  • 2nd Shift: 2:30 PM – 10:30 PM (+$2.00/hr differential)

The Role (Read This First — It Matters)

This is not a production machining role.

You’ll be working alongside Engineering to build and maintain tooling, fixtures, and quality-check fixture
s used throughout an in-house manufacturing operation. If your background is strictly pushing the green button on high-volume production parts, this won’t be the right fit. If you like solving problems, setting machines up correctly, and making tooling that other machinists rely on—welcome home.

What You’ll
  • Do Set up, maintain, and troubleshoot multiple CNC machines
  • Work from engineering drawings, setup instructions, and tool lists
  • Build, install, and remove fixtures, vises, and tooling accurately and safely
  • Perform routine tooling setup and maintenance (drills, end mills, taps, reamers, etc.)
  • Calibrate probes, tool setters, and other CNC setup equipment
  • Adjust tool offsets, work offsets, and part rotation as needed
  • Perform basic CNC program troubleshooting
  • Prepare material using shop equipment (band saw, surface grinder, etc.)
  • Maintain CNC machines (coolant, cleaning, filters, general upkeep)
  • Machine precision tooling and fixtures accurately and on schedule
  • Operate all equipment safely and professionally
What We’re Looking For
  • Associate degree in Machining OR 4–5+ years of hands‑on machining experience
  • Strong understanding of engineering drawings and shop math
  • Experience with CNC setup, not just operation
  • Owns and knows how to use basic machinist tools:
    Calipers, Micrometers, Test indicators
  • Mechanical aptitude and solid troubleshooting skills
  • Willingness to obtain forklift and hoist certification (employer‑provided training)
  • Union position
  • Degree or experience welcomed
  • Stable, long‑term opportunity with technical depth

If you like being the person Engineering trusts and production depends on, this role has your name all over it.
