Heavy-Duty Diesel Service Technician

What a day looks like in San Diego, CA

You roll into our supportive shop, grab a fresh work order, and begin with a safety walk-around. A hauler arrives with a loss-of-power complaint—you connect diagnostic tools, interpret data, trace an electrical fault, and bring the engine back to full strength. Between jobs, you log precise notes, collaborate with teammates on process tweaks, and keep your bay spotless. Before the day ends, you button up a scheduled service on a lift truck, road-test for performance and safety, and close out the repair order with crystal‑clear documentation.
