Power Generation Field Technician

Start your day with a service ticket and a full tank. By noon, you’ve completed a load test on a 750 kW genset, diagnosed a finicky ATS, and explained your findings to a facilities manager who now knows exactly what will keep their lights on. By evening, you’ve documented everything, prepped parts for tomorrow, and you’re ready if the on-call phone rings. If this sounds like a day you’d enjoy, read on.
