About Nebius: Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure. Built by engineers, for engineers.

From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI. Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

The Role The Data Center Design Lead will partner with internal infrastructure, hardware, and operations teams, as well as external consultants, engineers, and construction firms, to deliver designs that support rapid deployment and long-term operational excellence.

Requirements

You will be responsible for both hands-on design oversight and technical leadership, serving as the final authority on data center design decisions.

into facility design specifications (power, cooling, network, and floor space). • Ensure designs optimize density, reliability, and efficiency while supporting rapid scalability. • Coordinate with mechanical, electrical, and plumbing (MEP) engineers and consultants to deliver detailed designs.

for high-density rack power, redundancy and UPS configurations. • Lead cooling design trade-offs (air, liquid, immersion) to meet GPU cluster needs. • Evaluate and integrate renewable energy and sustainability initiatives.

Network & Infrastructure Integration • Work closely with network and hardware teams to ensure physical layout supports cabling, interconnects, and future expansion. • Plan for modular design that enables incremental GPU cluster growth. , Uptime Institute Tier guidelines, local building codes).

• Incorporate safety, fire suppression, and physical security measures. • Define documentation and as-built standards for ongoing operations. Cross-Functional Collaboration • Coordinate with construction project managers and external contractors during build phases.

• Provide design oversight during commissioning and handover to operations. Continuous Improvement • Evaluate emerging GPU data center technologies and integrate innovative solutions. • Develop playbooks and design templates for repeatable, fast deployments.

• Benchmark efficiency (PUE, WUE) and reliability across sites to drive improvement.
