Materials & Process Engineer

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 our Materials & Process Engineer, you'll be the materials generalist those teams rely on: the person who owns how metals are selected, characterized, and qualified across our hardware, and who bridges our chemistry and materials-science work with the engineers designing, building, and testing real components.

This is an engineering role. You care about how a material behaves in service, under load, temperature, and demanding environments, and how to get it reliably into production, not about formulation for its own sake. You'll sit squarely at the interface of chemistry and hardware development, working shoulder-to-shoulder with design, manufacturing, and test engineering every day.

If you seek high impact and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to apply to join our team.

Materials & Process Development

• Own the selection, characterization, and qualification of metallic materials across General Matter's hardware

• Develop physical, mechanical, and thermal property data and design allowables to support hardware design decisions

• Define and improve manufacturing and special processes for metals (e.g., heat treatment, welding).

• Drive material and process choices that increase reliability and reduce cost as we move from development into production

Cross-Functional Interface

• Serve as the connective tissue between chemistry / materials-science and hardware development, translating materials constraints into engineering decisions and back again

• Partner daily with design, manufacturing, and test engineering to solve complex materials and process challenges on current and next-generation hardware

• Provide technical review of drawings, specifications, and material requirements

Characterization & Failure Analysis

• Lead root-cause investigations using fractography, metallography, and mechanical testing

• Establish characterization and inspection methods, including non-destructive evaluation, to control quality across metals

• Build the data, documentation, and standards that let materials decisions scale with the company

• Bachelor's degree in materials engineering, metallurgical
