DC Operations Manager - Critical Infrastructure

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.

Nebius is building next generation, high density AI infrastructure, and we are looking for a Data Center Operations Manager - Critical Infrastructure to own the performance, reliability, and operational excellence of our data center facilities.

This is acritical facilities leadership role, responsible forpower, cooling, and environmental systems that support GPUdriven workloads. You will ensure our sitesoperatewithmaximumuptime, efficiency, and safety, while also supportingcapacity expansion and infrastructure improvementsas we scale.

Unlike a pure construction role, this position is focused onsteady-state operations, incident management, andlongtermfacility performance, with involvement incommissioning and new site readinesswhere needed.

• Own daytoday operations of electrical and mechanical systems including UPS, generators, switch gear, PDUs, chillers, CRAH/CRAC units, and cooling infrastructure

• Ensure high availability and uptime of all critical systems supporting data center operations

• Lead incident response for facility related events, including root cause analysis and corrective actions

• Monitor system performance via BMS/DCIM and drive improvements in reliability and efficiency

• Oversee preventive and corrective maintenance programs for all facility systems

• Manage and hold accountable thirdpartyvendors and service providers

• Ensure all maintenance activities follow SOPs, EOPs, and MOPs

• Drive standardization and continuous improvement of operational procedures

• Partner with engineering and operations teams on capacity planning and infrastructure scaling

• Monitor and improve PUE and overall energy efficiency

• Identify and implement reliability and sustainability improvements across facilities

• Support high density environments, including air and liquid cooling strategies aligned with modern AI workloads

• Ensure compliance with local regulations, safety standards, and industry best practices

• Maintain strong adherence to
  HSE (Health, Safety, Environmental)standards

• Lead audits, inspections, and documentation for operational readiness

• Act as the primary point of contact for facility related regulatory interactions

• Support commissioning, testing, and handover of new or expanded infrastructure

• Participate in FAT/SAT and system validation for critical equipment

• Ensure smooth transition from construction to steady state operations

• Validate that systems are operationally ready with proper documentation and procedures

• Partner closely with:

• • Data Center Operations teams
  • Infrastructure & deployment engineers Network and hardware teams

• Act as the bridge between facilities and IT infrastructure , ensuring both layersoperateseamlessly (a key distinction in Nebiusenvironments)

• Support broader operational goals around scalability, reliability, and standardization

• 7-10+ years of experience in data center or mission critical facilities operations

• Stronghandsonknowledge of critical infrastructure systems :

• Electrical distribution (UPS, generators, switch gear)

• Cooling systems (chillers, HVAC, CRAH/CRAC, liquid cooling exposure preferred)

• Experienceoperatingin high availability environments with strict uptime requirements

• Proven experience managing vendors, maintenance programs, and incident response

• Familiarity with BMS/DCIM systems and operational monitoring

• Experience developing and enforcing SOPs, EOPs, and MOPs

• Strong understanding of safety, compliance, and regulatory requirements

• Experience in hyperscale, colocation, or AI/GPUdriven data centers

• Exposure to high-density environments and…
