Manufacturing Engineer – Tooling & Fixtures

General Matter is enriching uranium in America.

Our goal is to design, build, and operate the world’s lowest-cost enrichment services in the United States.

Our mission is to restore America’s ability to produce nuclear fuel—fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors.

Ultimately, our work will help power national ambitions and enable a high-energy society.

We were incubated by Founders Fund, like Anduril and Palantir before us, and 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.

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable.

We’re standing up a new manufacturing facility and need a Manufacturing/Tooling Engineer to design the fixtures and workholding that make it run. You’ll own part-holding for our CNC mills and lathes from the ground up — designing, building, and qualifying the tooling that lets machinists hit tolerance and cycle time on every new part. This is a hands-on role with real design authority - your fixtures go straight onto the shop floor, and you’ll work directly with machinists and CNC programmers to solve problems as parts move from first article to production. If you want to design tooling that actually gets used the same week you build it, this is that role.

• Design fixtures, jigs, and workholding for CNC milling and turning, from concept through detailed CAD models and drawings.

• Partner with machinists and CNC programmers to validate fit, rigidity, and cycle-time impact of new tooling before it goes into production.
