  • 10+ years in a manufacturing environment with strong exposure to CNC machining.
  • Proficiency in G-code programming (AP100 or similar).
  • Experience with SolidWorks for prints, models, and manufacturability.
  • Strong understanding of Lean manufacturing, process flow, and continuous improvement.
  • Proven ability to lead floor-level engineering support and manage multiple priorities.
  • Excellent communication, organization, and presentation skills.
  • Ability to work both independently and in cross-functional teams
Preferred Skills
  • Experience with CNC machine setup, tooling selection, and fixture design.
  • Knowledge of sheet metal fabrication, laser cutting, or punching preferred.
  • Familiarity with GD&T and print interpretation.
  • Background with automation, robotics, or Industry 4.0 initiatives.
  • Experience optimizing cycle times, feeds/speeds, and tool life.
  • Ability to analyze machining data and leverage metrics for decision-making.
  • Knowledge of ERP/MRP systems for routing, BOMs, and work orders.
  • Experience leading capital equipment upgrades or process technology improvements.
  • Exposure to AP100, SigmaNEST, Mastercam, or similar CAM software.
