HIRING NOW

IF IT’S DIESEL, HEAVY-DUTY, AND BUILT TO WORK...

NETC Fleet Services is growing our Lee, NH operation, and we’re looking for Diesel Technicians across multiple skill levels — from recent trade-school graduates and apprentices to experienced diesel mechanics who know their way around serious equipment.

If you want challenging work, strong earning potential, and a place where your skills can keep growing, pull up a toolbox.

FROM $20/HR TO $40/HR

AND ROOM TO EARN EVEN MORE.

UP TO $120,000/YEAR

Potential total earnings for top-performing technicians

Whether you’re starting your career or bringing years of diesel experience to the shop, there’s room here to build something bigger.

JUST GRADUATED FROM DIESEL SCHOOL?

GOOD. LET’S PUT THAT TRAINING TO WORK.

Everybody starts somewhere.

If you recently completed a diesel, automotive, or technical trade-school program, we want to hear from you.

You don’t need 10 years in a shop to have potential.

You need:

A strong mechanical foundation

The willingness to learn

The work ethic to keep improving

Attention to detail

The drive to become a great technician

You’ll get exposure to real commercial equipment, real diagnostics, and real repairs while continuing to build the skills that turn a trade‑school education into a career.

You bring the foundation.

Now build the experience.

WHAT YOU’LL WORK ON

You won’t spend every day doing the same repair.

Our fleet gives you the opportunity to work across a range of equipment and systems, including:

Tow Trucks

Heavy-Duty Wreckers

Recovery Vehicles

Commercial Vehicles

Gas & Diesel-Powered Equipment

From routine maintenance to computer-aided diagnostics and major repairs, there’s always something to solve.

Troubleshoot mechanical, electrical, engine, and drivability issues

Repair or replace major components, including engines, transmissions, steering systems, and braking systems

Diagnose, service, and repair air brake systems

Communicate professionally with technicians, service staff, and customers when needed

Keep your bay, tools, and work areas clean, organized, and safe

Take ownership of the repair from diagnosis to completion

DON’T JUST CHANGE THE PART.

FIND THE PROBLEM.

Anybody can read a fault code.

A technician wants to know why it’s there.

What failed?

What caused it?

What else needs to be checked?

What repair actually solves the problem?

We value technicians who develop a diagnostic mindset — using scan tools, electrical testing, technical information, mechanical knowledge, and good judgment to find the root cause.

Diagnose it.

Build the repair plan.

Fix it right.

WHAT YOU BRING

Because we’re hiring across experience levels, we’re looking at ability, training, experience, and potential.

High school diploma or GED
