About the Company

General Matter is enriching uranium in America.

Our mission is to restore our country’s ability to make nuclear fuel. Our fuel will help power AI, manufacturing, and other critical industries. It will power our next generation of reactors. Ultimately, it will power our national ambitions.

We were incubated by Founders Fund, like Anduril and Palantir before us, and we are backed by top tier investors.

Our lean, world‑class team of engineers and operators is applying a first‑principles approach to solving the problem of nuclear fuel production.

We are a mission‑driven company with a culture of urgency, accountability and transparency.

About This Role

As a software engineer, you will own and evolve the software infrastructure that supports hardware testing and system validation. This role includes developing and maintaining software for our Hardware‑in‑the‑Loop (HITL) testbeds, automating Acceptance Test Procedures (ATP), and building robust tools that enable fast, reliable testing across engineering workflows. In addition, you will lead the development and management of our telemetry systems for development environments, ensuring high observability, performance monitoring, and data accessibility across teams.

If you seek high‑impact and are excited by fast‑paced, intense, Skunk works‑style projects, we encourage you to reach out to join our team.
