CNC Machinist - Level I, II, & III

We are exploding with new and returning work — and we’re looking to add CNC Machinists at all experience levels to support continued growth. Located in Bay City, Michigan, we machine large, precision components for aerospace, defense, energy, and industrial customers.

This is a large-format machining environment, not repetitive small-part production. We offer a stable workload, strong programming support, and opportunities to grow your skills as demand continues to increase.

Whether you’re early in your CNC career or a seasoned Level III machinist who thrives on complex setups and problem-solving, we want to talk to you.

Shift Schedule: 2nd Shift; 4:15pm - 2:45am, Monday - Friday.
