Conduct comprehensive calibration, verification, and maintenance of measurement equipment, fixtures, and master gauges in accordance with ISO/IEC 17025 and internal standards.
Generate, analyze, and present clear, concise inspection reports that document dimensional results, part conformity, deviations, and non-conformances.
Lead root cause analysis investigations for dimensional discrepancies, collaborating directly with engineering and manufacturing teams to implement effective corrective and preventive actions (CAPA).
Develop, optimize, and validate new CMM inspection programs for New Product Introduction (NPI) projects, ensuring robust and repeatable measurement strategies.
Design and execute Measurement System Analysis (MSA) studies, such as Gauge Repeatability & Reproducibility (GR&R), to qualify and monitor the performance of measurement systems.
Provide real-time dimensional feedback and technical support to production teams, enabling process control and immediate adjustments to maintain quality.
Manage and maintain all inspection records and calibration data within the organization's Quality Management System (QMS), ensuring audit readiness.
Train and mentor junior technicians, inspectors, and manufacturing personnel on the proper use of metrology equipment and the interpretation of dimensional data.

Secondary Functions

Participate in Design for Manufacturability (DFM) and inspection feasibility reviews, providing critical feedback on part tolerancing and measurement strategies.
Support supplier quality initiatives by performing incoming inspections on critical components and validating supplier-provided dimensional reports.
Act as a subject matter expert during internal and external quality audits (e.g., ISO 9001, AS9100), demonstrating metrology processes and providing necessary documentation.
Drive continuous improvement projects within the metrology lab and quality department to enhance efficiency, reduce inspection cycle times, and improve measurement accuracy.
Assist in the design, procurement, and qualification of custom inspection fixtures, gauges, and tooling to support new and existing products.
Develop and maintain Standard Operating Procedures (SOPs), work instructions, and training materials for all metrology-related activities.
Perform reverse engineering of components by capturing precise dimensional data using 3D scanning or CMM probing techniques.
Liaise with and manage external calibration service providers for specialized equipment, ensuring timely and compliant service.
