, profitable, and growing. Compensation is all-cash and paid from company profits, not venture funding.

  What we're looking for:
  - 4+ years shipping and maintaining software
  - Strong Python skills (writing, maintaining, packaging)
  - Experience with multiprocessed and HPC workloads
  - Crisp written communication — we're deep-work focused and async-heavy

  Nice to have: data lake / Parquet architectures, Rust (esp. PyO3 extensions)

  Remote-first. We meet in person multiple times a year. Non-US candidates welcome if you can overlap 4+ hours with PST.

  Apply: email hiring@amplifyrenewables.com with resume + an (optional) short note on a data platform problem you've owned. Please mention HN.

Company: We’re building a geologic modelling software, based on reasoning, to help mining and mineral exploration companies work faster. Our goal is to create a way to enable open-ended, interpretive geologic problem solving to be done programmatically, changing the way to explore for hard rock and critical minerals. Currently in active fundraising.

Role: You are the founding engineer on the team, joining co-founder (Neil, CEO) and myself (Jeff, CTO) as first employee. You’ll have a deep influence over systems and architecture. You will have ownership through the entire stack from the database, through geostatistical backend services, through 3D rendering on the client side.

Work rooted in agentic systems, so an understanding of the internals of things like Claude Code, and a broader understanding of orchestrating agents to complete complex discrete tasks is important.

You:

- Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium)

- Eager to learn about mining domain knowledge around the software.

- Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.)

- Open to doing a yearly month abroad with Neil and I. Last year, it was Oaxaca, Mexico.

Apply: Shoot me an email at jeff@deepcoretech.com with a resume, and a short blurb about yourself. If you include a 1 minute video/Loom, I'd love to see it. Must be eligible to work in Canada without a VISA requirement. We are located in Squamish, BC.
