Electrical Power Generation Engineer (Substation, MV & LV power) - Data Center Operations (on-site Nashville, TN)

Role Overview

This position will be full-time on-site at Oracle's offices located in Nashville, TN .  Relocation assistance may be available in accordance with Oracle’s relocation policies. Candidates should expect a minimum of 25% travel , with additional travel as business needs require.<<

The Electrical Power Generation Engineer provides technical leadership for the design, delivery, commissioning, and operational readiness of mission-critical data center power infrastructure. The role requires extensive knowledge of grid substations, medium-voltage (MV) and low-voltage (LV) distribution equipment, power quality monitoring, power-generation systems, protective relaying, switchgear, transformers, and related electrical infrastructure.

This engineer works cross-functionally with design, engineering, construction, delivery, commissioning, and operations teams from project inception through final handover to ensure the power-generation infrastructure is safe, resilient, maintainable, scalable, and aligned with data center availability objectives.

Responsibilities

Key Responsibilities Serve as the electrical power-generation subject-matter expert across concept development, detailed design, construction, commissioning, operational handover, and lifecycle support. Define electrical design criteria, system architecture, capacity, redundancy, reliability, maintainability, grounding, protection, and operational-readiness requirements. Lead design and technical reviews for grid substations, utility interconnections, high-voltage and medium-voltage substations, transformers, switchgear, breakers, protection relays, cables, grounding, metering, and communications interfaces. Design and review MV and LV electrical distribution systems, including MV switchgear, transformers, LV switchboards, motor-control centers, panelboards, distribution boards, UPS interfaces, automatic transfer switches, and busway systems. Review electrical interfaces for generator systems, generator step-up transformers, generator breakers, paralleling switchgear, load banks, and associated balance-of-plant electrical equipment. Establish and validate power-system operating strategies, including utility transfer, generator paralleling, power quality monitoring, load shedding, restoration, emergency operations, and failover scenarios. Coordinate utility-interconnection requirements, including protection coordination, relay settings, anti-islanding, transfer-trip, telemetry, metering, energization plans, and operating agreements. Perform or review short-circuit, load-flow, arc-flash, harmonic, grounding, voltage-drop, and protective-device coordination studies. Review electrical one-line diagrams, schematics, protection diagrams, equipment specifications, cable schedules, vendor submittals, and construction-installation packages. Collaborate with mechanical, I&C, network, controls, construction, delivery, commissioning, and operations teams to ensure coordinated, buildable, testable, and maintainable solutions. Develop and support commissioning plans for substation energization, equipment startup, relay testing, switchgear testing, generator testing, load-bank testing, integrated systems testing, and utility-transfer tests. Lead root-cause analysis of electrical faults, protective trips, power-quality events, equipment failures, and recurring operational issues. Develop electrical operating procedures, maintenance strategies, emergency-response plans, spare-parts recommendations, and lifecycle replacement plans. Ensure complete turnover documentation, including as-built drawings, relay settings, test reports, commissioning records, equipment manuals, training materials, warranties, and asset records. Support operations through periodic testing, outage planning, capacity upgrades, maintenance optimization, and continuous reliability improvement. Ensure compliance with applicable electrical safety, utility, environmental, and regulatory requirements. Required Qualifications Bachelor’s degree in Electrical Engineering, Power Systems Engineering, or a related engineering discipline. 10+ years of experience with utility substations, grid interconnection, MV and LV electrical distribution systems, and mission-critical or industrial power infrastructure. Strong knowledge of MV switchgear, LV switchboards, transformers, protective relays, generators, paralleling switchgear, UPS systems, ATS equipment, and electrical distribution equipment. Experience performing or reviewing short-circuit, load-flow, arc-flash, grounding, harmonic, and protection-coordination studies. Demonstrated experience delivering electrical infrastructure from design through construction, commissioning, and operational turnover. Ability to interpret and develop electrical one-line diagrams, control schematics, protection diagrams, equipment specifications, and commissioning procedures. Strong cross-functional coordination, troubleshooting, technical writing, vendor-management, and communication skills. Ability to support 24/7 critical operations, planned maintenance windows, and emergency-response events. Preferred Qualifications Experience with hyperscale or enterprise data centers, microgrids, utility-scale power systems, or high-voltage substations. Familiarity with IEEE, IEC, NFPA 70, NFPA 70E, NEC, NESC, NETA, OSHA, and applicable utility-interconnection standards. Experience with SEL, GE, Siemens, ABB/Hitachi Energy, Schneider Electric, Eaton, and Vertiv UPS systems and equipment. Professional Engineer license, NETA certification, or equivalent power-systems credential. Why Oracle Cloud Infrastructure?
