• Experience with CAD software (Siemens NX, AutoCAD, SolidWorks) and CAM software (Mastercam, Gibbs CAM).
• Expert interpretation of complex technical drawings and GD&T symbols.
• Solid foundation in trigonometry and geometry for calculating cutting paths and angles.
• Understanding of G-code, M-code, and post-processing; expertise in machining aerospace composites and alloys (Titanium, Inconel, Aluminum).
• Ability to obtain and maintain U.S. Government clearance and Special Program Access (PAR).

Responsibilities

• Develop precise NC programs using Mastercam, CATIA, or Siemens NX for 3-, 4-, and 5-axis milling and mill-turn machines.
• Integrate 3D CAD models and blueprints to design efficient machining sequences and work-holding strategies.
• Design custom fixtures and jigs in CAD for mandatory aerospace component support.
• Conduct machine simulations (e.g., VeriCut) to verify error-free toolpaths before production.
• Continuously optimize programs to reduce cycle times, improve tool life, and maintain high quality on high-value aerospace parts.
• Create detailed setup sheets and tool lists to guide machinists through the production process.
• Provide shop floor support, troubleshoot programming issues during setup, perform prove-outs, and mentor machine operators.
