About the Job

Requirements

  • At least 5 years of CNC programming experience, including hands-on programming of 5-axis milling and Swiss-type lathes with live tooling.
  • Proficiency with a major CAM package, such as Mastercam, Esprit, GibbsCAM, or Fusion 360, including multi-axis and mill-turn modules.
  • Working knowledge of G-code and M-code, control platforms such as Fanuc, Siemens, Citizen, Star, and Tsugami Swiss controls, and post-processor behavior.
  • Ability to read and interpret complex engineering drawings and apply geometric dimensioning and tolerancing (GD&T).
  • 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.
  • Ability to stand, lift, and carry equipment up to 50 pounds unassisted.
  • Ability to work all required shift hours, overtime, and/or weekends as needed.

Responsibilities

  • Develop, prove out, and optimize CNC programs for 5-axis machining centers, CNC lathes, and Swiss-type lathes with live or driven tooling and sub-spindle operations.
  • Translate engineering models and drawings into manufacturing processes by selecting tooling, work-holding and fixturing, cutting strategies, and machining sequences.
  • Generate and maintain CAM programs, post-processors, tool libraries, and setup sheets; verify programs through simulation and verification before floor release.
  • Lead first-article runs and process prove-out; drive cycle-time reduction, tool-life improvement, and scrap reduction without compromising tolerance or surface finish.
  • Author and maintain process documentation, including setup sheets, work instructions, and tooling lists, to support traceability and repeatability.
  • Partner with Manufacturing and Quality Engineering on tolerance feasibility, inspection planning, and first-article inspection (FAI/AS9102) requirements.
  • Support equipment commissioning and capability studies as new machine tools are installed during facility ramp-up.
  • Mentor machinists and operators on setup, in-process adjustment, and program intent.
  • Identify and recommend tooling, software, and process improvements to support the transition from prototype to rate production.

Desired Qualifications

  • Experience in a regulated manufacturing environment such as NQA-1, AS9100, or ISO 9001, preferably in 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 coordinate measuring machine (CMM) and inspection processes and first-article inspection (FAI).
  • Exposure to manufacturing execution system (MES)/enterprise resource planning (ERP)-driven shop-floor systems and digital process documentation.
  • Lean manufacturing or continuous-improvement experience, including cycle-time reduction, single-minute exchange of die (SMED), or scrap reduction.
  • Journeyman machinist background or a formal machining/CNC technical credential.
