- Preventative maintenance services
- DOT inspections
- Swing and roll-up door repairs
- Light welding (preferred)
- Maintain accurate daily work orders
- Keep service truck clean and organized
- Follow all customer safety procedures
You will represent the company at customer job sites — professionalism matters.
What We’re Looking For
- Minimum 8 years of tractor & trailer repair experience
- Strong diagnostic ability (not just parts replacement)
- Proficient in Cummins & Detroit diagnostic software (Required)
- Volvo & Mack experience (Preferred)
- Experience with Class 6, 7 & 8 trucks (Required)
