  • Track PM compliance and downtime metrics through the CMMS
  • Maintain spare parts inventory for high-failure-risk components to minimize downtime during breakdowns

  • Support budget planning for maintenance capital and operating spend

• Cross-Functional Coordination

  • Work with Plant Manager and Dispatch to minimize maintenance-driven downtime during peak pour schedules

  • Report plant condition, downtime trends, and capital needs to regional/national leadership

• Required Qualifications

  • Strong working knowledge of batch plant systems: aggregate handling, weigh batching, cement/water metering, and batching control software
  • Direct experience managing a rolling stock or heavy equipment repair shop, including mixer truck fleets (diesel engine, hydraulics, chassis, and drum systems)
  • Electrical troubleshooting ability (motor controls, VFDs, PLCs a plus) and mechanical troubleshooting (conveyors, gearboxes, pneumatics, hydraulics)
  • Demonstrated ability to lead a hands-on trades team, not just manage from a desk
