Perform first article, in-process, and final inspections of precision CNC-machined aerospace components.
Conduct detailed dimensional inspections using CMMs and handheld precision measuring instruments.
Utilize micrometers, calipers, height gauges, bore gauges, indicators, optical comparators, and other inspection equipment.
Read and interpret complex engineering drawings, blueprints, and Geometric Dimensioning & Tolerancing (GD&T) requirements.
Complete and maintain inspection records, quality reports, and traceability documentation in accordance with AS9100 quality management standards.
Support First Article Inspection Reports (FAIRs) in accordance with AS9102 requirements.
Verify machined components meet customer specifications, engineering requirements, and established tolerances.
Identify, document, and communicate nonconforming materials and dimensional discrepancies.
Collaborate with CNC machinists, manufacturing engineers, and quality personnel to troubleshoot inspection issues and resolve quality concerns.
Maintain accurate inspection records and ensure compliance with internal procedures and customer requirements.
Support continuous improvement initiatives aimed at reducing defects and improving manufacturing quality.
Previous quality inspection experience within an aerospace, defense, or high-precision CNC machining environment.
Strong hands-on experience with dimensional inspection of CNC-milled and CNC-turned components.
Experience operating CMM equipment; programming experience is a plus.
Proficiency with handheld precision measurement tools, including micrometers, calipers, bore gauges, and height gauges.
Strong understanding of engineering drawings, GD&T, and dimensional tolerancing.
Familiarity with AS9100 quality systems, inspection documentation, and aerospace traceability requirements.
Experience completing first article, in-process, and final inspection documentation.
Ability to identify dimensional nonconformances and communicate findings effectively.
Strong attention to detail, organizational skills, and ability to work independently in a fast-paced manufacturing environment.
Experience with CMM software such as PC-DMIS, ZEISS CALYPSO, or similar platforms.
Familiarity with AS9102 First Article Inspection requirements.
Experience inspecting complex aerospace gears, shafts, housings, and other tight-tolerance machined components.
Knowledge of ISO 9001, AS9100, and aerospace customer quality requirements.
Experience with inspection equipment calibration, nonconformance reporting, and corrective action processes.
This is an excellent opportunity to join an established aerospace manufacturer with advanced CNC machining capabilities, a strong commitment to quality, and a long-standing presence in the precision manufacturing industry.
