The Mill Machinist III is a senior-level machinist responsible for complex CNC and/or manual milling setups, advanced troubleshooting, and manufacturing high-precision aerospace components. This position operates with minimal supervision and serves as a technical resource and mentor to junior machinists while ensuring compliance with aerospace quality and regulatory standards.
Essential Duties and Responsibilities:
Independently set up, operate, and optimize complex CNC and/or multi-axis milling machines.
Interpret complex engineering drawings, blueprints, and GD&T requirements.
Develop setup strategies, select tooling, and design/modify fixtures as needed.
Perform first article inspections (FAI), in-process, and final inspections in accordance with AS9100 and customer specifications.
Hold tight tolerances (±.0002”–±.0005” typical in aerospace applications).
Troubleshoot advanced machining, tooling, and process issues to improve efficiency and reduce scrap.
Make program edits at the machine (G-code) and recommend process improvements.
Collaborate with Manufacturing Engineering on process development and continuous improvement initiatives.
Train and mentor Mill Machinist I and II team members.
Ensure compliance with safety standards, quality systems, and regulatory requirements (e.g., ITAR if applicable).
Maintain accurate production, inspection, and traceability documentation.
Requirements
Advanced knowledge of CNC controls (e.g., Fanuc, Haas, Mazak).
Strong proficiency in GD&T and complex blueprint interpretation.
Experience with multi-axis machining (4-axis/5-axis preferred).
Demonstrated ability to troubleshoot and optimize machining processes.
High level of proficiency with precision measurement tools and inspection techniques.
Education/Experience:
High school diploma or GED required; technical degree or apprenticeship preferred.
5–8+ years of milling experience in a precision manufacturing environment; aerospace experience strongly preferred
