At General Matter, we’re strengthening America’s capacity in nuclear energy to create a new set of possibilities, from generating clean energy at scale to forging energy security.

With nuclear energy powering the next wave of American progress, we’re ensuring our country has the fuel it needs for the next generation of reactors, no matter what’s happening around the world.

We 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.

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. If you seek high-impact and are excited by fast-paced, intense, Skunk works-style projects, we encourage you to reach out to join our team.

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.
  • 1+ 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 time frames or budget constraints.

Additional Requirements:

  • Ability to work extended hours and weekends as necessary.

Compensation and Benefits

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.

Base salary is just one part of your total rewards package at General Matter. You may also be eligible for long-term incentives, in the form of company stock options. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, HSA/FSA/Commuter benefits, and various other benefits.
