Job Description

Mobile Truck and Trailer Mechanic

Position Overview:

We’re adding a dependable, self-directed mechanic to service heavy-duty trucks and trailers where they sit: customer yards, job sites, and the roadside. You’ll keep fleet units safe, compliant, and moving, working mostly on your own and putting the customer first.

What You’ll Do:

• Answer roadside calls and emergency breakdowns quickly, getting equipment back into service.
• Troubleshoot and repair mechanical, electrical, and hydraulic problems on trucks and trailers, using scan tools and diagnostic software to pinpoint engine and system faults.
• Handle preventive maintenance, including oil changes, brake inspections, and tire service.
• Keep units compliant with DOT rules and company safety standards.
• Document your work and close out work orders accurately in the company system.
• Keep dispatch, drivers, and management updated on repair status and recommendations.

Schedule and Travel:

• Typically Monday through Friday, 7 AM to 5 PM, with flexibility as business needs change.
• Local and regional driving to either customer, or roadside, locations.

Qualifications:

• High school diploma or equivalent; diesel technology certification is a plus.
• 2–3+ years of heavy-duty truck and trailer repair experience.
• Solid working knowledge of diesel engines, air brake systems, electrical systems, and hydraulics.
• Comfortable using diagnostic equipment and reading schematics.
• Valid driver’s license with an acceptable driving record. CDL and ASE certifications are preferred, not required.
• Organized and able to manage your own time.
• Comfortable working outdoors in all weather conditions.

Ideal Candidate Experience:

• Experience servicing Class 7 and Class 8 commercial trucks.
• Experience with roadside breakdowns, mobile service, or field repairs.
• Ability to diagnose problems independently rather than simply replacing parts.
• Experience using electronic diagnostic software and scan tools.
• Familiarity with DOT inspections, preventive maintenance, and fleet safety requirements.
• Experience repairing trailers, including brakes, suspension, lighting, landing gear, and wheel-end components.
• Strong communication skills when dealing with drivers, dispatchers, and customers.
