Dura Fleet 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. Dura Fleet 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.

Hands-on technical work:

• Perform preventive maintenance, inspections, diagnostics, and repairs on commercial fleet vehicles
• Diagnose diesel engine, electrical, brake, steering, suspension, drivetrain, and related system concerns
• Use diagnostic equipment, multimeters, service information, and sound troubleshooting practices across light-, medium-, and heavy-duty equipment
• Complete mobile repairs at customer facilities, fleet yards, and roadside locations throughout the Charleston metro
• Conduct thorough vehicle inspections and flag safety or maintenance concerns before they become breakdowns
• Maintain accurate digital work orders - labor, parts, notes, inspections, and photos
• Keep your service vehicle, tools, and equipment organized and road-ready

As the Charleston operation grows:

• Help establish strong service standards for future Dura Fleet Charleston technicians
• May participate in interviewing and evaluating candidates as Dura Fleet hires additional technicians
• May mentor and train other technicians on diagnostics, repair quality, and customer communication
• Coordinate with the Business Owner on parts, approvals, pricing conversations, and job planning
• Represent Dura Fleet professionally with fleet customers - clear communication, honest recommendations, no surprises
• Deliver excellent customer service on every call, every time - this is how Dura Fleet builds its reputation

• At least three years of commercial vehicle, diesel, fleet, or heavy-equipment maintenance experience
• Strong independent diagnostic and mechanical troubleshooting ability - comfortable being the only technician on site
• Experience with preventive maintenance, electrical systems, brakes, steering, and suspension across a range of equipment, from light-duty up to heavy-duty
• Confidence with electronic diagnostic tools and OEM/aftermarket service software
• Ability to complete accurate digital documentation using cloud-based service systems
• Professional communication and customer service skills - you're often the only Dura Fleet representative a customer sees
• Valid driver's license and a driving record acceptable under company insurance requirements
• Ability to travel throughout the Charleston metro service area
• Ability to perform the physical requirements of the position, with or without reasonable accommodation
• A suitable place to park and secure a company service truck at your residence

• ASE Medium/Heavy Truck certifications
• Class A or B Commercial Driver's License
• Qualified commercial vehicle or brake inspector credentials
• Experience with air brakes, trailers, hydraulics, liftgates, welding, or fabrication
