JBS Auto Service is an independent automotive repair shop specializing in light-duty diesel pickup truck repair and maintenance. About 80% of our workload is diesel pickups, including Powerstroke, Duramax, and Cummins trucks.

We are not a medium-duty or heavy-duty diesel shop. We do not work on semis, buses, big rigs, or over-the-road trucks. Our focus is diesel pickup diagnostics, maintenance, and repair.

We are looking for an experienced, certified, or dealership-trained diesel technician who wants steady diesel pickup work, a strong independent shop environment, and no weekends.

This is a great opportunity for a Ford, GM, or Ram diesel technician who is tired of the dealership grind, warranty time, Saturdays, and corporate pressure, but still wants to do high-quality diesel work in a professional shop.

The ideal candidate will have strong experience with one or more of the following platforms:

• Ford Powerstroke

You do not need to be an expert in all three brands, but strong diesel pickup experience is important. Ford, GM, Ram/Stellantis, Cummins, or ASE certifications are strongly preferred.

• Use scan tools, diagnostic equipment, service information, and proper testing procedures.
• Perform digital vehicle inspections accurately and thoroughly.
• Document findings, test results, recommendations, parts used, and repairs performed.
• Communicate clearly with service advisors and other technicians.
• Maintain a clean, safe, and organized work area.
• Follow shop procedures and safety standards.

• Experience diagnosing and repairing light-duty diesel pickup trucks.
• Strong knowledge of at least one diesel platform: Powerstroke, Duramax, or Cummins.
• Ford, GM, Ram/Stellantis, Cummins, or ASE certifications preferred.
• ASE A9 Light Vehicle Diesel certification is a plus.
• Dealership diesel experience is a plus.
• Strong electrical and drivability diagnostic skills preferred.
• Experience with diesel fuel systems, turbo systems, cooling systems, and emissions systems.
• Ability to use scan tools and service information effectively.
• Ability to document repairs and recommendations clearly.
• Strong attention to detail and commitment to quality work.
• Team-oriented attitude and willingness to communicate with advisors and technicians.
• Valid driver’s license and clean driving record.

• Are a Ford, GM, or Ram diesel technician looking for a better shop environment.
• Want to work on diesel pickups without dealing with medium-duty or heavy-duty trucks.
• Are tired of warranty time, dealership politics, or weekend schedules.
• Want steady diesel pickup work in an independent shop.
• Take pride in diagnosing problems correctly the first time.
• Enjoy working on Ford Power Stroke, Chevy/GMC Duramax, and Ram Cummins trucks.
• Want to be part of a shop that is serious about growing its diesel pickup repair team.
