Core Responsibilities

Primary Functions

Lead cross-functional root cause analyses (5 Whys, Ishikawa, Fishbone, and Fault Tree Analysis) for recurring production defects and implement robust corrective and preventive actions (CAPA) that reduce defect rates and prevent recurrence.
Develop, maintain, and optimize production control plans, process flow diagrams, work instructions, and standard operating procedures (SOPs) to ensure consistent product quality and compliance with customer and regulatory requirements.
Plan and execute APQP (Advanced Product Quality Planning) and PPAP (Production Part Approval Process) activities for new product launches and engineering changes, including creation and approval of PFMEA/DFMEA outputs, control plans, and validation evidence.
Design and implement statistical process control (SPC) strategies and real-time process monitoring to detect process drift, reduce process variability, and drive measurable improvements in yield and scrap reduction.
Conduct Measurement System Analysis (MSA) including Gage R&R studies, bias, linearity, and stability assessments to validate inspection systems and ensure data integrity for quality decisions.
Lead or support internal and external quality audits (ISO 9001, IATF 16949, customer audits) and close nonconformances by driving corrective actions, root cause verification, and evidence-based verification of effectiveness.
Work directly on the production floor to troubleshoot process issues, support production runs, and implement containment plans (100% inspection, sorting, temporary tooling) while permanent corrective actions are developed.
Collaborate with manufacturing, engineering, procurement, and R&D to implement Design for Manufacturability (DFM) and Design for Quality (DFQ) improvements that reduce complexity, cost, and defect risk.
Manage supplier quality performance through supplier qualification, periodic supplier audits, supplier corrective action requests (SCARs), and ongoing performance metrics (PPM, on-time delivery, process capability).
Use Six Sigma tools (DMAIC), Lean methodologies, and statistical software (Minitab, JMP, Python/pandas) to analyze data, create experiments (DOE), and provide data-driven recommendations for process improvements.
Establish and maintain product acceptance criteria, inspection plans, sampling plans (ANSI/ASQ Z1.4), and final inspection protocols to ensure shipment of conforming product.
Drive and document continuous improvement projects focused on scrap reduction, cycle time reduction, yield improvement, and cost of poor quality (COPQ) reduction, reporting ROI and measured impact.
Validate and qualify production processes, equipment, and new tooling (IQ/OQ/PQ where applicable), ensuring transferred processes meet capability and quality targets before full production ramp.
Coordinate failure analysis and returned material investigations (RMA), including laboratory testing, non-destructive testing (NDT), metallurgical analysis, and detailed failure modes documentation to inform corrective actions.
Implement and maintain traceability systems and lot control for raw materials and finished goods to support containment, recalls, and root cause investigations when required.
Prepare and present quality metrics, scorecards, and trend analysis to plant leadership and stakeholders, translating technical findings into actionable business decisions and improvement roadmaps.
Create and deliver training programs for operators and inspectors on inspection techniques, critical dimensions, new procedures, and quality awareness; mentor team members in problem-solving tools.
Review engineering change orders (ECOs) and material change notifications (MCNs) to assess potential quality impacts, update quality documentation, and lead risk assessments prior to authorization.
Maintain compliance with customer-specific requirements, quality agreements, and regulatory standards; act as point of contact for customer quality issues and coordinate timely responses.
Implement containment & rework strategies and coordinate cross-functional efforts to return impacted inventory to conformity while minimizing customer impact and financial exposure.
Monitor and improve process capability indices (Cp, Cpk) through targeted process improvements, tooling adjustments, machine maintenance, and supplier development activities.
Facilitate cross-site standardization and best practice sharing for quality processes, tooling, and inspection methods to drive consistency across multiple manufacturing locations.

Secondary Functions

Support continuous improvement initiatives by participating in Kaizen events, value stream mapping, and root cause elimination projects that impact product quality and throughput.
Assist in development and maintenance of electronic quality records and PLM/ERP quality modules (e.g., SAP QM, Oracle) to ensure accurate traceability and audit readiness.
Provide technical support for New Product Introduction (NPI) projects, including risk assessments, pilot builds, and initial capability studies to confirm manufacturing readiness.
Participate in capital equipment purchases and qualification by providing quality requirements, acceptance tests, and test protocols to ensure new equipment meets process needs.
Support sustainability and environmental initiatives by recommending processes and materials that reduce waste, rework, and regulatory risk associated with nonconforming product.
Maintain calibration program oversight for inspection and test equipment in partnership with metrology/calibration teams to ensure measurement accuracy.
Contribute to supplier development programs by coaching suppliers on quality systems, SPC, FMEA, and corrective action effectiveness to elevate upstream quality.
Serve as backup point of contact for emergency quality issues during off-hours and support incident response until resolution and root cause verification.
