CNC Machine Shop Quality Inspector

Quality Control Technician

Trimen Industrial LLC — Belgium, WI Full-time | 1st shift to start — must be open to moving to 2nd shift Pay: $16-$25/hr, based on experience.

About Trimen

Trimen Industrial is an ISO 9001:2015 certified precision CNC job shop in Belgium, WI, running roughly 30 machines — horizontal mills, vertical mills (3, 4, and 5 axis), and lathes — in a 56,000 sq ft facility. We machine tight-tolerance aluminum and steel components for aerospace, defense, medical, agriculture, and industrial customers, with in-house machined tolerances down to 0.003 in. and finer ground features (±0.0005 in. and tighter) completed through qualified outside grinding partners. High mix, low-to-medium volume — no two days on the inspection bench look the same.

The Role

You are the last set of eyes before a part leaves the building, and the first set of eyes when something looks wrong on the floor. You'll measure everything we make, program and run our Zeiss CMM, build and submit PPAP packages, and work shoulder-to-shoulder with our CNC setup technicians so problems get caught at the machine instead of at final inspection.

Where you fit: You'll report to our QC Manager and work alongside a junior QC assistant in our temperature-controlled inspection lab but not limited to the lab, also will be on the floor. You start on 1st shift working directly under the manager; as you come up to speed, this role may transition to 2nd shift, where you would be the go-to quality inspector on the floor for that shift, with the QC Manager's support during overlap. Candidates open to 2nd shift will be strongly preferred.

This is a hands-on floor role, not a desk job. You'll be at the CMM, at the comparator, at the surface plate, and out at the machines on the shop floor.

What You'll Do

Measurement and Inspection

• Perform first article, in-process, and final inspection across a wide mix of part numbers
• Program, run, and maintain inspection routines on our Zeiss CMM (CALYPSO) — build repeatable alignments and fixturing for recurring jobs
• Run the optical comparator for profile, radii, small features, and thread forms
• Work fluently with the full gage set: micrometers, calipers, height gages, bore gages, pin gages, indicators, depth mics, radius and thread gages, surface finish comparators
• Measure threads correctly and completely — thread plug and ring gages, thread micrometers, three-wire pitch diameter, functional versus pitch diameter acceptance on both internal and external threads
• Know when a feature calls for the CMM, when it calls for the comparator, and when hand gaging is the right answer

GD&T

• Read and apply GD&T per ASME Y14.5 in daily practice — true position, profile, runout, concentricity, datum structures, MMC/LMC and bonus tolerance
• Balloon prints and build inspection reports that map cleanly back to the drawing
• Translate GD&T callouts into practical, repeatable measurement methods on the floor

PPAP and Documentation

• Build and submit complete PPAP packages: dimensional results, material and process certifications, control plans, process flow, measurement system analysis (gage R&R), capability studies (Cpk/Ppk), and the Part Submission Warrant
• Maintain inspection records and quality data in our ERP and shop-floor tablet system so traceability holds up under audit
• Write clear inspection reports, NCRs, and customer-facing corrective action responses

Working With Setup and Production

• Coordinate directly with CNC setup technicians to define what gets checked on each job, how often, and with what gaging
• Build check sheets, in-process inspection plans, and control plans for new work as it comes in
• Approve first pieces and get setups released quickly without cutting corners
• Train and coach setup techs and operators on gaging technique, print interpretation, and when to stop and ask
• Catch process drift before it becomes scrap — you'll have the standing to shut a job down

Quality System

• Support and maintain our ISO 9001:2015 quality management system
• Write and manage nonconformance reports; contain and segregate suspect material
• Support root-cause investigations and corrective actions under the QC Manager
• Perform receiving inspection on raw material and outside processes (grinding, heat treat, plating, anodize, coating) and verify certifications against the PO
• Maintain the gage calibration program: schedule, tag, record, and pull anything out of calibration
• Support internal audits and third-party surveillance audits

What You Need

• 5+ years of quality/inspection experience in a CNC machining environment — this is a firm requirement, not a preference
• Demonstrated CMM programming ability; Zeiss/CALYPSO strongly preferred, but PC-DMIS, Mitutoyo, or comparable experience with a willingness to cross-train will be considered
• Hands-on proficiency with optical comparators and the full range of precision hand gaging
• Working command of GD&T per ASME Y14.5 — applied daily, not just trained on once
• Proven thread measurement and acceptance experience across internal and external threads
• Experience building and submitting PPAP packages
• Strong blueprint reading on complex, multi-datum machined parts
• Clear written communication — you'll be writing NCRs, inspection reports, and customer corrective actions
• Computer literate and comfortable working in an ERP and on tablet-based shop-floor systems
• Willingness to move to 2nd shift as the role develops
• The backbone to hold a line on a part that isn't right, even when the ship date is tomorrow

Nice to Have

• ASQ certification (CQT, CQI, or CMI) — a plus, not required
• CMM programming directly from CAD models
• Gage R&R and capability study experience beyond PPAP submissions
• Internal auditor training (ISO 9001)
• Experience with inspection of ground, plated, and coated features
• Experience writing control plans and inspection methods from scratch for new part numbers

Who You're Not

• Someone who signs off on a first article to keep a job moving
• Someone who finds a problem and stays quiet about it
• Someone who wants inspection to be a paperwork exercise disconnected from the floor

Our Hiring Process

We move fast and we respect your time:

• Video interview — a conversation about your background and experience
• In-person visit — shop tour, meet the QC Manager, and a hands-on inspection assessment: measure a sample part, interpret a print, and verify a thread
• Offer decision

The practical assessment isn't a trick — if you've done this work for five years, you'll be comfortable. It's how we make sure the shop floor respects your signoff from day one.

Why Trimen
