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 skills. 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
