Ready Mix Driver

JOB SUMMARY

The Mixer Driver is a critical member of the Martin Marietta team, responsible for the safe and efficient operation of a ready-mix concrete truck. The driver is tasked with the high-stakes delivery of perishable concrete products from plant locations to diverse customer job sites. This role requires more than just driving; it involves technical quality control (slump testing), equipment maintenance, and serving as the primary face of the company to contractors and clients. The objective is to maintain a "Safety First" culture while ensuring the highest level of customer service and product integrity.

KEY DUTIES AND RESPONSIBILITIES

Operate heavy-duty ready-mix trucks in compliance with all DOT, state, and federal regulations, as well as Martin Marietta's rigorous safety standards. Exercise expert judgment when accessing job sites to avoid hazards (soft ground, overhead wires, or tight clearances) and ensure the safest position for unloading. Assemble concrete chutes and operate hydraulic chute controls during the pour. Coordinate with site crews to ensure the concrete is placed exactly where needed. Work closely with the Dispatch team to determine the quickest and safest routes, minimizing "time in drum" to preserve concrete quality. Visually inspect the concrete mix for "slump" (consistency) and load size before leaving the plant and upon arrival at the job site. Maintain the mixer in a clean, organized, and professional condition. This includes using water hoses to clean the mixer drum and truck exterior between loads to prevent concrete buildup. Perform comprehensive pre-trip and post-trip vehicle inspections (tires, lights, fluids, brakes). Document and report any mechanical issues or unsafe conditions immediately. Perform minor roadside repairs or assist maintenance teams with larger mechanical fixes as required. Act as a brand ambassador, maintaining a professional appearance and a courteous, "can-do" attitude when interacting with customers and the public. Manage delivery tickets accurately, ensuring all necessary documentation is signed and returned to the plant to facilitate billing. Communicate effectively with coworkers via two-way radio, hand signals, or verbal instruction to ensure smooth operations at the plant and site. Demonstrate working knowledge of OSHA, DOT, and EPA regulations. Strictly follow Lock Out/Tag Out (LOTO) procedures when performing maintenance. Consistently wear all required safety gear (hard hat, safety glasses, steel-toed boots, high-visibility vest) and attend mandatory safety meetings.
