## Description

Introduction to the job The Advanced Processing Optical Cleaning Engineer will support the cleaning and preparation of precision optical components. This is a 2nd shift, hands-on engineering role with significant time spent working directly with optical components, cleaning equipment, chemicals, technicians, and production processes. The engineer will support daily manufacturing, execute cleaning test plans, troubleshoot process issues, and implement practical improvements to reduce contamination and defects. This role is ideal for an engineer who enjoys hands-on work and wants to develop expertise in optical cleaning and contamination control. Role and responsibilities Shift Details: Monday through Friday 2:00PM - 10:30PM Support manual, chemical, ultrasonic, and automated cleaning processes for precision optical components. Prepare and evaluate optical surfaces before optical coating, including identification of particles, stains, residues, and other surface quality imperfections. Work directly with technicians to troubleshoot cleaning, handling, equipment, and contamination issues during 2nd shift production. Execute engineering experiments, cleaning trials, and qualification activities to evaluate chemicals, process parameters, and cleaning methods. Collect and analyze process data to identify trends, variation, and opportunities for improvement. Participate in root-cause investigations involving cleaning, contamination, handling, and coating defects. Support cleaning and contamination measurement equipment, including troubleshooting, qualification, and process improvements. Develop and maintain work instructions, test plans, process specifications, and qualification documentation. Train and support technicians on cleaning processes and process changes.
