• Lead and develop Principal Manufacturing Technicians across distributed sites. • Drive consistent interpretation and application of manufacturing quality standards across locations. • Define and maintain manufacturing quality rubrics that translate expert judgment into objective, auditable criteria. • Convert clinician feedback (returns, remakes, qualitative notes) into quantitative specifications and CTQs (Critical to Quality). • Align manufacturing rubrics with design rubrics in partnership with the Manager of Design Quality. • Lead Attribute Agreement Analysis (AAA) and calibration programs for inspection consistency. • Establish SPC/control charts and action thresholds for key CTQs. • Apply Lean Six Sigma methods to reduce variation and improve FPY. • Partner with the Automation team to ensure end-of-line 3DQC measures the correct attributes and thresholds defined by Principal Technicians. • Validate 3DQC performance (repeatability, drift, coverage) and ensure data is used for upstream improvement, not just sorting. • Build and operate a Red Rabbits (golden cases / known-defect sets) program to verify that human and automated QC reliably detect critical defects. • Use Red Rabbits to detect drift, trigger retraining, and validate changes. • Run DOEs to resolve spec disputes, validate changes, and improve process capability. • Define certification and re-certification requirements for manufacturing and QC roles. • Support audit readiness through clear standards, evidence, and sustained compliance.
