Quality Control Inspector

Launch Your Career in Precision Manufacturing

Are you passionate about precision, detail-oriented, and ready to start a rewarding career in advanced manufacturing? We're looking for Quality Control Inspectors to join our team and help ensure every component we produce meets the exacting standards required for aerospace, defense, and high-tech industries.

About This Role

As a Quality Control Inspector, you'll be the guardian of quality—ensuring that every part we manufacture meets engineering specifications and customer requirements. You'll work with precision measurement tools, coordinate measuring machines (CMM), and technical drawings to validate that components are built right the first time.

We're hiring for both Level 1 (Entry-Level) and Level 2 (Experienced) positions. Your experience, skills, and qualifications will determine your starting level—and we provide clear paths for advancement as you grow your expertise.

What You'll Do

• Inspections

• Conduct thorough manual inspections at receiving (to catch supplier issues early), in-process (to identify problems before final machining), and final stages (as the last quality gate before customer delivery).

• Perform dimensional inspections using precision metrology tools including calipers, micrometers, height gauges, thread gauges, and bore gauges to verify critical dimensions and tolerances.

• Identify and document visual defects including nicks, scratches, burrs, surface finish inconsistencies, coating defects, and contamination.

• Operate CMM (Zeiss/Calypso) to run pre-programmed inspections: load and unload parts, verify proper setup, and interpret results against engineering requirements

• Read and interpret technical drawings and GD&T to verify critical dimensions, tolerances, and geometric characteristics ensuring parts meet specifications.

• Documentation & Compliance

• Maintain accurate inspection records for all visual and dimensional findings in ProShop MES in compliance with AS9100 and ISO 9001 quality standards.

• Communicate any deviations, non-conformances, or visual defects clearly and promptly with supporting photos or documentation.

• Participate in non-conformance investigations, root cause analysis, and corrective action processes.

• Follow all Quality Manual requirements and AS9100 procedures.

• Workplace Excellence

• Maintain a clean and organized workspace following all safety procedures and using required protective equipment.

• Report safety hazards, incidents, or concerns immediately.

• Complete assigned training on time and proactively learn processes, equipment, and quality requirements.

• Collaboration & Growth

• Communicate regularly with your supervisor and team through status updates, active participation in meetings, and improvement ideas while addressing routine issues independently and escalating non-routine matters appropriately

• Work closely with machinists and engineers to clarify acceptance criteria, resolve inspection concerns, and provide real-time feedback when visual defects are detected—helping the manufacturing team understand root causes such as tooling, handling, or process issues

• Seek feedback, ask questions, and learn from experienced team members to continuously improve

• Take ownership of work quality, act with integrity, and let customer needs guide your decisions

• Collaborate on continuous improvement initiatives.

• Step into other support roles as needed based on business demands, including:

• Assisting with CNC machine operation

• Post-processing additively manufactured (3D printed) parts

• Supporting mechanical assembly operations

• Logistics tasks such as transporting components to/from outside processing vendors

• Other duties as assigned

What We're Looking For

• Required Skills & Qualifications

• Certificate or degree from a technical/trade school in machining, metrology, quality control, or related manufacturing program OR equivalent hands-on training.

• No prior quality inspection experience required—this is an entry-level role with comprehensive training provided.

• Level 2 requires at least 2 years of relevant experience.

• Ability to read and interpret technical drawings and blueprints.

• Basic understanding of GD&T (Geometric Dimensioning and Tolerancing) principles.

• Familiarity with precision measurement tools (calipers, micrometers, height gauges, etc.).

• Essential Qualities

• Exceptional attention to detail — You naturally notice the small things that ensure quality and safety

• Strong problem-solving ability — You think critically and know when to work independently vs. ask for guidance

• Dependability — Your team can count on you to show up, follow through, and deliver

• Collaborative mindset — You work well with others and communicate effectively

• Learning orientation — You're eager to develop new skills and adapt in a fast-paced environment

• Quality and safety commitment — You take pride in doing things right the first time and prioritize safety.

• Preferred Skills & Qualifications

• CMM experience with Zeiss/Calypso software

• Quality systems knowledge (SPC, FMEA, control plans)

• Quality certifications (ASQ CQI, CMM programming)

Physical Demands

• Ability to lift and move materials up to 50 lbs

• Stand, walk, and perform hands-on work for extended periods

• Work safely in industrial environments with required PPE

• Fine motor skills for handling precision components
