Heavy Equipment Diesel Systems Technician

Own the uptime in our Deer Park truck shop Picture this: you arrive at Clean Harbors Deer Park, gear up, and kick off a 12-hour shift in a shop that lives and breathes safety. You open your work orders, run diagnostics with computer instrumentation, and dive into troubleshooting—hydraulic leaks, stubborn valves, a Caterpillar engine that needs attention, or an A/C system service.

After repairs, you test every system against manufacturer specs, button things up, and get critical mobile equipment back to work. That’s a day in the life of our Facility Maintenance Repair I (Truck Shop Equipment Mechanic)—the diesel expert who keeps operations moving.
