Summary:

This role is for a senior technician who can run difficult jobs including tight-tolerance work on large apertures, exotic materials, and multi-element assemblies mentor others, improve process repeatability, and partner with engineering and quality to drive yield, throughput, and consistency.

Key Responsibilities:

• Independently set up and run complex or high-value optical fabrication jobs with minimal supervision, including tight-tolerance work on challenging substrates and geometries.
• Operate and optimize conventional fabrication processes including grinding, lapping, polishing, beveling/chamfering, and edge finishing across a range of optical materials (glass, crystalline, IR-transmitting, and specialty substrates).
• Work from optical drawings, travelers, process routings, and specifications to deliver parts to tight requirements.
• Perform advanced in-process and final inspection using shop metrology and optical inspection tools including:
• Interferometers (Zygo or equivalent) for flatness, transmitted wavefront, and surface figure
• Autocollimators for wedge and angle verification
• Micrometers, calipers, and electronic/dial indicators
• Microscopes and visual inspection tools for cosmetic evaluation per applicable specs
• Surface profilers or other metrology equipment as required
• Drive process control for critical features including thickness/parallelism, wedge/angle, flatness, edge condition, and cosmetics.
• Troubleshoot process and equipment issues; identify root causes and implement corrective actions in coordination with engineering and quality.
• Mentor and train Technician I and II personnel on setup standards, workmanship expectations, safe handling, documentation/traceability, and quality acceptance criteria.
• Support development and improvement of work instructions, process documentation, and standard methods.
• Lead by example in safety, cleanliness, organization, and quality discipline.
• Support production planning and priority execution by coordinating with supervisors and cross-functional teams.
• Contribute to continuous improvement initiatives to improve yield, cycle time, and repeatability.
