- Manage field quality issues, including failure investigations, customer communication, and timely closure of corrective actions.
- Collaborate with manufacturing and engineering to drive system wide quality initiatives to meet quality and reliability objectives.
- Interpret and implement customer and program-specific quality flowdowns, ensuring compliance across internal teams and suppliers.
- Support internal and external audits and inspections from customers, regulatory bodies, and certification agencies.
- Develop, implement, and maintain product quality metrics (e.g., yield, defect rates, escapes, field returns), including dashboards and trend analysis.
- Support and lead product qualification, first article inspection (FAI), and verification/validation efforts with test engineering.
- Review and analyze test data, inspection reports, and non-conformance reports to ensure product integrity.
- Prepare quality reports, metrics, and presentations for leadership and customers as needed.
