Quality Engineer - Assembly

About the role

This role focuses on quality execution and partnership with assigned contract manufacturers, ensuring optical product and process quality standards are met. You will own day-to-day quality performance, lead quality reviews, and translate Lumentum product requirements into clear quality standards and acceptance criteria for optical modules, components, and optoelectronic assemblies. You will govern assembly and test processes, drive cross-functional problem solving, and manage quality KPIs and performance metrics.

Key responsibilities

• Execute the CM quality strategy, standards, operating rhythm, and escalation model established by the CM Quality organization for the assigned contract manufacturer
• Own day-to-day quality performance for the assigned CM, maintaining clear ownership across the CM, R&D, NPI, Supply Chain, Reliability, and Customer Quality teams
• Lead regular quality reviews with the assigned CM management team and internal stakeholders; communicate risks, decisions, resource needs, and recovery plans using concise, data-based recommendations
• Translate Lumentum product requirements into clear quality standards, critical-to-quality characteristics, specifications, and acceptance criteria for optical modules, optical components, and optoelectronic assemblies
• Govern the assigned CM's assembly and test processes, including active and passive alignment, laser or detector attach, die and wire bonding, fiber handling, epoxy dispensing and curing, soldering, cleaning, optical and electrical testing, calibration, screening, and final inspection
• Own the cross-functional response to customer complaints, escapes, returns, audit findings, and major internal quality issues; coordinate containment, root-cause analysis, corrective action, verification, and closure
• Lead structured problem solving using 8D, 5-Why, fishbone, fault-tree, DOE, SPC, and other appropriate methods; ensure actions address systemic causes and are sustained at the CM
• Execute the CM quality KPI framework, including customer PPM/defect rate, first-pass yield, rolled throughput yield, DPPM, complaint closure, audit action aging, CAPA effectiveness, and process capability
• Use data analysis to prioritize the largest risks and opportunities, quantify business impact, and report progress to CM and internal management team
• Drive continuous-improvement projects that improve quality, yield, reliability, delivery stability, and total cost
