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.

As a Laboratory Technician at General Matter, you will provide critical hands-on support to our Chemistry team as we scale uranium enrichment operations. You'll work in a highly regulated laboratory environment, performing sample preparation, equipment maintenance, and quality assurance activities that directly support our R&D testing and product certification efforts. This is an excellent opportunity for early-career professionals to gain practical experience in analytical chemistry and nuclear materials handling while contributing to a mission of national importance.

You'll work alongside experienced chemists and scientists in a fast-paced, safety-first environment where precision, attention to detail, and rigorous documentation are essential. If you're looking to build your career in a high-impact field and are excited by the opportunity to support the nuclear Renaissance, we encourage you to apply.
