Job Description

We are looking for an experienced CNC Machinist to join our team in Buena Park, California. This is a hands-on machining position supporting the production of precision components for the aerospace and defense industries.

  • Work with calipers, micrometers, gauges, and other inspection tools.
  • Identify and troubleshoot machining issues and make appropriate adjustments.
  • Follow established machining processes, quality procedures, and safety requirements.
  • Maintain accurate production and inspection records.
  • Work with supervisors, programmers, engineers, and quality personnel to resolve production issues.
  • Maintain a clean, organized, and safe work area.
  • Help identify opportunities to improve machining processes, quality, and efficiency.
  • Support the production of precision components used in aerospace and defense applications.


Requirements

  • Previous experience working as a CNC machinist in a manufacturing environment.
  • Ability to read and understand engineering drawings and GD&T.
  • Experience setting up and operating CNC machinery.
  • Ability to make tool offsets and basic program adjustments.
  • Proficiency using precision measuring instruments such as micrometers, calipers, and gauges.
  • Experience with aerospace, defense, medical, or other precision manufacturing is a plus.
  • Experience with CNC mills, lathes, or both is preferred.
  • Familiarity with Fanuc, Haas, Mazak, Okuma, or similar controls is a plus.
  • CNC programming experience is a plus but not required.
  • Experience with CAM software such as Mastercam is a plus but not required.
