About the Role
We are seeking a senior-levelCNC Machinist III to join our precision manufacturing team. In this role, you will be responsible for the setup, programming edits, and operation of multi-axis CNC machine tools (mills, lathes, grinders) to manufacture complex, tight-tolerance metal components from blueprints and CAD/CAM models.
This position collaborates closely with manufacturing engineering and CAM programming to develop custom fixturing, optimize cut paths, and drive production efficiency.
Key Responsibilities
- Setup & Operation: Complete complex machine setups independently, rapidly, and accurately; run high-mix production runs to exact specifications.
- Programming & G/M Code: Read, interpret, and edit G&M code directly at the machine controller; partner with CAM programming to refine and troubleshoot CNC tool paths.
- Tooling & Fixturing: Design, build, and adapt holding fixtures and custom tooling for complex part geometries.
- Quality & In-Process Inspection: Inspect first-article and in-process parts using precision metrology tools (micrometers, calipers, height gauges, bore gauges) following Quality Management System (QMS) guidelines.
- Process Optimization: Advise supervisory and programming teams on tooling, feeds/speeds, and cycle-time enhancements.
- Shop Coordination: Track jobs, log machine performance data, and maintain preventive maintenance standards across assigned machine tools.
Qualifications & Requirements
- Experience: 8+ years of hands-on CNC machine setup and operation (mills, lathes, or grinders).
- Programming Fluency: Strong proficiency in G&M code editing and machine-level parameter adjustments.
- Print Reading: Advanced ability to interpret complex engineering blueprints, drawings, and GD&T symbols.
- Education: High school diploma or GED required; post-secondary vocational degree or CNC certification preferred.
- Metrology: Proven experience using standard precision measurement inspection tools to hold tight tolerances.
- Environment: Ability to stand for full shifts and work in an active machine shop environment with moderate noise and airborne metal particulate exposure.
