Job description

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.

Your experience should matter. Your efficiency should matter. And as your skills grow, your earning potential should have room to grow with them.

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

What You’ll Do

• Diagnose diesel and commercial vehicle problems using modern diagnostic equipment and software.
• 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.
• Develop repair plans after identifying the root cause of the problem.
• Perform preventive maintenance and scheduled services.
• Handle routine work including oil changes, brake checks, wheel and tire service, balancing, and alignments.
• Maintain accurate records of repairs, serviced vehicles, and parts.
• Document your findings and completed work clearly.
• 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?

What You Bring

• High school diploma or GED
• Diesel, automotive, or related technical training and/or hands-on mechanical experience
• Understanding of gas and diesel engine systems
• Familiarity with automotive or commercial vehicle electrical systems
• Ability — or willingness to learn — to use diesel diagnostic software and scan tools
• Comfortable using mechanical and electrical tools
• Strong troubleshooting and problem-solving skills
• Attention to detail
• Basic computer skills
• Clear communication and teamwork
• Valid driver’s license
• The willingness to keep learning, improving, and taking on more

The Full Package

• $20–$40/Hour Based on Experience
• Efficiency Incentive
• Earning Potential Up to $120,000/Year
• Relocation Assistance for Qualified Candidates
• Recent Diesel Trade-School Graduates Encouraged to Apply
