Responsibilities

• Lead electrical engineering activities for large-scale, mission-critical data center power projects, including on-site generation (engines, turbines, solar PV) and storage, substations, utility interconnections, microgrids, and medium- and high-voltage distribution systems.
• Develop and document the electrical basis of design based on customer requirements, anticipated data center load profiles, reliability objectives, utility requirements, project phasing, equipment capabilities, and contractual performance guarantees.
• Develop conceptual and preliminary electrical designs, including one-line diagrams, electrical site layouts, generation and distribution configurations, substations, collector systems, auxiliary power, station service, grounding, lightning protection, and protection, control, metering, and communications architectures.
• Establish design criteria for reliability, redundancy, availability, maintainability, system stability, fault-current capability, load acceptance, transient response, black-start capability, and phased load growth.
• Perform or oversee load flow, short-circuit, protection coordination, arc-flash, motor-starting, harmonic, grounding, cable ampacity, transient-stability, reactive-power, voltage-control, and generator or inverter-resource integration studies.
• Develop technical requirements and procurement specifications for substations, transformers, switchgear, generators, energy storage systems, protective relays, instrument transformers, conductors, bus systems, grounding systems, auxiliary systems, and other electrical balance-of-plant equipment.
• Support technical evaluation of equipment availability, performance, delivery schedules, commercial exceptions, warranties, testing requirements, and long-term service considerations.
• Lead or support utility interconnection applications, system-impact studies, facility studies, interconnection agreements, and coordination with utilities, independent system operators, transmission providers, and authorities having jurisdiction.
• Review customer load data and transient load profiles to confirm that proposed generation and storage systems can support steady-state and dynamic load conditions.
• Provide technical oversight and quality control of third-party engineers of record, including review of studies, calculations, drawings, specifications, equipment schedules, and issued-for-construction documents.
• Facilitate electrical design reviews, constructability reviews, hazard assessments, technical workshops, and customer presentations.
• Review commissioning procedures and test results for generators, transformers, switchgear, protective relays, controls, battery systems, and electrical balance-of-plant equipment.
• Perform other duties as required.
