Heavy-Duty Trailer Systems Technician

A day in the life

In Saint Paul, MN, your morning starts with a safety check and a quick huddle with teammates. You review the service queue, pull the first trailer into the bay, and dive into diagnostics—maybe it's a brake imbalance, a wiring fault in the lighting harness, or a suspension component that needs attention. Midday brings a compliance inspection, accurate documentation of the work you completed, and a call-out to a teammate to collaborate on a tricky hydraulic issue. You wrap up by updating maintenance records, reviewing parts needs, and sharing ideas to improve the workflow for tomorrow.

• Execute scheduled service and corrective repairs on semi trailers—brakes, suspension, electrical, and related systems.
• Pinpoint mechanical issues using diagnostics and hands-on troubleshooting to restore peak performance.
• Conduct safety and compliance inspections, recommending repairs or part replacements when needed.
• Document all maintenance and repair activities with accuracy and clarity.
• Partner with fellow technicians to refine processes and elevate the quality of service.
• Keep current with industry trends and best practices in semi trailer care.
