Job description

About the Company General Matter enriches uranium. We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US. In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume. Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way. Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable. We believe abundant nuclear energy will lead to a post-scarcity society. We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms. 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. About This Role As a Tooling Engineer, you will own the design and build of critical infrastructure for the development, manufacturing, and production enrichment systems. You will design, source, operate, and maintain custom tooling and fixtures that enable safe, repeatable, and scalable manufacturing operations. You will collaborate with engineering and production teams to creates jigs, fixtures, and assembly aids, from rapid prototyping to sophisticated tooling. If you seek high-impact and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to reach out to join our team. Responsibilities: Design and develop custom tooling, jigs, and fixtures using CAD software that support rapid prototyping and large-scale production. Own the fabrication, assembly, wiring, and validation of tooling, fixtures, and test systems. Ensure tooling design meets safety, ergonomic, and operational requirements. Collaborate with machinists, welders, engineers, and technicians to optimize designs. Provide troubleshooting for production tool issues. Basic Qualifications: Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc). Bachelor’s degree in Mechanical Engineering or a related field. 3+ years of tooling or fixture design experience. Proficient in a 3D CAD package (such as Solidworks, CATIA, NX, etc.). Knowledge of GD&T and machining processes. Preferred Skills and Experience: Strong understanding of engineering fundamentals. Experience in automotive, aerospace, or similar industries requiring custom tooling and complexity. Knowledge of additive manufacturing for rapid tooling. Experience in a fast-paced engineering environment or a highly technical role requiring a resourceful, entrepreneurial approach to complete tasks within tight timeframes or budget constraints. Lean manufacturing and ergonomic design knowledge. Additional Requirements: Ability to work extended hours and weekends as necessary. Compensation and Benefits: The base salary range for this role is $90,000–$175,000 annually. Compensation bands are determined by role, level, location, and alignment with market data.
