Field Service Diesel Mechanic

Field Service Technician – Mobile 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.

Position summary

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.

What you'll do

• 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.

Safety standards and skills

• 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.

Who you are

• 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.
• Always learning. Equipment keeps getting more complex, and you keep your skills current.

Qualifications

Required

• High school diploma or equivalent
• 2–3 years of automotive or diesel repair experience
• Ability to diagnose, repair, and overhaul large equipment in the field
• Valid driver's license with a clean driving record

• Ability to lift 50+ pounds, bend, twist, and squat, and work outdoors in heat and cold
• Availability for overtime, emergency call-outs, weekends, and holidays
• Ability to pass a pre-employment drug screen, background check, MVR check, and DOT compliance screening

Preferred

• CDL Class A or B
• Bilingual in English and Spanish
• Associate degree or certification in diesel technology
• Experience with Altec, Terex, Freightliner, Cummins, or Allison equipment
• Experience with aerial devices, hydraulics, or tree care equipment

What we offer

• Full-time, steady work with a growing company
• Full benefits
• Starting at $30.00 per hour, based on qualifications and experience

A day in the role

No two days are the same. You might start with scheduled preventive maintenance at a yard, then get a call that a bucket truck has a hydraulic leak on a right-of-way an hour away. Much of your day is spent driving between sites, and the rest is hands-on work outdoors in a non-climate-controlled setting.

Shifts run a standard 8- or 10-hour day, with overtime, emergency call-outs, and storm response as needed. When travel takes you far from home, you'll stay overnight on per diem or in a company-provided hotel.
