About the Job

Requirements

  • A bachelor's degree in electrical engineering, computer engineering, physics, or another engineering discipline is required.
  • At least 8 years of experience in power systems engineering is required.
  • At least 4 years of direct experience with utility-scale or large commercial and industrial battery energy storage is required.
  • Candidates must be able to perform hands-on work in heat, cold, rain, tight quarters, or at heights.
  • Candidates must be able to work extended hours and weekends as needed for construction, energization, and operations.
  • Candidates must remain focused in hazardous environments while wearing appropriate personal protective equipment.
  • Candidates must be able to lift up to 25 pounds unassisted.
  • Candidates must provide 24/7 on-call support for emergencies.
  • Candidates must be willing to work on-site in Memphis, Tennessee; the role is not remote or hybrid.
  • Candidates must be willing to travel up to 25% for factory witness testing, vendor and original equipment manufacturer engagement, and supporting other sites.
  • A valid driver's license is required.

Responsibilities

  • Own the storage fleet as a power plant, including architecture, sizing, controls, the safety case, and grid-forming behavior that allows the campus to ride through compute step loads and generation contingencies.
  • Own battery energy storage system architecture, including pack-to-medium-voltage transformer grouping, string composition, medium-voltage collection topology, string-level protection, and physical block layout with spacing per NFPA 855.
  • Translate compute duty cycles, including step loads, training-job ramps, and actual-versus-nameplate utilization, into power and energy requirements.
  • Own inverter control strategy, including grid-forming versus grid-following operation, droop and virtual inertia, fault-current contribution, ride-through, and coordination with generation governors and excitation.
  • Own the plant controller and energy management system functional specification for dispatch, state-of-charge management, peak shaving, spinning-reserve emulation, islanding, and black-start participation.
  • Own the fire and life-safety case, including the UL 9540 and 9540A basis, thermal runaway propagation, deflagration venting, water supply, the emergency response plan, and authority having jurisdiction engagement.
  • Own the original equipment manufacturer relationship, including technical requirements, factory testing, performance guarantees, and degradation and augmentation planning.
  • Direct design, commissioning, operations/build, network, civil, and program manager seats on battery storage as those seats fill.

Desired Qualifications

  • Experience sizing storage against a real duty cycle rather than using a rule of thumb.
  • Working knowledge of NFPA 855, UL 9540 and 9540A, IEEE 1547, and IEEE 2800.
  • Utility-scale battery energy storage system fleet experience at large pack counts.
  • Deep understanding of grid-forming inverter control and its interaction with synchronous machines.
  • Experience using PSCAD or other electromagnetic transient modeling of inverter-based resources.
  • A Professional Engineer license or intention to actively seek one.
  • Experience building and leading an engineering team from the first hire.
