About The Position

A&A Safety is seeking a skilled Diesel Mechanic for their 2nd shift operations. This role is for a technician who can independently diagnose and repair complex issues on a variety of heavy-duty diesel trucks and specialty equipment, rather than just replacing parts. The position involves working on approximately 350 trucks and trailers and 800 pieces of rolling stock across multiple branches. The ideal candidate is a problem-solver who can handle driveability, performance, and derate faults, as well as aftertreatment systems, high-pressure common rail fuel systems, and electrical/network diagnostics. The role also includes in-frame overhauls, hydraulic system repairs, and brake/suspension work. This is a rebuilding phase for the second shift, offering an opportunity to help shape the team.

Requirements

Substantial experience diagnosing and repairing medium- and heavy-duty diesel trucks and equipment across multiple engine platforms.
Ability to diagnose independently and build your own test plan.
Real aftertreatment and high-pressure common rail experience, not just resetting codes.

Valid driver's license and insurable driving record.
Willingness to work second shift and take part in the on-call rotation.
Ability to pass a drug screen, background check, and MVR review.
Must be able to lift up to 50 pounds regularly and up to 75 pounds occasionally or with assistance.
Must be able to perform extended standing, bending, kneeling, crouching, crawling, and overhead reaching.
Must have manual dexterity and vision adequate for close inspection and distinguishing wire colors.
