Job Description

Step Into the Heart of Zūm Fleet Care

Picture your day: you kick off with a quick review of driver notes, hook up diagnostic tools, and track down root causes across complex diesel systems. By midday you’ve completed a preventive maintenance inspection and a road test to validate a fix. Later, you program a telematics device, document parts and labor on your tablet, and head out for an on-the-road repair—always with safety and compliance front of mind.

• Pinpoint faults and repair systems including steering and steering systems, electrical, cooling, lubrication, braking, drivetrains, suspensions, clutches, transmissions, and oil/temperature/gas regulating components.
• Adjust, test, and rebuild engines and perform related tasks aligned with Federal, State/Provincial, and local requirements.
• Conduct test drives during preventive maintenance to investigate driver-reported concerns, and perform post-service test drives to confirm repairs.
• Install, program, replace, and verify telematics units.

• Execute preventive maintenance programs for all vehicles assigned to the facility.
• Tackle unscheduled repairs as they arise to minimize downtime.

You enjoy tracing symptoms to root causes across mechanical and electrical systems—whether that’s rebuilding an engine, diagnosing intricate wiring issues, or executing a meticulous PM. Your workspace is organized, your tools are cared for, and your documentation is complete. Above all, you take ownership and aim for first-time fixes.

• At least five years of Auto/Truck or Bus mechanical repair experience.
