Diesel Powertrain Diagnostic Technician

A day in the life — Newport News, VA

You roll into our Newport News, VA facility, grab the work orders for the day, and start with a quick safety check and setup of your bay. With diagnostic tools in hand, you dive into diesel powertrains—pinpointing faults in fuel delivery, chasing down electrical gremlins, and correcting exhaust issues that impact performance. Between jobs, you document what you found and what you fixed, keeping repair notes, maintenance logs, and parts usage tidy and accurate.

You’ll move from routine service on diesel-powered vehicles and equipment to deeper teardown-and-repair work, collaborating with teammates to keep projects on schedule. Throughout the day, you maintain a clean, orderly workspace and stick to safety protocols. And because you’re serious about the craft, you keep an eye on emerging diesel technologies and industry trends, bringing fresh insights back to the team.
