• Sustain a preventive maintenance program for every mold, with a repair history for each tool
• Act on work orders from the Manufacturing and Engineering teams, confirm the root cause, and support mold qualification after repairs

• Keep the tool room safe, organized and clean

  • Working knowledge of SolidWorks or a similar CAD system
  • CNC programming (CAM)
  • Experience in a small shop handling everything from repairs to vendor management
