2. Manage power distribution and redundancy, including UPS, PDUs, backup power systems, and grid interconnects.
3. Energy storage solutions to support renewable energy integration.
4. Optimize PUE (Power Usage Effectiveness) and drive cost-efficient energy consumption.
5. Oversee waste heat recovery initiatives to support sustainability goals.
Networking & Physical Infrastructure:
1. Ensure high-bandwidth, low-latency networking to support multi-datacenter AI workloads.
2. Implement advanced DCIM (Datacenter Infrastructure Management) tools for real-time monitoring of power, cooling, and environmental conditions.
3. Predictive maintenance and automated issue detection.
Operational Reliability & Compliance:
1. Develop preventive maintenance schedules to maximize infrastructure reliability.
2. Implement automated monitoring and alerting systems for early detection of potential failures.
3. Ensure compliance with industry standards, including ISO 27001, SOC 2, TIA-942, and Uptime Institute Tier certifications.
4. Maintain disaster recovery and business continuity plans to ensure datacenter resilience.
5. Optimize CapEx and OpEx for datacenter construction, expansion, and operations.
6. Negotiate contracts with hardware suppliers, energy providers, and colocation partners to ensure cost-efficient AI infrastructure.
What you'll need
1. 10+ years of experience in datacenter infrastructure management, colocation operations, or enterprise IT facilities management.
