  • Perform tolerance analysis (GD&T) to ensure optical alignment and system performance
  • Collaborate cross-functionally with optical, electrical, and systems engineering teams
  • Support prototype builds, testing, and validation, including troubleshooting and design iteration
  • Ensure designs meet ruggedization requirements (shock, vibration, thermal stability)

Qualifications;

  • Bachelor's degree in Mechanical Engineering or related field
  • 3–10 years of experience in mechanical design (level flexible based on candidate)
  • Experience with precision mechanical design and tight tolerance assemblies in rugged environments
  • Proficiency in CAD tools (SolidWorks preferred)
  • Strong understanding of GD&T and tolerance stack-up analysis
  • Experience working in cross-functional engineering environments

Salary Range: $100k-$140k
