Advanced understanding of mechanical and electrical equipment, systems, and design for data centers, including MV/LV distribution, transformers, switchgear, UPS, STS/ATS, PDUs, VFDs, generators, chillers (air- and water-cooled), pumps, cooling towers, heat exchangers, CRAHs, air economizers, and liquid cooling. • 8+ years of direct engineering experience in a technical or critical environment (data center, hospital, pharmaceutical, semiconductor, nuclear, or industrial/commercial field engineering), including significant time supporting operating facilities rather than design/construction alone.
