We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they’re making history.

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 isa 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”.

Core Responsibilities

• 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.

Basic Qualifications

• Education: High school diploma/GED and 4+ years of experience developing CNC programs for multi-axis machines in an aerospace environment
