CNC Programmer II

The Senior CNC Machine Programmer supports aerospace production operations by developing, optimizing, and maintaining CNC programs using Mastercam and/or Siemens NX. This position ensures precision machining of complex aerospace components to meet stringent quality, tolerance, and process control requirements. The ideal candidate combines deep CNC programming expertise with hands-on problem-solving skills and a strong understanding of aerospace materials and manufacturing standards.

Key Responsibilities:
• Program and optimize 3-, 4-, and 5-axis machining operations for aerospace components using Mastercam and/or Siemens NX.
• Support production teams by troubleshooting machining issues, validating tool paths, and implementing program updates that enhance quality, tool life, and efficiency.
• Interpret complex aerospace drawings, 3D CAD data, and GD&T specifications in accordance with ASME Y14.5 and AS9100 quality standards.
• Develop tool paths tailored for aerospace-grade materials such as titanium, Inconel, stainless steels, and aluminum alloys.
• Collaborate closely with machinists, setup personnel, and manufacturing engineers to ensure consistent production performance and minimize downtime.
• Conduct post-processing, toolpath simulation, and verification to ensure collision-free, production-ready programs.
• Maintain organized program files, setup instructions, and tool lists for repeat or legacy part production.
• Assist in tooling and fixture design reviews, recommending process improvements that reduce cycle times and ensure repeatable accuracy.
Serve as a programming technical resource, mentoring peers and operators on machining techniques and best practices.
