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.

• 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.
