This role will be responsible for supplier qualification, supplier process and product quality, failure analysis, corrective actions, and continuous improvement across the semiconductor and optical component supply chain.\nKey Responsibilities\nManage supplier quality for MEMS and LCOS devices, wafers, components, assemblies, and related semiconductor materials.\nLead supplier qualification, capability assessment, and ongoing performance monitoring.\nConduct supplier process audits, product audits, and quality system assessments.\nEvaluate key semiconductor manufacturing processes, including wafer fabrication, MEMS structure formation, bonding, wafer-level packaging, dicing, assembly, optical alignment, testing, and final inspection.\nSupport LCOS-related processes, including silicon backplane, liquid crystal cell assembly, optical performance testing, contamination control, alignment, and packaging.\nReview supplier quality requirements, control plans, inspection standards, sampling plans, and acceptance criteria to ensure it is fully aligned with factory inspection.\nWork with CE to drive supplier quality activities from NPI to MP, including design review, process qualification, first article inspection, and production ramp-up.\nReview and approve supplier documentation, including PFMEA, process flow, control plan, work instructions, SPC plans, MSA studies, reliability plans, and change-control procedures.\nLead root-cause analysis and corrective actions for supplier-related issues using 8D, Fishbone, 5 Why, DOE, and other structured problem-solving methods.\nCoordinate failure analysis for electrical, mechanical, optical, reliability, contamination, yield, and performance-related issues.\nMonitor supplier quality dashboard, including yield, DPPM, customer returns, corrective-action closure, process capability, and on-time delivery.\nManage supplier change notifications and assess the impact of changes to materials, processes, equipment, tooling, software, facilities, and manufacturing sites with CCB/SPCN procss.\nSupport qualification and validation of alternative suppliers and second sources.\nEstablish and maintain supplier improvement plans for high-risk or underperforming suppliers.\nEnsure suppliers comply with applicable quality standards, customer requirements, ESD controls, contamination-control requirements, and change-management procedures.\nProvide regular quality updates, risk assessments, escalation reports, and improvement recommendations to management.\nSupport customer audits, internal audits, and cross-functional quality reviews when required.\nRequired Qualifications\nBachelor’s degree or above in Electrical Engineering, Semiconductor Engineering, Materials Science, Mechanical Engineering, Optics, Physics, or a related discipline.\n10+ years of experience in semiconductor quality, supplier quality, wafer manufacturing, optical components, or advanced packaging.\nExperience working with semiconductor suppliers, wafer fabs, OSATs, MEMS manufacturers, optical component suppliers, or display-related suppliers.\nStrong knowledge of semiconductor manufacturing processes, quality systems, and supplier management practices.\nHands-on experience with root-cause analysis, 8D, CAPA, SPC, MSA, FMEA, control plans, and process capability analysis.\nAbility to interpret engineering drawings, specifications, test data, process data, and reliability reports.\nExperience with supplier audits and process qualification.\nStrong communication, negotiation, project management, and problem-solving skills.\nAbility to work independently and effectively in a cross-functional and international environment.\nWillingness to travel to supplier sites as required.\nFluent written and spoken English.\nPreferred Qualifications\nExperience with MEMS, LCOS cell, or related optical electro products.\nKnowledge of wafer-level packaging,
