Manager, HV Electrical Engineering

Do you want to work with high-caliber professionals in a dynamic and growing company? Are you entrepreneurial, hard-working, and collegial? Join us at SB Energy, a leading infrastructure company backed by Soft Bank Group and Ares Infrastructure, pairing cutting-edge innovation with best-in-class execution. Our mission is to deliver reliable and secure data center and power infrastructure to strengthen America's future.

Founded in 2019, SB Energy is a Soft Bank Group company headquartered in Redwood City, California. In 2026, Soft Bank Group and OpenAI announced a $1 billion investment to support SB Energy as their leading development and execution partner for data center campuses, while Ares Infrastructure continues its long-standing support of the company's growth. SB Energy develops, builds, owns, and operates some of the largest and most technically advanced energy and data center infrastructure projects in the United States.

Since its founding, the company has rapidly grown into a top-tier integrated platform with more than 3 gigawatts (GW) in operation and a multi-GW pipeline of energy and data center infrastructure nationwide.

SB Energy also leverages a strong culture of innovation to identify and integrate new technologies into its projects, including its AI-based digital platform, delivering energy infrastructure that is local, reliable, and matched to load. We are building the energy and infrastructure future—today.

Come join us in accelerating the energy and infrastructure transition!

As a member of the Engineering team, the HV Engineer / Sr. HV Engineer will own assigned HV/MV electrical engineering scope for large-scale AI data center projects, including HV substations, transmission lines, utility interconnections, MV distribution, protection and control, and onsite generation. The role will work closely with the HV Lead Engineer and project teams to deliver reliable, scalable, and cost-effective electrical systems, while addressing utility/ISO requirements, large AI load characteristics, gas generation, BESS/UPS, and grid integration from concept through commissioning.

• Own assigned HV/MV electrical engineering scope for hyperscale AI data centers, including utility interconnections, transmission lines, substations, MV distribution, transformers, switch gear, protection and control, SCADA, and telecommunications, working under the direction of the HV Lead Engineer.
• Take ownership of the electrical design and engineering deliverables for high-capacity data center campuses, including utility service, HV substations, MV distribution, transformers, backup generation, BESS/UPS, and electrical distribution to the data center load.
• Own the design and technical review of HV substations and utility interconnections, including substation one-lines, bus configurations, transformer sizing, breaker and switch gear selection, grounding, protection and control, metering, relay coordination, and SCADA/communications.
• Own the engineering design and review of MV electrical systems from the substation to the data center, including MV feeders, switch gear, transformers, distribution topology, sectionalization, redundancy, and equipment sizing for large AI loads.
• Take responsibility for assigned transmission-line and utility interconnection engineering, including HV line routing, conductor selection, thermal and short-circuit requirements, insulation coordination, clearances, and utility/ISO interconnection requirements.
• Develop and evaluate N+1, 2N, and other high-reliability electrical architectures for large AI data center loads, considering load growth, rapid load changes, scalability, and future campus expansion.
• Own the technical evaluation of utility and ISO/RTO requirements for large AI data center loads, including interconnection requirements, power quality, voltage/frequency performance, fault ride-through, ramp-rate/load-change requirements, reactive power, power factor, harmonics, flicker, protection, and system stability.
• Evaluate the impact of AI load profiles, rapid load changes, and large load blocks on the utility grid and coordinate with utilities, ISOs/RTOs, and system studies teams to develop appropriate mitigation strategies.
• Own assigned electrical engineering scope for the integration of gas-fired generation, emergency/standby generation, microgrids, BESS/UPS, and other onsite power sources supporting data center reliability and grid…
