Mechanical Test, Optomechanical Systems

The role

You will build test infrastructure and execute test campaigns to qualify mechanical hardware for enrichment technology. This includes designing fixtures and testing precision optical mounts, alignment stages, and beam delivery paths.

What you will do

• Design, build, and maintain test fixtures, rigs, and setups for mechanical, thermal, vibration, shock, and durability testing.
• Develop and execute test plans to verify mechanical performance and alignment stability.
• Perform coupon- and component-level materials testing.
• Instrument test articles and analyze test data.
• Perform root-cause analysis on test failures.
• Own test documentation including plans, procedures, reports, and qualification packages.
• Improve test methods, tooling, and lab infrastructure.
• Work with mechanical, optical, materials, manufacturing, and nuclear engineers.

Required 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 experience in mechanical test engineering, environmental test, or hardware qualification.
• Hands-on experience designing and building test fixtures and instrumented test setups.
• Working knowledge of environmental test methods (vibration, shock, thermal cycling, thermal vacuum, durability/fatigue).
• Comfortable working directly with hardware in a lab environment.
• Ability to work extended hours and weekends as necessary.

Nice to have

• Background or working knowledge in materials science or metallurgy.
• Experience testing precision optical or photonic-based hardware.
• Experience with data acquisition systems, sensors, and test automation.
• Strong understanding of engineering fundamentals and statistical methods.
• Experience in a fast-paced engineering environment or a highly technical role.

Benefits

• Stock options
• Medical coverage
• Vision coverage
• Dental coverage
• 401(k) retirement plan
