Heavy‑Duty Semi‑Trailer Service Technician — St. Paul, MNOur mission

We keep trailers safe, compliant, and on the road—because reliable equipment powers every successful haul. If you care about precision, safety, and teamwork, you’ll fit right in.

Imagine the challenge

A trailer arrives with uneven brake wear, a tired suspension, and an intermittent light issue. You assess, diagnose, and plan the repair. Systems checked, components replaced or adjusted, electrical gremlin found and fixed. You update the service record, confer with a teammate to fast‑track the next unit, and reset the bay—clean, organized, and ready.

Responsibilities you’ll own
  • Perform preventive maintenance and repairs on semi trailers, covering brake, suspension, and electrical systems.
  • Diagnose mechanical problems and troubleshoot effectively to resolution.
  • Inspect trailers to ensure safety compliance and adherence to industry standards.
  • Maintain clear, accurate documentation of all maintenance and repairs.
  • Collaborate with colleagues to meet project timelines and shop goals.
  • Uphold a tidy, safe work environment in alignment with safety protocols.
  • Keep pace with industry developments and new trailer technologies.
Bring these qualifications
  • High school diploma or equivalent; mechanical trade training is beneficial.
  • Proven mechanic background—ideally with semi trailers or heavy‑duty vehicles.
  • Strong knowledge of mechanical systems and diagnostic tools.
  • Ability to work both independently and within a team.
  • Excellent problem‑solving and attention to detail.
  • Valid driver’s license with a clean record.
  • Flexibility for variable hours, including overtime as required.
