Test Technician- Assembly B-Shift

About the role:

Test Technician performs final optical assembly optimization and testing to ensure accuracy, repeatability, and performance within defined requirements. The role executes optical tests, interprets results, supports mechanical and optical adjustments, and provides feedback on build quality.

• Perform optical testing accurately and consistently, including transmission, wavefront error, mechanical fit, and boresight error measurements.
• Perform assembly optimization activities such as mechanical alignment and shim adjustments using optical test data.
• Apply optical theory and terminology to interpret system performance and test results.
• Identify causes of variation in optical performance and troubleshoot test equipment issues, including alignment, sensor performance, and light‑source variation.
• Follow work instructions, engineering drawings, production routers, and other available information when instructions are not available.
• Follow production schedules to support on‑time completion of testing activities.
• Diagnose assembly failures and recommend corrective actions.
• Perform simple assembly functions as required to support testing and optimization activities.
• Comply with health and safety policies and procedures, company values, ethical conduct, and clean‑room protocols.

Bachelor’s degree in a four‑year college or university preferred, with an optical background strongly preferred. Associate degree in optics or equivalent technical discipline preferred. 3–5 years of related experience in optical testing, optical assembly optimization, or a combination of testing and precision optical assembly. Equivalent combinations of education, training, and experience may be considered.

• Strong understanding of optical theories and terminology.
• Ability to understand and interpret optical measurements and performance data.
• Experience using optical test equipment such as interferometers, spectrophotometers, power meters, beam profilers, or cameras.
• Ability to identify adjustable parameters that influence optical performance.
• Ability to diagnose test and assembly‑related performance issues.
• Proficient computer skills, including Microsoft Word and Excel.
• Strong written and verbal communication skills, including communication with direct management and engineering.
• Ability to read, analyze, and interpret scientific and technical journals and documentation.
• Ability to work with mathematical concepts including probability, statistical inference, plane and solid geometry, trigonometry, ratios, and proportions.
• Strong reasoning ability to define problems, collect data, establish facts, and draw valid conclusions.
• Ability to interpret complex technical instructions presented in mathematical or diagram form and work with multiple variables.

Work is performed in a clean‑room manufacturing environment. Requires compliance with defined gowning and contamination‑control protocols. Involves use of optical test equipment and interaction with sensitive optical assemblies. Requires sustained visual focus and attention to detail. May involve extended periods of sitting or standing.

Compensation range: $48,000 – $72,000, depending on experience. Eligible for a performance‑based bonus plan.

Health benefits, 401(k) retirement savings program with company match, PTO, and more. Full benefits information is available at
