The Principal Quality Engineer serves as a recognized technical expert responsible for advancing product quality, manufacturing capability, process improvement, and process performance across multiple product lines. This role applies advanced quality engineering principles, statistical methods, and structured problem‑solving techniques to develop robust manufacturing processes, improve product reliability, optimize operational efficiency, and drive continuous improvement throughout the product lifecycle.

Serve as the technical expert for complex product, process, and supplier quality issues across multiple product platforms. Lead the resolution of complex quality issues using advanced structured problem‑solving methodologies and cross‑functional collaboration to drive sustainable process improvements. Lead continuous improvement of quality control testing, defect detection, defect prevention activities, and manufacturing processes. Design, develop, validate, and optimize complex manufacturing and quality processes to improve product quality, increase operational efficiency, and process capability.

Apply advanced quality engineering tools including Design of Experiments (DOE), Statistical Process Control (SPC), Measurement System Analysis (MSA), process capability analysis, PFMEA, control plans, and root cause analysis. Analyze quality trends, process variation, and manufacturing data to identify systemic issues and implement sustainable corrective and preventive actions that improve process performance. Mentor and provide technical guidance to Quality Engineers, Quality Inspectors, and Quality Analysts in quality engineering principles, Lean methodologies, and process improvement activities.

Communicate effectively and collaborate cross‑functionally with Engineering, Manufacturing, Global Procurement & Supply Chain (GPSC), Sales, Contracts, Suppliers, and Operations to resolve complex quality‑related issues, streamline processes, and improve operational performance. Serve as a subject matter expert across multiple product platforms, providing technical guidance and support. Facilitate quality forums by providing business impact assessments, risk evaluations, and data‑driven recommendations to improve first‑pass yield, reduce defects per unit, improve process efficiency, and achieve strategic quality objectives.

Identify and implement Lean Manufacturing and Six Sigma improvement initiatives to eliminate waste and improve process capability. Lead defect reduction, process improvement, and system improvement projects using data‑driven analysis, advanced problem‑solving methods, and cross‑functional collaboration to improve quality, cost, and delivery performance. Perform advanced process capability studies, statistical analyses, and process validation activities for internal manufacturing operations and external suppliers.

Design and improve process inputs to achieve desired manufacturing and quality outcomes while reducing process variation. Establish robust process controls and control plans to sustain improvements and prevent process backsliding. Analyze manufacturing process constraints and develop standards to…
