Systems Engineer - Battery Storage

About xAI

xAI's mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge.

Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity.

We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company's mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important.

All engineers are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

About the Role

You will design, deploy, and optimize large-scale battery energy storage systems (BESS) that power xAI's AI training superclusters in Memphis. These systems, built on Tesla Megapack platforms, must deliver uninterrupted, high-density power at multi-megawatt scale while maintaining extreme reliability under variable AI workloads. You will own the end-to-end lifecyclefrom site planning and integration to real-time performance tuning and long-term degradation managementensuring the storage fleet exceeds 99.999% availability and maximizes round-trip efficiency.

Responsibilities

• Lead electrical, mechanical, and thermal integration of Megapack-based BESS with on-site substations, inverters, and AI compute loads.
• Develop control strategies and firmware logic for dynamic load balancing, peak shaving, and frequency regulation tailored to AI training power profiles.
• Perform capacity modeling, cycle-life forecasting, and degradation analysis using field telemetry and digital-twin simulations.
• Commission systems, validate nameplate performance, and implement predictive maintenance protocols to minimize downtime.
• Collaborate with Tesla Energy teams on custom firmware, hardware revisions, and supply-chain scaling for xAI-specific duty cycles.
• Ensure compliance with NEC, NFPA, IEEE 1547, and local grid interconnection requirements; author interconnection studies and reliability reports.
• Drive root-cause investigations for any energy anomalies and implement corrective actions across the fleet.
