Head of DC Infrastructure

About the Position

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).

Responsibilities

• Build and lead the on-site engineering team responsible for MEP systems (cooling, power, UPS, generators)
• Own day-to-day reliability and performance of all MEP systems at the site
• Develop and maintain SOPs/MOPs/EOPs for cooling and electrical operations, aligned with facility standards
• Lead incident response and root-cause analysis for MEP-related outages or failures
• Own the preventive maintenance program and schedules across cooling and electrical systems
• Coordinate maintenance windows and redundancy switching to minimize IT service impact
• Manage vendor/contractor relationships for MEP maintenance and warranty service, in coordination with other teams
• Support commissioning of new MEP infrastructure and expansions (FAT/SAT, handover from construction)
• Ensure compliance with safety protocols and manufacturer/regulatory requirements
• Manage on-call rotation and emergency response coverage for engineering staff

Requirements

• 7+ years of hands-on data center facilities/MEP engineering experience, with 3+ years in a leadership role already owning a full-scale DC Infrastructure/Operations function - this is a Head-level position, not a stepping stone into one
• Demonstrated experience operating and maintaining mechanical and electrical systems (cooling, UPS, generators, switchgear) specifically in a data center environment
• Hands-on experience developing SOPs/MOPs/EOPs for critical facility operations
• Proven track record leading incident response and root-cause analysis for MEP outages
• Experience managing preventive maintenance programs and vendor/contractor relationships
• Experience supporting or leading FAT/SAT and commissioning handover for MEP infrastructure
• Experience building and managing on-call/shift rotations for 24/7 facility coverage
• English proficiency sufficient for international vendor and technical communication
• Willingness to travel regularly to the construction/operations site in Poland

Nice to Have

• Experience with high-density liquid-cooled (DLC) infrastructure and CDU operations (traditional HVAC/air-cooling background is fully acceptable)
• Uptime Institute or EPI certification
• Experience managing MEP teams across multiple sites
• Background transitioning facilities from construction/commissioning into steady-state operations

We Offer

• Opportunity to lead a critical function in a cutting-edge AI data center
• Competitive compensation package
• Remote work options
• Professional growth and development opportunities
