Full Time / Permanent About Submer At Submer, we are redefining how data centers are built, integrated, and operated, with sustainability, efficiency, and innovation at the core. Our technology is designed to reduce environmental impact while improving performance and efficiency. We are a purpose-driven company with a passion for innovation and a growing global presence.

What impact you will have 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.

What you’ll do Electrical System Design & Engineering

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.

Power Distribution & Analysis

Perform load flow, short‑circuit, selectivity, and reliability studies using industry‑standard tools.

Specify and validate switchgear, transformers, busbar systems, protective devices, and cabling for high‑current distribution.

Evaluate redundancy schemes (N, N+1, 2N) and contribute to Tier certification requirements.

Commissioning & Delivery

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.

Compliance & Documentation

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.

Collaboration & Expertise

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).

What you’ll need

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.

Our job titles may span more than one job level. The actual base pay is dependent on a number of factors, such as transferable skills, work experience, business needs and market demands.

What we offer

Attractive compensation package reflecting your expertise and experience.

A great work environment characterised by friendliness, international diversity, flexibility, and a hybrid‑friendly approach.

You’ll be part of a fast‑growing scale‑up with a mission to make a positive impact, offering an exciting career evolution.
