Hypothetical example for Backroad Diesel Repair, a four-bay truck repair shop.
Backroad Diesel Repair is hiring a Diesel Mechanic for fleet and owner-operator trucks (Monday to Friday, 7 a.m. to 4 p.m., with a rotating Saturday). You'll diagnose, repair and document each job. Bring your hand tools; we provide the lifts and diagnostic equipment.

Common questions
Do I need a CDL for my diesel mechanics?
Not always. The Bureau of Labor Statistics says they might need one to test-drive large vehicles. If your shop road-tests trucks, require it; if not, say it is not needed.

Yes. Copy it, edit it and post it. It's a starting point written for any business, so fill in the brackets and adjust the duties to your actual job. If you'd rather have it written for your business, ready to post, our Job Description service is $30.
