Production Manager / Lead Machinist

Every precision part that leaves our shop has to be perfect — and you're the one who makes sure it looks and feels that way. As a Deburring & Finishing Technician, you'll hand-finish CNC machined parts to customer specifications, removing burrs, sharp edges, and surface imperfections. You'll work with deburring tools, tumbling media, bead blast equipment, and prep parts for anodize, plating, and other surface treatments.

This is an excellent entry point into precision manufacturing. You'll learn how parts are made, what aerospace quality standards look like, and how to handle high-value components. Many of our machinists started in finishing. We're a startup — if you show up, work hard, and pay attention, there's a real path to a machining career.
