Diesel Technician - Freightliner / Detroit Specialist

About Us / Job Overview

New Edge Diesels is an independent heavy-duty truck repair facility specializing in diagnostics, electrical troubleshooting, engine repair, aftertreatment systems, and fleet maintenance. We work primarily on Freightliner, Detroit Diesel, Cummins, Paccar, Volvo, Mack, and International trucks using OEM diagnostic software.
