The pace is generally steady, with a focus on identifying candidates who can thrive in the high-stakes, mobile environment of our service department.

Mechanical Diagnostics

We look for a systematic approach to troubleshooting. Strong candidates can explain their process for isolating issues in complex systems without jumping to conclusions.

Be ready to go over:

• Engine Systems – Understanding fuel delivery, air intake, and exhaust after-treatment.
• Electrical Troubleshooting – Using multimeters and diagnostic software to trace faults.
• Hydraulics and Pneumatics – Basic principles and common failure points in commercial vehicles.

Field Logistics

The ability to manage a service vehicle and a remote workflow is what separates a good mechanic from a great Mobile Engineer.

Be ready to go over:

• Inventory Management – How you keep track of parts and supplies.
• Time Management – Balancing travel time with repair time effectively.
• Documentation – The importance of accurate and timely service reporting.

As a Mobile Engineer, your primary objective is to deliver high-quality service at the customer's site. You will spend the majority of your time traveling between locations, performing diagnostics, and executing repairs on various heavy-duty trucks. You will need to collaborate closely with parts departments to ensure you have the necessary components before arriving at a job site, minimizing the need for return trips.

Beyond the technical work, you are responsible for maintaining the integrity and organization of your service vehicle. You will act as a consultant to the customer, providing clear updates on repair status and professional advice on preventative maintenance. This role requires a high degree of accountability, as you are the primary point of contact for the customer’s vehicle health while on-site.

We are looking for candidates who possess a solid foundation in diesel mechanics and the drive to work independently.

• Must-have skills:
  • Proven experience as a diesel mechanic or technician.
  • Proficiency with diagnostic software and tools.
  • A clean driving record and the ability to operate a service vehicle.
  • Strong troubleshooting skills for electrical and mechanical systems.
• Nice-to-have skills:
  • Manufacturer-specific certifications (e.g., Freightliner, Cummins).
  • Experience in a field-service or mobile repair role.
  • Advanced knowledge of modern emission control systems.

Q: How can I best prepare for the technical portion of the interview? Focus on reviewing the specific engine platforms and diagnostic tools you have used in your previous roles. Be prepared to talk through a "difficult" repair you performed, explaining the symptoms, your diagnostic path, and the final fix.

Q: What is the company culture like for the field team? The team is highly professional and values independence, accountability, and safety. We support our Mobile Engineers with the resources they need to succeed, but we expect them to take ownership of their daily operations.

Q: Is there a typical timeline for the hiring process? The timeline can vary, but Premier Truck Group generally aims to move through the interview stages efficiently once a strong candidate is identified. You can expect clear communication regarding next steps throughout the process.

• Showcase your reliability: Emphasize your track record of punctuality and meeting service deadlines.
• Prepare for "What-If" scenarios: Think about how you would handle an unexpected part failure or a customer dispute in the field.
• Highlight your safety record: Safety is non-negotiable; mention any safety training or protocols you have strictly followed in the past.
• Research the location: Understand the specific types of trucks and fleets serviced at the branch you are applying to.

The Mobile Engineer role at Premier Truck Group offers an excellent opportunity to apply your technical skills in a dynamic, high-impact environment.
