About the role

Quality Technician The Quality Technician ensures product compliance and material integrity throughout the investment casting process. Working closely with quality engineers and production personnel, this role performs receiving, in-process, and final receiving/shipping inspections, conducts metallographic and lab testing, verifies dimensional conformance using precision measuring tools, and maintains shop-floor compliance with AS9100D and Nadcap requirements.

Key Responsibilities: * Receiving, In-Process & Final Inspection: Perform visual, dimensional, and receiving inspections on raw materials (wax, slurry refractories, master heat alloys) and finished castings per customer drawings, PO requirements, and process travelers.* Laboratory & Metallurgical Support: Prepare metallographic samples (sectioning, mounting, polishing, etching) and perform hardness testing (Rockwell, Brinell), grain size analysis, and chemistry verification (OES/XRF spectrometry) under supervision.* Dimensional Inspection & Gage Control: Operate precision layout and measuring equipment—including height gages, micrometers, calipers, surface plates, optical comparators, and air gages. Perform routine calibration checks on shop-floor gages and measuring tools.* First Article & Documentation Support: Assist Quality Engineers in gathering dimensional and material test data for AS9102 First Article Inspection Reports (FAIR) and customer quality packages.* Non-Conformance & Traceability Handling: Identify, isolate, and tag non-conforming material. Issue internal non-conformance reports (NCRs) in the ERP system and ensure complete lot/heat traceability throughout post-cast operations.* Audit & Standard Compliance: Conduct internal process audits to verify operator compliance with standard work instructions, AS9100D guidelines, and Nadcap special process requirements.

Required Qualifications: *

Education: High School Diploma or GED required; Associate degree in Mechanical, Manufacturing, Quality, or Metallurgical Technology is preferred.*

Experience: 2+ years of hands-on quality technician or inspector experience in aerospace manufacturing, precision machining, or foundry environments.*

Technical Skills: * Strong ability to read and interpret complex aerospace engineering blueprints and shop travelers.* Basic knowledge of Geometric Dimensioning and Tolerancing (GD&T per ASME Y14.5).* Proficiency in using precision mechanical inspection tools and standard office software (Excel, ERP systems).* Vision & Physical Requirements: Annual vision screening required. Ability to lift up to 35–40 lbs safely. Ideal candidate would possess the following qualifications. However, these are not mandatory for consideration.* ASQ Certified Quality Technician (CQT) or Certified Mechanical Inspector (CMI).* Prior experience in a precision investment casting foundry (working with ferrous and non-ferrous alloys)* Experience assisting with CMM operational checks or portable inspection arms (FARO/Romer).* Knowledge of AS9100D and Nadcap quality system documentation.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
