Optical Process Engineer - MEMS & Optical Modules

Molex; Fremont (CA); On-site; USD 105,000 - 145,000; Full time

Job summary

Molex is seeking an Optical Process Engineer to develop and optimize manufacturing processes for cutting-edge fiber optic MEMS-based Optical Circuit Switch products used in AI clusters and data centers. The role spans lab work, process development, and production support across cross-functional teams.

You will work hands-on in the lab, improve process yield, implement DOE studies, and help scale production for high-volume manufacturing while collaborating with suppliers and R&D across sites.

Qualifications

• Bachelor's degree in Optical Engineering, Mechanical Engineering, Electrical Engineering, Materials Science, Physics, or related field.
• Internship or career experience in manufacturing, test, or process engineering with electro-optical products.
• Familiarity with reliability testing and environmental qualification protocols.
• Familiar with opto-mechanics and basic electronics.
• Experience working in a lab with equipment.
• Experience with statistical analysis and data analysis.
• Knowledge/Experience with glass, ceramic, metallic materials, and optical adhesives.
• Excellent problem-solving, documentation, and cross-functional communication skills.
• Willingness to work in a cleanroom environment and follow ESD/contamination protocols.

Responsibilities

• Develop and maintain manufacturing processes for optical modules, including fiber handling, alignment, testing, integration.
• Conduct DOE and statistical analyses to optimize process parameters, reduce variation, and improve yield and throughput.
• Collaborate with mechanical engineers to design, develop, and validate fixtures and assembly tools to ensure process repeatability and manufacturability.
• Create and manage process and quality documentation (Work Instructions, process flows, SOPs, ECOs, etc.).
• Investigate in-process failures to determine root cause, implement and verify corrective actions.
• Work with reliability engineering to run reliability tests and drive design/process improvements.
• Support production transfer and ramp up for high volume manufacturing.
• Provide technical support to manufacturing, quality, and supplychain teams.
