Submer enables organizations scaling AI to overcome the limits of traditional datacenters across power, compute density and efficiency.

We design and deliver scalable, high-density AI datacenter infrastructure built around industry-leading liquid cooling, supporting everything from early AI deployments to full‑scale production environments.

Acting as a full‑stack delivery partner, Submer provides advisory, design, build and IT integration through a single point of accountability, working with a deep ecosystem of technology specialists. This end‑to‑end approach accelerates time‑to‑AI while reducing operational cost, complexity and environmental impact.

The result is AI infrastructure that performs today, scales predictably and avoids the redesigns and inefficiencies slowing the market down.

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.

• 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 7 years of proven experience in mission‑critical electrical design, with demonstrable data center project delivery.
• 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 collaboration skills with multidisciplinary teams.
• Ability to work in fast‑paced, client‑facing environments with tight delivery timelines.
