• Service and repair lift gates and light hydraulic systems associated with trailers and fleet equipment.
• Work through a daily queue of approximately 2045 driver write-ups, prioritizing work effectively to keep the fleet operating safely and efficiently.
• Delegate repairs and assist other technicians as needed to maximize shop productivity and ensure timely completion of work orders.
• Perform tire repairs and replacements as needed, accounting for approximately 1015% of the workday.
• Support refrigeration unit maintenance on Thermo King systems when applicable, especially if you bring reefer experience.
• Apply fleet maintenance best practices to maintain a high standard of safety, reliability, and compliance.
• Demonstrate a leadership mentality by helping direct shop workflow and serving as a technical resource for other technicians.
• Maintain accurate documentation of repairs, inspections, and preventive maintenance activities in accordance with company and regulatory standards.

• Proven experience as a diesel technician working on heavy-duty trucks and fleet equipment.
• Strong diagnostic skills in diesel systems, including engines, electrical, and mechanical components.
• Hands-on experience performing maintenance and repairs on Mack, Volvo, and Freightliner trucks.
• Ability to diagnose and repair electrical, wiring, and sensor-related issues using wiring diagrams and schematics.
• Proficiency with OEM diagnostic programs and tools for diesel equipment.
• Experience troubleshooting and repairing Detroit DD13 and DD15 engines or similar heavy-duty diesel engines.
• Background in fleet maintenance, including preventive maintenance and repair planning.
• Experience with trailer repair, including components on Hyundai Translead and Great Dane trailers or similar equipment.
• Ability to perform medium-duty engine repairs, particularly sensor-related and similar repairs typically completed in 24 hours.
• Experience with light hydraulic systems, including lift gates and related equipment.
• Mechanical aptitude in diesel, hydraulics, brakes, transmissions, and heavy equipment systems.
• Competence in tire repair and replacement on commercial vehicles.
• Understanding of DOT-related requirements as they pertain to commercial vehicles and fleet maintenance.
• Leadership mentality and ability to help direct shop workflow and support other technicians.
• Valid CDL Class A or CDL Class B license.
• Strong troubleshooting skills and the ability to work efficiently through multiple driver write-ups each day.

• Experience with Thermo King refrigeration units; candidates with reefer experience may qualify for higher compensation.
• Experience with small engine repair is beneficial.
• Previous experience working in a multi-bay diesel shop environment.
• Familiarity with Class 8 equipment and some Class 4 and Class 5 units.
• Comfort working with both mechanical and electrical systems, including brake and transmission components.
• Ability to collaborate effectively with a team and contribute to a culture based on integrity.
• Strong organizational skills to manage a high volume of work orders and driver write-ups.
• Commitment to safety, quality workmanship, and adherence to company and regulatory standards.
