Charge Robotics | Multiple Roles | Full-time | Onsite | SF Bay Area

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!

xdof | Robotics Engineers, Infra Engineers, Product Engineers, GTM | SF Bay preferred, NYC & Remote possible for non-robotics roles

At xdof, we're at an inflection point. Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We're building the foundation behind the foundation models – the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain – to help our partners drive the field forward.

Founded by UC Berkeley Robotics PhDs and MechEs, this is a team that executes across software, hardware, and operations faster than I can believe sometimes. This speed and ability to deliver has led to partnerships with many of the top players in the space.

We are not quite yet out of stealth, so not able to share more details here, but are so understaffed relative to demand that I'd like to start semi-public hiring ASAP.

Cybersecurity/AI seed startup | Founding AI Engineer | Bay Area | Full-time

We're seed-staged, 3 people, building an AI for cybersecurity, looking for a founding AI engineer who wants to learn/apply SOTA techniques for AI. Ideal background is experience building production agentic AI systems (by this I mean something like Simon's definition: https://simonwillison.net/2025/sep/18/agents/ definition) who also likes to think about WHAT to build and not just how.

We are a Golang/Python shop (although I'm not sure that matters so much any more).
