The role

You will build safety-critical mechanical systems for a nuclear reactor from CAD models and drawings. You will work with pumps, turbines, gearboxes, and pressure vessels while collaborating with engineers to develop assembly procedures.

What you will do

• Assemble safety-critical mechanical systems from CAD models, engineering drawings, and parts lists.
• Build systems correctly the first time as installed hardware cannot be serviced.
• Work with engineers to determine assembly sequences, tooling, and methods.
• Help write and refine assembly procedures, work instructions, and system manuals.
• Recommend design changes for easier manufacture, assembly, and inspection.
• Document every build including torque values, measurements, fits, clearances, and materials.
• Inspect parts and assemblies for conformance to drawings and specifications.
• Follow strict quality, cleanliness, and foreign material exclusion practices.
• Troubleshoot assembly problems and help engineering resolve nonconformances.

Required qualifications

• Ability to read and interpret engineering drawings, CAD models, and GD&T.
• Proficiency with precision measuring tools, including micrometers, calipers, bore gauges, dial indicators, and torque tools.
• Working knowledge of fits, tolerances, fasteners, bearings, seals, and shaft alignment.
• Clear, accurate written documentation skills.
• Strong attention to detail and a commitment to quality over speed.
• Ability to lift heavy components, work in a shop environment, and use rigging and lifting equipment safely.

Nice to have

• Experience in nuclear, aerospace, naval, defense, or other high-reliability industries.
• Familiarity with quality programs such as NQA-1, AS9100, or ISO 9001.
• Experience with ASME pressure vessel or piping codes (Section III or VIII, B31.1, B31.3).
• Experience building prototypes or first-article assemblies.
• Experience writing or contributing to assembly procedures or technical manuals.
• Rigging, crane, or forklift certification.
• Experience with laser alignment, leak testing, or pressure testing.
• Associate degree or certificate in mechanical technology, or equivalent military or trade training.
• An engineering mindset, with the ability to understand why a system is designed the way it is and suggest practical improvements.

Benefits

• Competitive base salary
• Equity ownership
• Comprehensive medical benefits
• Free daily lunch and dinner provided onsite
• Generous PPE stipend
• High-impact startup environment with significant ownership and autonomy
• Opportunities for rapid career growth and internal advancement
• Direct collaboration with experienced operators, engineers, and industry leaders
