• Plan and perform Measurement System Analysis (MSA), including Gauge R&R, bias, linearity, stability, resolution, and attribute agreement studies as applicable.
• Support material, tooling, mold, machine, equipment, and process validation through Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ), including protocols, acceptance criteria, testing, deviation resolution, and documentation.
• Analyze manufacturing and quality data to identify variation and opportunities to reduce scrap, rework, complaints, and cost of poor quality.

• Hands-on experience with root-cause analysis, CAPA, PFMEA, control plans, SPC, process capability analysis, and measurement systems analysis.
• Experience performing Gauge R&R studies and interpreting capability and performance metrics (Cp, Cpk, Pp, Ppk).
• Working knowledge of IQ/OQ/PQ validation, risk-based sampling, test methods, acceptance criteria, and technical documentation.
• Strong analytical, communication, cross-functional collaboration, and problem-solving skills; proficiency in Microsoft Excel.
