What you will do
- Develop, prove out, and optimize CNC programs for 5-axis machining centers, CNC lathes, and Swiss-type lathes.
- Translate engineering models and drawings into manufacturing processes.
- Generate and maintain CAM programs, post-processors, tool libraries, and setup sheets.
- Lead first-article runs and process prove-out.
- Author and maintain process documentation.
- Partner with Manufacturing and Quality Engineering on tolerance feasibility and inspection planning.
- Support equipment commissioning and capability studies.
- Mentor machinists and operators on setup and program intent.
- Identify and recommend tooling, software, and process improvements.
Required qualifications
- 5+ years of CNC programming experience, including 5-axis milling and Swiss-type lathes with live tooling.
- Proficiency with a major CAM package — Mastercam, Esprit, GibbsCAM, or Fusion 360.
- Strong working knowledge of G-code/M-code, control platforms, and post-processor behavior.
- Ability to read and interpret complex engineering drawings and apply GD&T.
- Demonstrated experience machining precision components in metals such as stainless steels, titanium, aluminum, and/or high-temperature/superalloys.
- Practical knowledge of work-holding, fixturing, tooling selection, and feeds/speeds optimization.
- Comfort working in a documented quality environment with full part traceability.
- Physical effort including standing, lifting, and carrying equipment up to 50 lbs. unassisted.
- Must be able to work all required shift hours, overtime and/or weekends as needed
Nice to have
- Experience in a regulated manufacturing environment — NQA-1, AS9100, or ISO 9001 — preferably nuclear, aerospace, or defense.
- Experience supporting prototype-to-production transitions or new-facility/equipment commissioning.
- Familiarity with mill-turn machining and macro/parametric (custom macro) programming.
- Working knowledge of CMM/inspection processes and first-article inspection (FAI).
- Exposure to MES/ERP-driven shop-floor systems and digital process documentation.
- Lean manufacturing or continuous-improvement experience.
- Journeyman machinist background or formal machining/CNC technical credential.
