BSEE specializing in Power Systems or Electrical Engineering from an ABET-accredited university; MS and PE license are a plus.
Demonstrated experience owning engineering scope for HV substations, MV distribution systems, transmission lines, utility interconnections, transformers, switchgear, protection and control, SCADA, and telecommunications.
Strong understanding of electrical infrastructure required to power large hyperscale and AI data center campuses, including utility service, HV substations, MV distribution, redundancy architectures, backup generation, and BESS/UPS.
Experience working with utilities and ISO/RTO interconnection requirements for large electrical loads, including power quality, voltage and frequency, reactive power, power factor, harmonics, protection, stability, and load-ramping requirements associated with large AI loads.
Strong knowledge of HV/MV electrical system studies, including load flow, short circuit, transient/dynamic stability, protection coordination, grounding, arc flash, harmonics, power quality, and reliability/availability studies.
Strong knowledge of substation protection and control, SCADA, communications, metering, relay coordination, and utility protection requirements.
Experience developing and reviewing electrical one-lines, substation layouts, protection philosophies, equipment specifications, grounding designs, cable systems, and detailed engineering packages.
Experience developing and implementing N+1, 2N, and other high-reliability electrical architectures for mission-critical facilities and large data center loads.
Experience integrating utility power, gas generation, BESS/UPS, renewable generation, and other distributed energy resources into complex electrical systems.
Demonstrated ability to take ownership of technical scope, drive engineering deliverables, coordinate multiple stakeholders, identify design issues, and bring complex electrical problems to resolution.
Ability to provide technical direction to engineering consultants, EPCs, OEMs, and contractors while working closely with the HV Lead Engineer and broader project team.
Strong engineering, technical communication, coordination, and problem-solving skills, with the ability to work independently and make sound technical decisions within assigned scope.
Ability to multi-tasking and manage multiple concurrent projects and effectively coordinate with multidisciplinary engineering, construction, operations, utility, and data center teams.
