Maintenance Supervisor

Under the direction of the Maintenance Manager, the Maintenance Supervisor will oversee the day-to-day operations of a maintenance department and the supervision of a team responsible for the preventive maintenance and repair of fleet. Ensure all repairs and/or maintenance to equipment (diesel fleet, alternate fuel, containers, and other heavy-duty equipment) is performed in accordance with Company safety and compliance standards, and with all federal/state regulations.

Position Overview

Are you a skilled diesel mechanic who has proven experience turning wrenches on the shop floor and stepping up to lead others? We are looking for an experienced Maintenance Supervisor to run our evening shift operations at our primary shop location while providing leadership oversight across two additional local satellite sites.

In this role, you’ll bridge the gap between hands-on technical troubleshooting and strategic shop management. You’ll keep our fleet safe, reliable, and compliant, lead and mentor a team of technicians, and ensure high-efficiency throughput during peak operational hours.

Key Responsibilities

• Evening Operations Leadership: Oversee daily planning, scheduling, and execution of all repair work (2:00 PM – 12:00 AM) to optimize shop productivity across the main hub and two local satellite facilities.
• Team Supervision & Coaching: Supervise, train, coach, and evaluate shop personnel. Provide direct input into hiring, performance reviews, disciplinary actions, and promotions.
• Hands-on Support & Diagnostics: Perform advanced diagnostics on complex heavy-duty diesel, alternate fuel, hydraulic, electrical, engine, brake, and emission systems. Assist technicians on the floor and conduct road tests as needed.
• Quality & Safety Control: Conduct daily shop huddles, fleet walks, and Quality Control Inspections (QCIs). Inspect outside vendor repairs to guarantee full compliance with DOT, OSHA, and company safety standards.
• Work Order & Inventory Management: Plan and schedule repairs using maintenance software (M5 planner), procure parts, track inventory, and maintain accurate records of preventive/corrective maintenance and payroll.
• Budget & Expense Management: Assist in budget preparation, monitor shop expenses, approve routine purchase orders, and refer major component repairs or large expenses to the Maintenance Manager.
