Diesel Technician (Medium & Heavy-Duty)

If your output is higher than everyone else in your shop—your environment should reflect it.

At ACTS Fleet, we built this role for experienced diesel technicians who know their craft, take pride in their work, and want to work in a shop where performance, structure, and respect actually align.

What Makes This Different

High-performing technicians shouldn’t be held back by the environment around them.

At ACTS Fleet, everything is built on two principles: clear expectations and trust in execution.

What that looks like:

  • Structured processes and consistent standards across the board
  • Direct, clear communication with leadership
  • The autonomy to do your job—without micromanagement

The Work

You’ll work on medium and heavy-duty commercial trucks and fleet vehicles—both in-shop and in the field—with a focus on uptime, safety, and getting repairs done right the first time.

Day-to-day responsibilities include:

  • Preventative maintenance (DOT inspections, fluids, filters, brakes)
  • Diagnosing and repairing diesel engines
  • Advanced diagnostics on late-model trucks
  • Brake systems, suspension, steering, driveline, and transmissions
  • Electrical systems and emissions components
  • Reading fault codes and diagnostic data accurately
  • Verifying repairs through inspections and test drives

Mobile Service Work:

  • Diagnose and repair equipment directly in the field
  • Work independently with a high level of ownership
  • Represent ACTS Fleet with professionalism and reliability

What You Bring

  • Strong hands-on experience as a diesel technician
  • Advanced diagnostic ability
  • Familiarity with OEM and aftermarket scan tools
  • Ability to work independently and follow structured processes
  • Clear communication and accountability
  • CDL preferred, not required

This role is built for technicians who:

  • Handle complex diagnostics without relying on others
  • Take ownership of their work—shop or field
  • Prefer working in an environment with consistent standards
  • Want autonomy without chaos
