Optical Fabrication Engineer
Our successful Lebanon, NH client is seeking an Optical Fabrication Engineer for their precision optics production team! The ideal candidate is a deeply skilled fabricator who understands why processes work, not just how to run them, and who can diagnose yield and quality issues from first principles. This direct-hire role offers comprehensive benefits, continuing education and professional development support, and performance-based annual bonus opportunity.
Responsibilities of the Optical Fabrication Engineer
- Develop, qualify, and document loose-abrasive grinding and pitch-polishing processes for flats, spheres, prisms, and wedges across optical glasses, fused silica, calcium fluoride, and crystalline materials
- Own process development, yield improvement, and technical problem-solving across the conventional fabrication floor
- Work directly with metrology and engineering to qualify new part families
- Serve as a senior technical mentor to optical fabrication technicians
- Lead root-cause analysis on yield loss, scrap, and rework; implement preventive measures with measurable impact
- Author and maintain work instructions, SOPs, and process travelers for conventional fabrication operations in ERP system
Qualifications of the Optical Fabrication Engineer
- Bachelor's degree in Optical Engineering, Physics, Materials Science, Mechanical Engineering, or a related technical field, with 5+ years of hands-on precision optical fabrication experience in a defense, aerospace, or scientific optics production environment; OR 10+ years of directly applicable precision optical fabrication experience in lieu of a degree, with demonstrated expertise across grinding, polishing, metrology, and complex geometry work
- Demonstrated expertise in conventional (non-CNC) fabrication processes: loose-abrasive grinding, pitch polishing, double-sided lapping/polishing, and prism work
- Proven ability to independently develop and qualify fabrication processes from raw blank through finished component
- Track record of solving complex yield, figure, or finish problems through first-principles analysis
- Deep working knowledge of optical fabrication physics: Preston equation, Hertzian contact, SSD mechanics, and pitch rheology
- Expert-level pitch polishing tool preparation, lap conditioning, hand figuring, and full-aperture convergence
- Double-sided lapping/polishing experience on SpeedFam, GlassMaster, Lapmaster, or equivalent planetary machines
- Prism fabrication experience including angle control, blocking, and arc-second measurement
- Proficient with Zygo interferometers and MetroPro; able to interpret Zernike, PSD, and slope data
- Able to read and interpret optical drawings per MIL-PRF-13830B and ISO 10110 (all applicable parts)
- Solid grasp of ASME Y14.5 GD&T as applied to optical components
