Generator Maintenance Technician

Nature and Variety of Work:

The Generator Maintenance Technician performs skilled work in the maintenance, repair, modification, and preventive maintenance of diesel-electric generating equipment and related systems. Work includes servicing, diagnosing, troubleshooting, and repairing diesel engine-driven electric generators, automatic transfer switches, and associated components. Assignments are received as oral or written orders, often accompanied by sketches or diagrams, and are performed with considerable independence within established policies, procedures, and technical guidelines.

Because project locations are situated in different areas of the country, regular travel is required. There is also the opportunity for cross-training in HVAC, chillers, mechanical systems, and boilers to support broader service capabilities.
