POSITION SUMMARY
The CNC Machinist owns the full machining process from setup and tooling selection through program editing, first article validation, and production. This role works on complex, tight-tolerance components across aluminum, steel, titanium, and specialty alloys for aerospace, defense, and energy applications. The environment includes multi-axis milling, turning, and mill-turn equipment, requiring strong problem-solving and technical skill. This is a high-accountability role with the opportunity to take on challenging work and make a direct impact on quality and performance.
KEY RESPONSIBILITIES
- Set up CNC milling centers, lathes, and multi-axis/mill-turn machines from print to first-part approval
- Select and qualify tooling, workholding, and fixturing appropriate to part geometry and material requirements
- Edit and optimize CNC programs at the control (G-code, conversational, or CAM post) to achieve required tolerances and surface finishes
- Perform first article inspection using CMM, precision hand tools, and surface measurement equipment; document results
- Run production lots, monitor in-process quality, and make offset and tooling adjustments to maintain process capability
- Interpret complex engineering drawings, GD&T callouts, and customer-specific requirements
- Support automation and lights-out machining cells, including robot-assisted operations
- Troubleshoot machining issues including chatter, tool breakage, dimensional drift, and surface finish defects
- Mentor CNC Operators and contribute to process improvement and cycle time reduction efforts
- Maintain accurate production records, traveler documentation, and tool inventory
REQUIRED QUALIFICATIONS
- 5+ years of CNC machining experience with demonstrated setup and program editing capability
- Proficiency on multi-axis CNC platforms (milling, turning, or combined mill-turn)
- Strong ability to read and interpret complex engineering drawings and GD&T (ASME Y14.5)
- Hands-on experience with precision metrology: CMM, surface plates, micrometers, bore gauges, and thread gauges
- Solid understanding of cutting tools, toolpath strategies, speeds and feeds, and workholding for various materials
- Experience machining aluminum, steel, stainless, and at least one specialty alloy (titanium, Inconel, etc.)
- Ability to work independently and manage priorities across multiple jobs simultaneously
- Commitment to first-time quality and zero-defect production
PREFERRED QUALIFICATIONS
- Experience on 5-axis milling centers (Mazak, DMG Mori, Haas, or similar)
- Mill-turn or Swiss-turn programming/operation experience
- Background in aerospace (AS9100) or defense manufacturing environments
- CAM programming experience (Mastercam, Fusion 360, Hypermill, etc.)
- Familiarity with CMM programming (Calypso, PC-DMIS, or equivalent)
- Experience supporting or working within lights-out/robotic automation cells
