Job Description

The Heavy Equipment Mobile Mechanic independently performs preventive maintenance, inspections, diagnostics, repairs, and emergency field service on off-highway heavy equipment and related support equipment. The mechanic travels between assigned locations and worksites, brings the right tools and parts to each job, confirms equipment is safe and operational before release, and documents labor, parts, findings, repairs, and follow-up needs in the fleet maintenance system. This position combines strong diesel, hydraulic, electrical, electronic, powertrain, brake, HVAC, and fabrication skills with sound judgment, urgency, organization, and professional communication. The role requires comfort working with limited direct supervision while remaining fully accountable to IWS Maintenance and Safety Programs.

• Operate and care for the assigned service truck. Complete required inspections; maintain tools, fluids, spill-response materials, common parts, and safe housekeeping; and report vehicle or equipment defects promptly.
• Document parts used, labor hours, meter readings, failure descriptions, cause, correction, verification, photos when required, and recommended repairs in the fleet maintenance system before closing or updating repair orders.
• Identify recurring failures, unsafe conditions, abuse or misuse concerns, and reliability opportunities. Escalate critical findings and recommend practical corrective actions.
• Perform basic welding, cutting, drilling, component removal and installation, hose or fitting replacement, and field fabrication when qualified and when conditions allow the work to be completed safely.
• Follow lockout/tagout, blocking and cribbing, fall protection, hot-work, spill prevention, PPE, traffic-control, and site-specific requirements applicable to the task.
