CM Quality Engineer - Assembly

Job Title

CM Quality Engineer - Assembly

Role Summary

The CM Quality Engineer manages product quality and manufacturing execution for assigned optical modules and components at contract manufacturers. The role partners with Quality, R&D, NPI, Process Engineering and CM teams to monitor performance, resolve issues, implement changes, and support production stability.

Reports to the CM Quality Manager and provides data-driven updates on risks, actions and results.

Experience Level

Mid-level - typically requires 5+ years of experience in quality, manufacturing, process, NPI, or product engineering within optical, photonic, optoelectronic, semiconductor, or electronics manufacturing.

Responsibilities

Key responsibilities include ownership of product quality at the CM, cross-functional coordination, structured problem solving, and support for NPI and production ramp.

• Own day-to-day quality performance at the CM: defect prevention, containment, corrective actions, and quality-risk management.
• Translate product requirements into practical quality controls, critical-to-quality characteristics, specifications, acceptance criteria, inspection methods, and reaction plans.
• Analyze product quality data, defects, yield loss, test results, and customer/internal feedback to identify trends and prioritize actions.
• Collaborate with CM Quality and Engineering to monitor and improve assembly and test processes (alignment, laser/detector attach, die/wire bonding, fiber handling, epoxy dispensing/curing, soldering, cleaning, optical/electrical testing, calibration, screening, inspection).
• Coordinate regular product and process reviews with clear owners, due dates, technical evidence, and effective closure.
• Lead containment and structured problem solving for complaints, product escapes, production defects and audit findings using methods such as 8D, 5-Why, fishbone analysis, SPC, DOE, and fault-tree analysis.
• Verify corrective-action effectiveness and ensure lessons learned are incorporated into control plans, PFMEA, work instructions, inspection criteria, and training.
• Support NPI, product qualification, manufacturing transfer, process validation, engineering changes, and production ramp activities.
• Track and report KPIs (first-pass yield, defect rate, DPPM, customer complaints, corrective-action aging, process capability) and lead data-driven improvement projects.
• Maintain effective communication between Lumentum and the CM on requirements, process risks, deviations and performance; occasional travel and off-hours support may be required.

Requirements

Must-have skills and experience. Education requirements are listed separately below.

• Typically 5+ years experience in quality, manufacturing, process, NPI, or product engineering in optical, photonic, optoelectronic, semiconductor, or electronics manufacturing.
• Experience working with contract manufacturers and cross-functional teams to resolve product and process quality issues.
• Working knowledge of optical module/component products, assembly processes, optical/electrical testing, reliability requirements, and manufacturing quality controls.
• Practical experience with quality tools: control plans, PFMEA, SPC, process capability, MSA, 8D, CAPA, and engineering-change management.
• Strong analytical, coordination, follow-through and structured problem-solving skills; able to communicate effectively in English.
• Familiarity with KPI analysis (Pareto), data-driven prioritization, and continuous-improvement methods.
• Ability to work in cleanrooms and manufacturing-floor environments and interact with global teams.

Education Requirements

Bachelor's degree in Optical Engineering, Optoelectronics, Electrical Engineering, Mechanical Engineering, Manufacturing Engineering, Quality Engineering, or a related field.
