• Liaison Duties: Translate technical jargon from diesel mechanics into clear, understandable terms for the customer.
• Repair Updates: Keep owner-operators and fleet managers informed of repair statuses, unexpected delays, or necessary additional repairs requiring authorization.
• Documentation & Invoicing: Maintain detailed, accurate records of all customer interactions, authorizations, DOT inspection documentation, and final repair details. Review and close out final invoices.

Requirements:

 

• Experience: 2+ years of experience as a Service Advisor/Writer, preferably in a diesel, heavy-duty truck, or commercial fleet environment.
• Technical Knowledge: Strong working knowledge of diesel engines (e.g., Cummins, Paccar, Detroit, Volvo-Mack, Powerstroke, Duramax) and heavy-duty truck systems (air brakes, aftertreatment systems, heavy suspensions).
• Software Proficiency: Experience with shop management and scheduling software (e.g., Fullbay, Mitchell1, or similar platforms).
• Customer Service Skills: Excellent verbal and written communication skills with a proven ability to manage frustrated customers and negotiate service sales.
• Attention to Detail: Ability to accurately track complex parts orders, warranty claims, and multiple fleet accounts simultaneously.

Preferred Skills

• Familiarity with DOT regulations and compliance inspections.
• Existing relationships with local heavy-duty parts vendors.
• ASE Certification (Service Consultant) is a strong plus.
