Summer 2027 Internship - Mechanical Engineering

As a General Matter Mechanical Engineering Intern, you will gain hands-on experience designing, building, and testing the mechanisms and mechanical structures that enable our enrichment technology. You’ll work alongside experienced engineers and scientists across electrical, software, chemical, manufacturing, nuclear, materials, and physics disciplines to solve challenging technical problems and bring hardware from concept through build and test. This is an opportunity to contribute meaningfully to real engineering projects while developing practical skills in mechanical design, prototyping, testing, and cross-functional engineering.

• →Support the design of mechanisms and mechanical structures for testing and/or enrichment. You will experience the entire product lifecycle including requirements definition, design, development, qualification, and release to production.
• →Support optimization of designs for cost, performance, and manufacturability.
• →Contribute to testing hardware through thermal, vibe, shock, durability, etc.
• →Perform root-cause analysis on test failures and develop hardware mitigations.
• →Work closely with electrical, software, manufacturing, and nuclear engineers to ensure designs are effectively integrated with overall system requirements.

• Current undergraduate or graduate student pursuing a degree in Mechanical Engineering, Aerospace Engineering, or a related technical discipline
• Hands-on experience with mechanical design, prototyping, or analysis of structural or mechanism components
• Familiarity with CAD tools (NX, SolidWorks, or similar) and exposure to FEA or engineering coding languages like Python or MATLAB
• Collaborative team member who thrives in fast-paced, multidisciplinary environments and is eager to learn
• Strong understanding of engineering fundamentals.

• Ability to work extended hours and weekends as necessary.
