We are hiring a Head of DC Infrastructure 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. This role requires regular business trips to the construction site in Poland (full relocation is not required).
The Head of DC Infrastructure builds and leads the on-site engineering team responsible for the MEP systems (cooling, power, UPS, generators) that keep the data center running. This role owns day-to-day reliability of the facility's physical infrastructure post-handover — from preventive maintenance and incident response to commissioning support for new capacity expansions — ensuring MEP systems perform to design intent throughout the facility's operational life.
