  • Experience working with precision optical and mechanical metrology equipment.
  • Experience with root cause analysis efforts and performing rigorous data analysis, post-processing, and test report generation.
  • Excellent communication, presentation, and organization skills.
  • Excited to work in a fast-paced environment with new challenges each week.

Nice-to-have Skills

  • Proficiency in CAD (SolidWorks preferred) for test fixture design.
  • Experience assembling and characterizing moving mechanism assemblies.
  • Exposure to design and analysis of optical components and systems.
  • Experience working in cleanroom environments.
