Responsibilities

Own quality planning for new products and significant design or process changes, defining deliverables, owners, milestones, and acceptance criteria through production launch.
Translate customer and product requirements into critical quality characteristics, inspection criteria, and test requirements with Engineering and Manufacturing.
Participate in design failure mode and effects analysis (DFMEA), facilitate process FMEA (PFMEA), and drive closure of prioritized risk-reduction actions.
Develop or coordinate control plans, first-article inspection, measurement system assessments, and process capability studies appropriate to product and process risk.
Lead quality activities for prototype and pilot builds; evaluate defects, first-pass yield, test coverage, and process consistency, and drive readiness actions.
Partner with Supplier Quality and Supply Chain to confirm new or changed purchased parts meet qualification and first-article requirements before production ramp.
Present quality and reliability evidence at production readiness reviews; confirm verification and validation are complete, escalate open risks, and recommend release through established approval processes.
Support production handoff and early production monitoring; confirm controlled documentation, training, traceability, and ownership of remaining actions, and update controls based on launch lessons.
Establish reliability targets and qualification criteria with Engineering based on application requirements, operating conditions, and known failure mechanisms.
Plan and coordinate reliability testing, including environmental and accelerated life testing where appropriate; evaluate results and verify corrective actions through retesting.
Analyze field returns, warranty claims, manufacturing defects, and test data to identify failure trends and prioritize improvement projects.
Lead cross-functional failure investigations and structured problem solving; drive containment, root-cause confirmation, corrective and preventive actions, and effectiveness verification.
Maintain failure records, reliability metrics, and lessons learned; communicate significant risks and progress to leadership and incorporate findings into new designs and quality controls.
Mentor engineers and technical personnel in reliability methods and structured problem solving, and recommend test resources for assigned programs.
Perform targeted component-level troubleshooting on prototypes, production failures, and field returns using schematics and electronic test equipment.
Reproduce symptoms, isolate faults, and document measurements under established electrical safety and ESD controls; coordinate advanced circuit analysis with Design Engineering.
