Mechanical 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 a General Matter Mechanical Engineer, you will design, build, test, and own the mechanisms and mechanical structures enabling enrichment technology. You will work closely with cross-functional teams, including electrical engineers, software engineers, chemical engineers, manufacturing engineers, nuclear engineers, materials scientists and physicists. 

• →Develop mechanisms and mechanical structures for enrichment and own them through the entire product lifecycle including requirements definition, design, development, qualification, and release to production.
• →Support optimization of designs for cost, performance, and manufacturability.
• →Functionally test your hardware through thermal, vibe, shock, durability, etc.
• →Perform root-cause analysis on test failures and develop hardware mitigations.
• →Participate in design review and provide feedback to ensure design objectives are met.
• →Work closely with electrical, software, manufacturing, and nuclear engineers to ensure designs are effectively integrated with overall system requirements.

• 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 mechanical engineering experience via project team, research, internship, and/or professional experience.
• Proficient in a 3D CAD package (such as Solidworks, CATIA, NX, etc.) and the ability to make manufacturing drawings using GD&T.
• Proficiency in finite element analysis (FEA).

• Strong understanding of engineering fundamentals.
• Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information.
• 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.

• Ability to work extended hours and weekends as necessary.
