Head of Data Center Design

About the Position

We are hiring a Head of Data Center Design for our client - a company building a large-scale AI data center (with a planned capacity of 300 MW) in Poland, on a site currently undergoing active reconstruction into modern technological infrastructure. The first phase, with a capacity of 50 MW, is planned to go live this year.

Responsibilities

• Own the overall technical design and architecture of the data centers
• Define and maintain the Basis of Design: modular POD architecture, cooling strategy, power topology, fire suppression, networking
• Set design standards for IT deployment (rack layout, containerization, CDU placement)
• Lead design reviews and approve engineering drawings across disciplines (electrical, mechanical, structural, fire, networking)
• Own PUE, capacity, and reliability targets at the design stage
• Coordinate with equipment and technology partners on specs and integration requirements
• Work with implementation teams to ensure construction execution matches approved design intent
• Evaluate and approve design changes for technical impact (cooling, power, capacity, redundancy)
• Lead site selection technical criteria and feasibility studies (power availability, grid connection, cooling options)

Requirements

• 5+ years of experience in hyperscale/modern data center design, with direct, current or recent ownership of multidisciplinary DC design across mechanical, cooling/DLC, and high-density GPU infrastructure - 3+ years in a design leadership role
• Demonstrated ownership of Basis of Design documentation for large-scale, modern data center facilities
• Strong hands-on technical expertise in power topology and cooling strategy, including DLC - this must be personal technical authority, not delegated/coordinated through others
• Experience with high-density GPU/HPC compute environments and modular/POD-based deployment architectures
• Track record of leading multidisciplinary design reviews and approving engineering drawings across trades
• English proficiency sufficient for international technical documentation and stakeholder communication

Nice to Have

• Tier III/IV certification (Uptime Institute), or direct experience with certification processes
• Experience with NVIDIA GB200/GB300 or equivalent high-density GPU cluster infrastructure
• Background spanning both design and construction execution phases
• Experience with EU regulatory frameworks for power, environmental, and building compliance
• Fire suppression and structural loading design experience (beyond coordination level)

We Offer

• Full-time position
• Remote work location
