About Submer 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.
What Impact You Will Have We are seeking a Data Center MEP Design Engineer to lead the design, implementation, and optimization of end-to-end MEP systems - electrical, mechanical, and fire protection - in high-density environments. The objective is to ensure a safe, reliable, and scalable power and cooling infrastructure: from substation/transformer systems, MV/LV distribution, busbars and rack PDUs, to precision cooling, chilled-water pipe loops, CDUs, and liquid-cooling solutions such as TCS; as well as fire detection and suppression, and integration with BMS/EMS. The ideal candidate brings a strong background in mission-critical MEP infrastructure, optimizes metrics such as PUE/WUE, and thrives in fast-paced, multidisciplinary environments, supporting mission-critical workloads and next-generation computing platforms.
What You’ll Do Leadership & Scope
MEP Design, Integration & Delivery (Electrical/Mechanical/Fire Protection/Controls)
Performance Optimization & Reliability
Compliance & Documentation
OEM Collaboration & Commercial Support
What You’ll Need
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.
