About the Company
At General Matter, we are enriching uranium for commercial nuclear power. Today the US controls less than 1% of global enrichment capacity and depends on foreign state-backed entities for our nuclear fuel, whether LEU or HALEU. We are fixing this, and are driving down the cost of enrichment to accelerate the growth of nuclear energy.
About This Role
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.
Responsibilities:
- 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.
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 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).
Preferred Skills and Experience:
- 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.
Additional Requirements:
- Ability to work extended hours and weekends as necessary.
Compensation and Benefits:
Base salary range: $70k to $170k + Equity (stock options)
