About The Position

DuraFleet is looking for an experienced Lead Mobile Diesel Technician to provide maintenance and repair services for commercial fleet customers throughout the Charleston metro. This is an opportunity to help build a new territory backed by an established and expanding mobile fleet service brand. The ideal candidate is a skilled, dependable technician who can diagnose problems accurately, complete quality repairs in the field, communicate professionally with customers, and document work thoroughly. Charleston's industrial base - the Port, the I-26 corridor, the manufacturing and distribution operations stacked along I-526 - runs on diesel equipment that can't afford downtime. DuraFleet exists to fix that: fast, honest, professional mobile service that keeps fleets moving. We're building a reputation on fairness and 5-star service, not on flat-rate games or upsells. The person we hire for this role sets that tone from day one.
