About The Position

Submer is seeking a Senior AI Data Center Electrical Engineer to lead the electrical power design, implementation, and optimization of high-performance computing (HPC) and AI data centers. The role focuses on reliable, scalable, and efficient power infrastructure for large-scale GPU-accelerated systems, including 100–300 MW facilities and modular data center deployments of 1–2 MW per unit that aggregate into 50–300 MW sites. The position calls for expertise in NVIDIA Grace Blackwell (GB300) and Vera Rubin (VR200) reference architectures.

The engineer will design and optimize medium- and low-voltage distribution systems; lead power architecture for NVIDIA Superpod and reference deployments; develop backup power and energy storage solutions; and architect modular data center systems. The role also includes power system studies, standards compliance, MEP integration, producing and explaining single-line diagrams, and supporting construction, commissioning, and operations. The engineer will evaluate emerging technologies, mentor junior engineers, and contribute to company standards and best practices.

The position offers an attractive compensation package, medical insurance, a 401(k) employee volunteer contribution plan, and a friendly, internationally diverse, flexible, hybrid-friendly work environment at a fast-growing scale-up. The company states that base pay depends on transferable skills, work experience, business needs, and market demands. Submer is an equal opportunity employer. The company cannot provide US work authorization for this position.

• Bachelor’s degree or higher in Electrical Engineering, Power Systems, or a related field.
• 10+ years of progressive electrical engineering experience in mission-critical facilities, including at least 5 years focused on large-scale data centers.
• Proven experience designing and deploying HPC/AI data centers at 100–300 MW scale.
• Hands-on experience with 1–2 MW modular data centers aggregated into 50–300 MW sites.
• Deep expertise in NVIDIA Grace Blackwell (GB300) and Vera Rubin (VR200) reference architectures, including power delivery, in-line BESS, transformers, switchgear, busways, power smoothing, and related MEP requirements.
• Strong knowledge of high-density power systems, including MV/LV switchgear, overhead busways, circuit breakers, PDUs, BESS, UPS, generators, power smoothing, and harmonic mitigation.
• Experience with power system analysis tools such as ETAP or SKM and with commissioning processes.
• Excellent problem-solving, communication, and leadership skills, with the ability to work in fast-paced, cross-functional environments.

Nice To Haves

• Professional Engineer (PE) license.
• Experience with liquid-cooled, high-power-density racks (100+ kW) and rack-scale systems such as NVIDIA NVL72/SuperPOD.
• Familiarity with Grid-to-Rack power distribution, MEP equipment in single-line power specifications, 13.8kV/34.5kV distribution to IT white spaces, 480V AC and/or 800V DC distribution, BESS integration, and renewable/grid-tied systems.
• Background in hyperscale operators, colocation providers, or AI infrastructure projects.
• Knowledge of data center standards such as Uptime Institute and TIA-942, and safety protocols such as NFPA 70E and OSHA.

Responsibilities

• Design, specify, and optimize medium- and low-voltage electrical distribution systems for hyperscale and modular HPC/AI data centers, including switchboards, overhead busways, circuit breakers, transformers, PDUs, RPPs, grounding, and protection systems.
• Lead power architecture for NVIDIA GB300 Grace Blackwell and VR200 Vera Rubin Superpod/reference deployments, including high-density rack power, liquid-cooling integration, power smoothing, and synchronous load management.
• Develop and implement BESS, UPS, generators, and backup power solutions to support uptime and grid stability.
• Architect 1–2 MW modular data center solutions that scale into larger HPC/AI sites, emphasizing rapid deployment, standardization, and interoperability.
• Perform power system studies, including short circuit, arc flash, coordination, load flow, harmonics, and grounding, and ensure compliance with applicable codes and standards.
• Collaborate with mechanical, structural, and IT teams on MEP integration, including 480V AC and 800V DC architectures, overhead busway distribution, and high-current delivery systems.
• Create and explain detailed single-line power-flow diagrams, provide specifications, and justify design decisions to technical and non-technical customers.
• Support construction, commissioning, and operations by reviewing drawings, specifications, and submittals; troubleshooting issues; and optimizing efficiency, capacity planning, and cost.
• Evaluate and integrate emerging technologies for power density, energy efficiency, and sustainability in AI factories.
• Mentor junior engineers and contribute to company standards and best practices for data center electrical infrastructure.

Benefits

• Attractive compensation package reflecting expertise and experience.
• Medical insurance plan.
• 401(k) employee volunteer contribution plan.
• Friendly, internationally diverse, flexible, hybrid-friendly work environment.
• Career evolution at a fast-growing scale-up with a mission to make a positive impact.
