Lead Engineer, Battery Storage - Memphis

The role

You will act as the lead for battery storage on power systems for AI training campuses. You will own the design, sizing, controls, and fire and life-safety case of a large storage fleet, and direct the related engineering seats as they fill.

What you will do

• Own the storage fleet as a power plant: architecture, sizing, controls, safety case, and grid-forming behavior
• Own BESS architecture, including pack and string layout, medium-voltage topology, protection, and block layout per NFPA 855
• Own sizing by translating compute duty cycles into power and energy requirements
• Own inverter control strategy, including grid-forming versus grid-following, ride-through, and generator coordination
• Own the plant controller and EMS functional specification, including dispatch, peak shaving, and black-start participation
• Own the fire and life-safety case, including UL 9540 and 9540A basis, emergency response plan, and AHJ engagement
• Own the OEM relationship: technical requirements, factory testing, performance guarantees, and degradation planning
• Direct design, commissioning, operations, network, civil, and program manager seats on battery storage as they fill

Required qualifications

• Bachelor's degree in electrical engineering, computer engineering, physics, or another engineering discipline
• 8+ years in power systems engineering
• 4+ years directly on utility-scale or large commercial and industrial battery energy storage
• Perform hands-on work in all environments (heat, cold, rain), in tight quarters or at heights
• Remain focused in hazardous environments while wearing appropriate PPE
• Lift up to 25 lbs unassisted
• Valid driver's license

Nice to have

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

Before you apply

• Not a remote or hybrid role; work is on-site in Memphis, TN
• Travel up to 25%
• 24/7 on-call support for emergencies
