CNC Machinist

Key Responsibilities

• Program CAM (Fusion 360 / Mastercam) from engineering CAD models and own jobs end-to-end: setup, first article, and production of prototype parts.
• Design and build fixtures, soft jaws, and workholding to make repeat jobs fast.
• Set up and operate 3-axis CNC vertical mills, manual mill and lathe, and supporting shop equipment.
• Operate the sheet metal cell: waterjet cutting and CNC press brake forming, including nesting and bend programming.
• TIG weld brackets, enclosures, and fixtures as needed.
• Fabricate parts end-to-end: hardware insertion (PEM), deburring and surface finishing, and final fit-up of formed and welded assemblies.
• Manage the tool crib: track cutter and consumable inventory, buy tooling, and own vendor relationships for cutters, stock, and shop supplies.
• Inspect your own work using surface plate, height gauge, micrometers, and calipers to drawing GD&T.
• Support assembly and integration of prototype systems and racks when the schedule calls for it.
• Be flexible and help out around the shop: machine maintenance, material handling, rigging support, and keeping the floor safe and organized.
• Give design-for-manufacturability feedback directly to the engineers who sit a few steps away.
