Submer designs and delivers end-to-end AI datacenter infrastructure built around industry-leading liquid cooling. We help organizations scale AI beyond the limits of traditional datacenters by enabling higher density, greater efficiency and lower environmental impact – accelerating time-to-AI from first deployment to full production.

We are seeking a Senior Electrical Engineer to lead the design and delivery of electrical systems for high-density data centers, including both conventional and direct liquid cooling (DLC) facilities. This role is focused on ensuring safe, resilient, and scalable electrical infrastructure; from utility interface down to rack-level distribution, supporting mission-critical environments and next-generation compute platforms. The ideal candidate combines strong technical expertise with hands‑on project experience and thrives in multidisciplinary teams delivering complex data center projects.

• Lead a landmark AI data center project:
  Phase 1 of a 100 MW “AI factory” in Georgia, fast-track, hyperscale, high-density - not a traditional colocation or enterprise facility.
• Work at the forefront of AI infrastructure:
  Gain unique, marketable experience designing state‑of‑the‑art power, cooling, and compute systems.
• Fast‑paced, high‑impact environment:
  Contribute to a project that pushes the boundaries of scale, density, and next‑generation data center design.

• Develop end-to-end electrical designs for data centers (MV, LV, UPS, generators, busbars, PDUs, rack‑level distribution).
• Produce detailed schematics, one‑line diagrams, layout drawings, and technical specifications.
• Integrate electrical design with mechanical and IT systems, with a special focus on DLC requirements and interfaces.
• Lead design reviews and ensure compliance with project requirements, client standards, and industry best practices.

• Perform load flow, short‑circuit, selectivity, and reliability studies using industry‑standard tools.
• Specify and validate switch gear, transformers, busbar systems, protective devices, and cabling for high‑current distribution.
• Evaluate redundancy schemes (N, N+1, 2N) and contribute to Tier certification requirements.

• Support procurement, vendor evaluation, and technical submittal reviews.
• Oversee factory acceptance tests (FATs), site acceptance tests (SATs), commissioning, and handover activities.
• Troubleshoot electrical issues, drive root cause analysis, and implement corrective measures.

• Ensure all designs comply with NEC/IEC codes, local regulations, and global data center standards.
• Develop and maintain technical documentation, including specifications, test protocols, and O&M manuals.
• Contribute to risk assessments, method statements, and safety compliance plans.

• Work closely with clients, architects, mechanical engineers, and IT specialists to deliver integrated solutions.
• Provide subject matter expertise on DLC‑specific electrical design challenges (higher rack densities, liquid‑to‑liquid interfaces, safety protocols).

• Bachelor’s or Master’s degree in Electrical Engineering (or related field).
• Minimum of 8 years of proven experience in mission‑critical electrical design with a strong exposure to (at least 6 years) in large‑scale, high‑density, fast‑track data center project delivery.
• AI infrastructure experience is a plus.
• Strong knowledge of power distribution from MV/LV down to rack‑level (busbars, PDUs, server power delivery).
• Experience with direct liquid cooling (DLC) environments and high‑density compute facilities.
• Strong understanding of Tier certification requirements, electrical codes (NEC, IEC), and international standards.
• Excellent problem‑solving, analytical, and troubleshooting skills.
• Strong communication and…
