Northrop Grumman s Space Sector invites you to bring your pioneering spirit to our collaborative teams. As a CNC Programmer 3 located in Commerce, CA, you ll be a linchpin in missions of paramount importance, defining the art of the possible from day one.

Our Commerce, CA site is in search of CNC Programmer 3 to join our growing team on a 9/80 schedule.

The CNC Programmer 3 is a specialized professional responsible for converting complex 3D engineering designs into precise numerical code (G-code/M-code) that drives multi-axis machining centers using CAD/CAM software. In the aerospace industry, this role requires working with exotic materials (titanium, Inconel, aluminum alloys) and maintaining extremely tight tolerances, often within ±0.001".

• Program Development:
  Utilize software such as Mastercam, CATIA, or Siemens NX to create toolpaths for 3-, 4-, and 5-axis milling and mill-turn machines. Designing complete NC programs for complex 3, 4, and 5-axis mills, lathes, and mill-turns using CATIA V5/V6.
• CAD/CAM Integration:
  Analyze 3D CAD models and blueprints to determine the most efficient machining sequences and work-holding strategies.
• Tooling & Fixture Design:
  Design custom fixtures and jigs in CAD to secure aerospace components during the machining process.
• Simulation & Verification:
  Conducting machine simulations (e.g., using Veri cut or Completed) to ensure error-free toolpaths before physical production.
• Process Optimization:
  Continuously refine programs to reduce cycle times, improve tool life, and ensure consistent quality for high-value aerospace parts like landing gear or turbine blades. Researching tools and methods to reduce cycle times, improve part quality, and ensure cost-effective manufacturing.
• Documentation:
  Create detailed setup sheets and tool lists to guide machinists through the production process.
• Shop Floor Support:
  Troubleshooting programming issues during setup, performing "prove-outs" on the floor, and mentoring machine operators.

• Education:
  
  High school diploma/GED and 4+ years of experience developing CNC programs for multi-axis machines in an aerospace environment
• Software Proficiency:
  Deep knowledge of CAD software (e.g., AutoCAD, Solid Works) and CAM software (e.g., Mastercam, Gibbs CAM).
• Blueprints & GD&T:
  Expert ability to interpret complex technical drawings and Geometric Dimensioning and Tolerancing (GD&T) symbols.
• Mathematical Aptitude:
  Strong foundation in Trigonometry and Geometry for calculating complex cutting paths and angles.
• Technical Knowledge:
  Deep understanding of G-code, M-code, and post-processing; expertise in machining aerospace alloys (Titanium, Inconel, Aluminum).

• Regulatory Compliance:
  Familiarity with AS9100 standards and export control regulations (ITAR/EAR).
