Heavy Diesel Mechanic

White and White Contracting, LLC (W&W) is a heavy civil underground utility contractor based in the East Valley of the greater Phoenix Metro area. We self-perform a broad scope of underground utility work, including wet and dry utilities, sewer and water systems, storm drain, fireline, site electrical, pipeline replacement, CIPP lining, jack and bore, and bypass pumping. We run multiple crews across active jobsites throughout the Phoenix metro area at the same time, every day — which means our equipment fleet cannot afford to sit idle. A single machine down on any given site can stall a crew, push back schedules, and put production deadlines at risk. Keeping our excavators, loaders, backhoes, and support equipment running reliably isn't a back-office task — it's mission-critical to our ability to deliver on every active jobsite simultaneously. We need a mechanic who understands that urgency and treats fleet uptime as the top priority it is. POSITION OVERVIEW: We are looking for an experienced Lead Heavy Diesel Equipment Mechanic to take ownership of our equipment fleet — combining hands‑on diagnostic and repair expertise with fleet management responsibility across multiple active jobsites (Buckeye, Peoria, Phoenix, Chandler, Queen Creek, Maricopa). This is a hybrid role: part senior technician, part fleet manager. You'll keep roughly 75 units — excavators, loaders, backhoes, water trucks/towers, rollers, trucks/trailers, and support equipment — running reliably, while building the systems, vendor relationships, and reporting that turn maintenance from reactive to predictive. You'll work directly with our Operations Manager, General Superintendents, and Foremen, and communicate effectively with our bilingual (English/Spanish) crew.
