Principal Quality Engineer

Responsibilities

• New Product Introduction (NPI): Partner with design, package, and manufacturing teams during NPI to define quality gates, review FMEAs (Design & Process), establish control plans, and ensure product meets qualification and reliability requirements prior to production ramp.
• Process Quality & Control: Develop, document, and implement in-process quality controls including Statistical Process Control (SPC), measurement system analysis (MSA), and go/no-go checkpoints to monitor and improve yield and defect rates across manufacturing operations.
• Supplier Quality: Support supplier quality activities including conducting supplier audits, tracking supplier scorecards, issuing Supplier Corrective Action Requests (SCARs), and monitoring incoming quality for key semiconductor and substrate suppliers.
• Quality Management System (QMS): Contribute to the maintenance and continuous improvement of the ISO 9001 QMS; author and review procedures, work instructions, and audit reports to ensure alignment across the organization.
• Data Analysis & Metrics: Define, track, and report key quality KPIs (PPM, DPMO, warranty cost, MTBF, supplier defect rates) to engineering and operations leadership; leverage data-driven insights to prioritize quality improvement efforts.
• Cross-Functional Collaboration: Serve as the quality engineering point of contact across design, validation, operations, and customer-facing teams; support Field Application Engineers (FAEs) with technical quality information and ensure customer issues are driven to resolution.
• Quality Improvement: Apply Lean, Six Sigma, and other quality improvement methodologies to identify and eliminate waste, reduce variation, and improve overall product reliability and yield.
