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.
The Head of Data Center Design owns the overall technical design and architecture of the company's data centers, from initial site feasibility through approved engineering drawings. This role defines the technical vision — modular POD architecture, cooling strategy (including DLC), power topology, and reliability targets — and ensures that every design decision, from equipment selection to construction execution, stays aligned with that vision and meets company requirements. This is a hands-on technical authority role — the person must personally own decisions on power, cooling/DLC, and overall critical-infrastructure architecture, not just manage the design process.
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)
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
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)
