Position Summary

The CMM Operator is an experienced metrology technician responsible for independently setting up, operating, and maintaining Coordinate Measuring Machine (CMM) equipment to perform dimensional inspections on automotive components, sub-assemblies, and tooling. Working with a high degree of autonomy, this role executes and modifies CMM measurement programs, leads First Article Inspection activities, interprets complex GD&T callouts, and drives corrective action through data analysis. The mid-level CMM Operator serves as a technical resource for production and quality teams and may provide guidance to junior operators.

Key Responsibilities

• Independently set up, operate, calibrate, and perform routine maintenance on CMM equipment (PC-DMIS, Calypso, or equivalent)
• Create, modify, and optimize CMM measurement programs from engineering drawings and CAD models
• Execute First Article Inspections (FAI) per AS9102 / PPAP requirements and compile dimensional reports
• Interpret complex engineering drawings, GD&T callouts (ASME Y14.5), and customer-specific tolerances
• Perform Measurement System Analysis (MSA) including Gage R&R studies to validate measurement processes
• Analyze dimensional data using SPC tools; identify trends, out-of-control conditions, and support process improvement
• Initiate and support Non-Conformance Reports (NCRs), Corrective Action Reports (CARs), and 8D problem-solving
• Collaborate with Manufacturing, Engineering, and Supplier Quality on root cause analysis and disposition of non-conforming parts
• Maintain calibration records and ensure all measurement equipment is within calibration schedules
• Support production launch activities including APQP, control plan development, and gauge studies
• Mentor and provide on-the-job guidance to entry-level CMM operators and quality technicians
• Maintain accurate inspection records in the QMS and generate dimensional summary reports for internal and customer use

Required Qualifications

• High school diploma or GED required; Associate degree or technical certificate in Metrology, Manufacturing Technology, or Quality preferred
• 2–5 years of hands-on CMM operation experience in an automotive or precision manufacturing environment
• Proficiency with CMM software — PC-DMIS, Calypso, or equivalent; ability to write and edit measurement programs
• Strong working knowledge of GD&T per ASME Y14.5 and ability to interpret complex engineering drawings
• Demonstrated experience with PPAP, APQP, MSA, SPC, and IATF 16949 quality systems
• Proficiency with hand measurement tools: calipers, micrometers, CMM touch probes, surface plates
• Ability to work independently, prioritize multiple open jobs, and meet inspection deadlines
• Computer proficiency including MS Office (Excel, Word); experience with QMS/ERP systems (SAP, Plex, or similar)

Preferred Qualifications

• Experience with offline CMM programming from CAD models (CATIA, SolidWorks, or similar)
• ASQ Certified Quality Inspector (CQI) or Certified Quality Technician (CQT) certification
• Knowledge of Renishaw or Zeiss probe systems and stylus configurations
• Experience supporting customer PPAP submissions and dimensional approval packages
• Bilingual English/Spanish a plus in Inland Empire manufacturing environments

Work Environment

This position operates primarily in a temperature-controlled metrology lab and manufacturing floor environment. PPE including safety glasses and steel-toe footwear is required at all times on the production floor. Exposure to machining coolants, light oils, and metal particulate is possible. The CMM Operator may be required to work overtime, weekend shifts, or adjusted hours during production launches, customer audits, or high-volume inspection periods.

Competencies

• High analytical ability and meticulous attention to dimensional accuracy
• Self-directed with strong time management and ability to manage multiple open inspection jobs
• Clear written and verbal communication — able to present inspection findings to engineering and management
• Collaborative team approach with demonstrated ability to mentor junior staff
• Ownership mentality — takes accountability for data integrity and quality outcomes
