Batch Plant Operator

JOB SUMMARY

The Plant Operator is responsible for the safe and efficient operation of a ready-mix concrete batching facility. Under the direction of plant leadership, the Operator will learn to utilize computer-controlled systems to proportion raw materials into ready-mix trucks according to specific mix designs. This role is a blend of technical system monitoring and hands-on physical labor, requiring a high commitment to safety, quality control, and environmental compliance. Beyond technical batching, this role serves as a central hub for plant activities—coordinating with dispatch for delivery schedules, maintaining precise material inventories, and performing routine inspections to ensure maximum production uptime. The Operator is expected to maintain an uncompromising focus on safety, environmental compliance, and product quality while fostering a professional relationship with drivers and customers.
