Process Engineer

Primary Duties & Responsibilities

• Lead process industrialization for optics fabrication (polishing, grinding, coating, cleaning, and metrology) to support production ramp-up.
• Transfer processes from development or pilot lines into high-volume manufacturing with stable yield and throughput.
• Define and optimize process parameters, tooling, fixtures, and equipment settings to meet optical performance and quality requirements.
• Develop and release manufacturing documentation including process flows, work instructions, control plans, and PFMEA.
• Establish process controls, SPC, and monitoring systems to ensure repeatability and defect reduction.
• Drive yield improvement, cycle time reduction, and cost optimization through data-driven root cause analysis.
• Support equipment qualification, acceptance, and process capability studies (IQ/OQ/PQ, Cp/Cpk).
• Collaborate closely with R&D, Quality, Equipment, and Production teams during ramp-up and ongoing operations.
• Lead troubleshooting of process excursions and nonconformances, implementing corrective and preventive actions.
• Support training of operators and technicians during process deployment and scale-up.

Education & Experience

• Bachelor's degree in Optical Engineering, Physics, Materials Science, Mechanical Engineering, Industrial Engineering, or a related engineering discipline.
• 3–7 years of experience in optics fabrication or precision manufacturing, with hands-on involvement in process industrialization and production ramp-up.
• Demonstrated experience transferring processes from development/pilot to volume manufacturing.
• Strong background in process optimization, capacity planning, line balancing, and workflow design (Industrial Engineering focus).
• Experience with statistical process control (SPC), process capability analysis (Cp/Cpk), PFMEA, and root cause analysis.
• Familiarity with optics manufacturing processes such as grinding, polishing, coating, cleaning, and optical metrology is highly preferred.
• Experience working in a high-mix, low-to-medium volume or scaling manufacturing environment.
• Ability to work cross-functionally with R&D, Quality, Equipment, and Operations teams during ramp-up phases.
