Field Service Diesel Mechanic

Keep the fleet rolling

When a bucket truck goes down on a utility right-of-way, a crew is standing still and a deadline is ticking. That's when you show up. If you'd rather be out on the road solving real problems than stuck in the same bay every day, we want you on our Fleet Services team.

We're looking for a self-motivated, hardworking diesel technician who can diagnose under pressure, fix it right the first time, and keep crews safe. You'll travel between job sites across Georgia and Tennessee area, working on Altec, Terex, Freightliner, Cummins, and Allison equipment in the field, in all kinds of weather.

The Halter Group started with local residential tree work in 1982 and has grown into a multi-faceted company providing right-of-way clearing for utility, gas, pipeline, and D.O.T. customers. More than 40 years later, we still run on the same five principles:
Integrity, Safety, Accountability, Motivation, and Respect. That is our promise to our customers and our employees. Learn more at

The Field Service Technician inspects, maintains, and repairs the trucks, trailers, aerial lifts, forklifts, pickups, and tree service equipment that keep our vegetation management crews working. This is a mobile role: you bring the shop to the equipment, handle preventive maintenance on schedule, and respond fast when something breaks down. You report directly to the Fleet Services Manager.

• Travel to job sites and yards to inspect, service, and repair diesel engines, transmissions, brakes, electrical, cooling, steering, and hydraulic systems.
• Work on aerial lifts, bucket trucks, chippers, tractors, and other tree service equipment from Altec, Terex, Freightliner, Cummins, and Allison.
• Perform scheduled preventive maintenance on heavy-duty diesel engines, pickups, trailers, and standard equipment.
• Use diagnostic tools and critical thinking to troubleshoot problems and find a solution in the field.
• Talk with crews and foremen, read work orders, and decide what's needed before you start.
• Prioritize repairs by urgency so the most critical equipment gets back to work first.
• Keep accurate service records in our fleet maintenance software.
• Track receipts and invoices for accurate, on‑time expense reporting.
• Coach field crews on preventive maintenance and daily equipment care.
• Respond to after‑hours, weekend, and holiday call‑outs when equipment goes down.
• Support storm response and other duties as assigned.

• Follow all established safety protocols and set up a safe work zone at every roadside or right‑of‑way repair.
• Lock out and tag out equipment, and safely support raised booms and hydraulic loads before working on them.
• Inspect aerial devices and safety‑critical systems so crews can trust the equipment they climb into.
• Meet DOT inspection and compliance requirements for the vehicles you service.

• Road‑ready. You like being on the move and don't mind a hotel night when the job calls for it.
• Cool under pressure. When a crew is down and everyone is waiting, you stay calm, focus, and get it fixed.
• A sharp troubleshooter. You trust your diagnostics and your instincts, and you find the root cause instead of guessing.
• Tough. Heat, cold, mud, and roadside repairs don't slow you down.
• Self‑managed. You plan your own day, prioritize the work, and follow through without being told.
• A clear communicator. You explain problems simply to crews, whether in English or Spanish, and keep your paperwork clean.
• Reliable. When the phone rings at night or on a weekend, the crews know you'll answer.
