Supply Chain Manager

General Matter•Los Angeles, CA

About The Position

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 General Matter Supply Chain Manager, you will own procurement and supply chain operations end-to-end. You’ll build vendor relationships, source components, negotiate pricing and contracts, manage materials availability, and design lightweight but scalable processes. You’ll work closely with engineering, manufacturing, and finance to keep development and production on track. This is a high-impact, high-visibility role ideal for someone who is both strategic and hands-on—comfortable optimizing cost structures one hour and chasing down a late component the next.
