• Demonstrated proficiency with GD&T per ANSI Y14.5, including tolerance interpretation and calculations
• Hands-on experience operating and programming Coordinate Measuring Machines (CMMs); experience with CMM Manager software (preferred)
• Familiarity with AS9100 and ISO 9001 Quality Management Systems

Knowledge

• Advanced Metrology – Skilled in the use of micrometers, calipers, height gauges, thread gauges, and advanced measurement tools
• CMM Operation & Programming – Experience operating and programming Coordinate Measuring Machines (CMMs), including DCC-based systems; familiarity with CMM Manager software (preferred)
• Drawing Interpretation & GD&T – Deep understanding of engineering drawings, tolerance stacks, and geometric dimensioning per ANSI Y14.5
• Inspection Planning – Ability to interpret quality requirements, develop inspection methods, and perform first article, in-process, and final inspections
• Molded Part Inspection – Understanding of dimensional inspection practices for molded components in addition to machined parts
• Quality Systems – Working knowledge of AS9100 and ISO 9001 quality standards, internal auditing, QMS documentation, and management review processes
• Calibration Systems – Understanding of calibration schedules, traceability requirements, and proper handling of inspection equipment
• Nonconformance Handling – Familiar with root cause analysis, deviation documentation, and participation in corrective and preventive action processes

Skills

• Proficient in manual inspection using micrometers, calipers, gauges, and height measurement tools
• Skilled in operating and programming CMMs for dimensional verification of complex parts
• Strong blueprint reading with expert-level GD&T interpretation and tolerance stack analysis
• Able to conduct thorough first article, in-process, and final inspections with minimal oversight
• Competent in generating and documenting non-conformances, deviations, and inspection reports
• Effective written and verbal communication across departments, including Quality, Production, and Engineering
• Proficient in Microsoft Office (Word, Excel); capable of maintaining digital inspection logs and audit documentation
• Strong organizational and recordkeeping skills to support traceability and compliance
• Capable of working independently and leading by example in a collaborative team environment
