We pride ourselves on honest work, quality repairs, and getting our customers’ trucks back on the road.

Position Overview

We are seeking an experienced Heavy-Duty Diesel Mechanic with hands-on Cummins engine experience to join our team.

We are specifically looking for someone familiar with Cummins ISX, X15, and similar heavy-duty Cummins platforms who is comfortable performing engine-related repairs as well as general heavy-duty truck work.

The ideal candidate will also have experience with brakes, clutches, transmissions, engine swaps, diagnostics, and major mechanical repairs.

Steady, year-round work

Established family-owned repair shop

PLEASE NOTE

We are specifically hiring for Cummins engine experience. If your background is primarily automotive, equipment, aviation, or general mechanical work without hands-on heavy-duty Cummins engine experience, this position may not be the right fit. However, if you have experience with other heavy duty engines but can do jobs like clutches, transmissions, engine swaps, turbos, manifolds, brakes - still apply!
