CNC Programmer-Machinist

CNC Programmer / Machinist

A precision aerospace manufacturer is seeking an experienced CNC Programmer/Machinist to support precision machining operations in our aerospace manufacturing environment. This role develops, modifies, and optimizes CNC programs; supports machine setups and first-article production; troubleshoots machining issues; and ensures programs consistently produce parts that meet customer drawings, specifications, and quality requirements.

The ideal candidate has 6+ years of CNC programming and machining experience, strong proficiency in Mastercam and GibbsCAM, hands-on experience with Swiss CNC machines, and familiarity with JobBOSS or a similar ERP/job management system.

• CNC Programming, Setup & Machining
  • Create, modify, and optimize CNC programs (Mastercam, GibbsCAM) and toolpaths from customer drawings, models, and specs.
  • Program and support Swiss CNC machines, mills, lathes, and other multi-axis equipment.
  • Plan machining sequences, select tooling/work holding/cutting parameters, and set work/tool offsets.
  • Prove out new and revised programs (simulation, single-block operation, controlled first cycles) and support first-article inspection to verify parts meet requirements before release to production.
  • Perform in-process inspections using calipers, micrometers, indicators, and height gauges.
  • Diagnose and correct dimensional issues, surface finish problems, tool wear/breakage, chatter, work holding issues, and programming errors.
  • Optimize existing programs for cycle time, tool life, setup time, and repeatability.
• Production & Technical Support
  • Provide hands-on programming support to machinists and production staff; work with Production and Quality to resolve machining and manufacturing issues.
  • Review drawings and job requirements before releasing work; flag missing or unclear information before it affects production.
  • Support new job introduction, first articles, and process improvements; communicate production risks, delays, and tooling needs.
  • Own programming errors — contain affected work, correct the root cause, and help prevent recurrence.
• JobBOSS & Documentation
  • Use JobBOSS to manage job information, routings, and work orders.
  • Maintain organized program, setup, and tooling files with clear naming and revision control, ensuring programs match the correct part number/revision and obsolete files are never used in production.

• 6+ years of CNC programming and machining experience in precision manufacturing.
• Strong proficiency in Mastercam and/ ability to independently create machining strategies, not just run existing programs.
• Demonstrated experience programming and troubleshooting Swiss CNC machines, mills, lathes, or other multi-axis equipment.
• Solid understanding of G-code, tooling, work holding, offsets, feeds/speeds, and program prove-out.
• Ability to read complex engineering drawings, tolerances, and material/finish callouts; working knowledge of GD&T.
• Experience with first-article and in-process inspection using precision measuring tools.
• Experience with JobBOSS or a similar ERP/job management system.
• Strong attention to detail, mechanical aptitude, and communication skills; comfortable working cross‑functionally with Production, Quality, Planning, and Operations.

• Dental insurance
• Health insurance
• Life insurance
• Paid time off
