About the Job

Requirements

  • A high school diploma or General Education Diploma (GED) and six years of experience as a CNC programmer or machinist are required.
  • Proficiency in programming using Mastercam, Smartcam, or GIBBS is required.
  • Experience with Swiss-type turning, such as Tsugami, and/or mill-turn operations is required.
  • Experience in multi-axis machining and turning with live tooling is required.
  • Experience in high-speed machining is required.
  • Ability to read and interpret engineering drawings and geometric dimensioning and tolerancing (GD&T) is required.
  • Proficiency with precision measuring tools and basic inspection documentation is required.
  • Working knowledge of feeds and speeds, tool selection, and work holding for common aerospace materials such as aluminum, titanium, and stainless steels is required.
  • Experience working from travelers or operation sheets and controlled process documentation in an AS9100-compliant or similar environment is required.
  • Ability to work second shift, from 3:30 PM to 12 AM, is required.

Responsibilities

  • Independently set up and operate CNC and manual equipment to produce complex aerospace hardware in accordance with company procedures.
  • Machine a range of materials, interpret engineering drawings and models with GD&T, and plan and execute turning and mill-turn operations from setup through final inspection.
  • Select turning tooling and work holding, set and verify work and tool offsets, create, adjust, and optimize CNC programs at the machine, and resolve common machining issues to protect quality, schedule, and cost.
  • Use precision measurement tools to validate product conformance, follow workmanship, foreign object debris (FOD) control, handling, and special process requirements, and maintain a clean, safe, audit-ready work area.
  • Mentor junior machinists and apprentices.
  • Collaborate with Manufacturing Engineering, Quality, Planning, and Production to improve manufacturability.
  • Support continuous improvement, including 5S and lean practices, and use CAM tools such as Mastercam (2020 or higher), Vericut, Catia, and NX to improve process robustness and repeatability.

Desired Qualifications

  • Experience machining space or aerospace hardware, preferably for Northrop Grumman Space or similar organizations.
  • Familiarity with Northrop Grumman Space or equivalent machining-related procedures, special process specifications, and workmanship standards.
  • Ability to set up and operate CNC milling machines or multi-axis machining centers for complex, tight-tolerance features and prismatic work.
  • Experience with common CNC controls such as Fanuc, Haas, Siemens, or Mazak, including basic program edits and troubleshooting.
  • Experience with Vericut, NX, Catia5, and AutoCAD.
  • Participation in material review board (MRB), corrective actions, or lean and continuous improvement activities.
  • Experience training or assisting less experienced machinists on setups and best practices.
  • Ability to guide apprentices in the Apprentice Program as a mentor.
  • Ability to obtain and maintain required company and/or government clearances.
  • Ability to set up and operate CNC milling machines for moderately complex, tight-tolerance parts with limited supervision.
  • A conventional machining background.

About the Company

Northrop Grumman

Builds stealth bombers, missiles, and satellites

Northrop Grumman builds military aircraft, missiles, rocket motors, satellites, and electronic systems, mostly for the American military and allied governments. It designed the B-2 stealth bomber and built NASA's James Webb Space Telescope, the largest telescope ever sent to space. The company works through four businesses: aircraft, missiles and ammunition, radar and communications systems, and space hardware such as satellites and solid rocket boosters. Most revenue comes from long-term government contracts, many of them classified. Its roots go back to Northrop Aircraft, founded in 1939, and it took its name after buying Grumman in 1994 and is based in Falls Church, Virginia.
