Northrop Grumman Mission Systems (NGMS) is looking for you to join our Marine Systems team as a highly motivated & skilled Principal or Senior Principal CNC Programmer based out of Sunnyvale, CA. Marine Systems is a leading provider of naval propulsion and tactical equipment support systems. This position requires a candidate who will specialize in the fabrication (machining) of high value large-scale precision metal components (low-volume / high-mix) and someone with a strong background and working knowledge of metal removal/machining fundamentals and computer numerical control (CNC) programming experience.

What You'll get to Do:

  • Create and edit CNC programs that support the machining of large-scale, complex, precision metal components fabricated on multiple-axis CNC milling & turning machining centers (CAM file generation, post-processor machine code generation).

  • Perform technical data package review of components that require fabrication (CAD model & engineering drawing validation).

  • Perform machining process development & optimization (part setup/fixturing, machining strategy/order of operations, tool selection, speed/feed process parameter selection).

  • Identify, select, and procure appropriate tooling for job specific applications (based on part material, geometry, features, tolerances, system rigidity, and equipment capability).

  • Perform program prove-out validation (computer simulation tools, 'table top' peer reviews, First Time Process Reviews, machine dry runs).

  • Work with machinists, manufacturing engineers, and design engineers to identify process improvement opportunities (reduced machining/setup time, improved part quality, reduced manufacturing risk) and incorporate required design changes (customer driven changes, technical performance improvements, improved manufacturability).

  • Participate in and lead cross-functional teams comprised of machinists/operators, manufacturing engineers, production supervisors, supply chain representatives, quality engineers/inspectors, and operations/program management to support program schedule & performance goals, mitigate manufacturing risks, and improve operational efficiency.

  • This position is for a 1st Shift position; however, occasional extended shift, off-shift, and/or weekend support maybe required.

  • Occasional travel may be required for training purposes or to participate in equipment selection/acceptance activities (less than 10%).
