  • Support fabrication improvement projects that enhance yield, repeatability, throughput, and process capability.
  • Introduce new optical processes into manufacturing by creating process plans, selecting tooling, defining work holding methods, and establishing in-process inspection steps.
  • Establish and optimize blocking and deblocking processes for a range of optical geometries and materials, with consideration for alignment, bond integrity, thermal effects, removal forces, and risk of part damage during fabrication.
  • Apply structured problem-solving to diagnose fabrication issues using root-cause analysis, process data, operator feedback, and metrology results.
  • Partner with quality and metrology teams to verify product conformance and improve correlation between in-process measurements and final optical requirements.
  • Collaborate across engineering, manufacturing, quality, and planning to standardize best practices and implement process improvements.

Qualifications:

  • Bachelor’s Degree and minimum 9 years of prior relevant experience. Graduate Degree and a minimum of 7 years of prior related experience. In lieu of a degree, minimum of 13 years of prior related experience.
  • Ability to obtain a Secret security clearance

Preferred Additional Skills:

  • Independently coordinate complex manufacturing and measurement activities.
  • Experience with large-aperture optics or other demanding precision components.
  • Experience resolving problems involving both fabrication and metrology.
  • Strong communicator, written and verbal communication skills within and outside of function.
  • Background in optics, precision machining, polishing, metrology, CNC, or process engineering.
  • Working knowledge of optical metrology methods including interferometry, profilometry, spherometer, thickness measurement, and cosmetic inspection.
  • Background in design for manufacturability for optical components.
  • Strong, specialized knowledge of optical fabrication consistent with Lead technical roles.
  • Requires strong knowledge of optics manufacturing.
