Field Service Diesel Diagnostic Technician

Transwest Mobile Truck & Trailer
Las Vegas, NV Other
POSTED ON 10/16/2026
AVAILABLE BEFORE 11/14/2026
Day in the Field — Las Vegas, NV

Your morning starts with a work order on your tablet and a fully stocked company take-home vehicle in your driveway. You head to a customer site, connect diagnostic tools to a diesel powerplant, and quickly pinpoint an electrical fault. By midday, you’re checking brake and suspension components on a light-duty diesel, then moving on to a hydraulic issue on heavy equipment. You wrap up by documenting your work and walking the client through what you found—leaving them confident and back in operation. That’s a typical day as our Field Service Diesel Diagnostic Technician.

What You’ll Tackle
  • Diagnose and repair electrical systems on diesel engines and heavy equipment.
  • Perform engine performance and drivability evaluations to ensure optimal operation.
  • Service and repair diesel engine systems, including light vehicle diesel platforms.
  • Inspect and maintain brake and suspension systems for safety and reliability.
  • Conduct detailed inspections of suspension and steering components.
  • Troubleshoot and resolve issues in hydraulic systems and components.
  • Leverage diagnostic equipment and software to identify root causes and implement solutions.
  • Restore functionality by repairing mechanical systems and components.
  • Keep precise records of services performed and parts used.
  • Communicate findings clearly and provide excellent customer service in the field.
What You Bring
  • Proven experience as a mobile diesel technician or comparable field role.
  • Advanced knowledge of electrical diagnostics and repair.
  • Hands-on expertise with engine performance and drivability assessments.
  • Familiarity with diesel engine systems, including light vehicle diesel engines.
  • Background working with brake, suspension, and steering systems.
  • Proficiency troubleshooting hydraulic systems and related components.
  • Ability to diagnose and repair mechanical systems and assemblies.
  • Exceptional problem-solving skills and high attention to detail.
  • Clear, customer-focused communication style.
  • Valid driver’s license with a clean driving record.
How You’ll Work

This is a field-based position serving customers across the Las Vegas, NV area. You’ll operate primarily at customer and job sites rather than a single facility and will be based within driving distance of the territory, traveling in a company take-home vehicle. Expect day-shift hours with weekends off.
