About the role

Protect, design, commission, and maintain protection and control systems for large electrical infrastructure, from utility interconnection through facility buses, including on-site generation and battery energy storage; based in Memphis, TN with potential travel.

Responsibilities

  • Develop protection philosophy, one-line and three-line diagrams, DC control schematics, wiring diagrams, and relay panel layouts for the electrical system from the utility interconnection to facility buses.
  • Calculate, implement, and maintain protective relay settings and logic for transmission lines, buses, power transformers, distribution feeders, generators, and battery energy storage / inverter-based resources.
  • Specify relays, current and voltage transformers, trip circuits, lockout schemes, breaker-failure protection, and communications-assisted schemes (permissive, blocking, transfer trip).
  • Perform short-circuit, protective-device coordination, and arc-flash studies; keep settings aligned with the study of record as the system changes.
  • Commission protection systems: functional checks, primary and secondary injection, end-to-end scheme tests, and in-service timing checks. Use industry test sets (e.g. Doble, Omicron).
  • Collect and analyze fault and disturbance records (COMTRADE and equivalent); recommend setting or scheme changes after events, misoperations, or staged tests.
  • Maintain the settings management database, as-left files, and firmware/config control for in-service relays.
  • Integrate protection with SCADA, RTUs, and plant/facility monitoring: DNP3, Modbus, IEC 61850 (including GOOSE), and IEEE C37.118 synchrophasors as applicable.
  • Support NERC PRC evidence and testing where the interconnection or generation/storage fleet requires it (e.g. PRC-005, PRC-019, PRC-024, PRC-027).
  • Work with field technicians, operators, and contractors during outages, switching, and troubleshooting. Stay hands-on at the panel.
  • Apply IEEE C37 (including line, transformer, bus, and generator protection), NESC, NFPA 70 / 70E, IEEE 1547, and IEEE 2800 as they apply to the assets in scope.

Qualifications

  • Bachelor's degree in electrical engineering, computer engineering, or another engineering discipline.
  • 3+ years of protection and controls experience (settings, design, or commissioning) on medium- or high-voltage systems.
