Power Generation Field Service Specialist

Picture your workday starting in the shop with a quick review of service tickets, then heading into the field to bring critical power systems online. By mid-morning you’re performing a load test on a commercial gen-set; in the afternoon you’re diagnosing an ATS issue at a data center and wrapping up with clean, accurate service documentation.
