Lead Engineer (Battery Storage)

Join the High Power Engineering team at SpaceXAI to design, build, operate, and maintain electrical infrastructure for AI training campuses. As a Lead Engineer for Battery Storage, you will work on-site in Memphis, TN, with a small team to scale high-capacity power systems according to compute demand.

Responsibilities:

• Lead the storage fleet as a power plant, focusing on architecture, sizing, controls, safety, and grid-forming behavior.
• Develop BESS architecture, including pack-to-MV-transformer grouping, string composition, and medium-voltage collection topology.
• Determine sizing requirements based on compute duty cycles, step loads, and training-job ramps.
• Establish inverter control strategy, including grid-forming versus grid-following, droop, and virtual inertia.
• Create the plant controller and EMS functional specification for dispatch, state-of-charge management, and peak shaving.
• Develop the fire and life-safety case, adhering to UL 9540 and 9540A standards.
• Manage the OEM relationship, including technical requirements, factory testing, and performance guarantees.
• Direct various teams, including Design, Commissioning, Ops/Build, Network, Civil, and Program Manager.

Basic Qualifications:

• Bachelor's degree in electrical engineering, computer engineering, physics, or another engineering discipline.
• 8+ years of experience in power systems engineering.
• 4+ years of experience directly related to utility-scale or large commercial and industrial battery energy storage.

Preferred Skills and Experiences:

• Experience sizing storage against real duty cycles.
• Knowledge of NFPA 855, UL 9540 and 9540A, IEEE 1547, and IEEE 2800.
• Utility-scale BESS fleet experience.
• Understanding of grid-forming inverter control.
• Experience with PSCAD or other EMT modeling.
• Professional Engineering license or intention to seek one.
• Experience building and leading an engineering team.

Additional Requirements:

• Ability to perform hands-on work in various environments.
• Willingness to work extended hours and weekends as needed.
• Ability to remain focused in hazardous environments while wearing PPE.
• Physical ability to lift up to 25 lbs. unassisted.
• Availability for 24/7 on-call support for emergencies.
• Valid driver's license.
• On-site work in Memphis, TN, with up to 25% travel for work-related activities.
