• Verify material certifications; establish supplier qualification, monitoring, corrective-action, and containment processes
• Ensure traceability and disposition tracking.
• Develop and implement in-process quality control systems, containment and escalation processes for quality excursions, and process controls across manufacturing operations
• Monitor process performance and quality trends
• Drive reduction of defects, scrap, rework, and quality escapes; and ensure consistent quality practices across both fabs.
• Implement and maintain manufacturing quality systems, including Statistical Process Control (SPC), CAPA, Non-Conforming Material Report (NCMR) processes, FMEA, and process control plans
• Provide independent quality review and approval of Engineering Change Notices (ECNs), process changes, and manufacturing transfers
• Establish and maintain ESD control programs and quality documentation and records.
• Lead investigations of manufacturing quality excursions and process escapes in partnership with Process Engineering and Product Engineering
• Monitor process capability (Cp/Cpk)
• Provide quality leadership for measurement-system capability and MSA activities
• Support tool and process qualification and requalification
• Use quality data to improve process stability, defect reduction, and yield.
• Maintain audit readiness across both fabrication facilities
• Support internal, customer, and ISO audits
• Support contamination-control initiatives and cleanroom environmental monitoring
• Ensure quality documentation meets compliance requirements
• Partner with the Sr. Manager, Photonics Quality Engineering on corporate quality initiatives and enterprise quality alignment.
• Other relevant tasks, as assigned.
