Data Center Electrical Engineer Position Overview The Data Center Electrical Engineer is responsible for implementing, maintaining, and optimizing electrical systems and critical power infrastructure within mission-critical data center environments. This role ensures maximum uptime, reliability, and efficiency of power distribution systems while supporting the continuous operation of IT equipment and maintaining compliance with industry standards.
Key Responsibilities
Critical Power Systems Responsible for operations and maintenance of equipments and electrical infrastructure within data center. Support retrofits including medium voltage systems, transformers, switchgear, and power distribution. Develop electrical single-line diagrams, riser diagrams, panel schedules, and equipment layouts. Identify and report SPOFs within redundant power architectures (N, N+1, 2N) to meet Tier II, III, or IV certification requirements. Calculate load requirements, power densities, and capacity planning for current and future IT infrastructure needs. Power Distribution and UPS Management Oversee design and operation of uninterruptible power supply (UPS) systems including configuration, sizing, and redundancy schemes. Manage power distribution units (PDUs), remote power panels (RPPs), and branch circuit distribution. Implement power monitoring systems and DCIM platforms for real-time visibility into power consumption and capacity. Optimize power distribution efficiency and reduce energy losses throughout the electrical infrastructure. Generator and Backup Power Systems Operate and maintain backup generator systems including fuel systems, automatic transfer switches (ATS), and paralleling switchgear. Conduct load bank testing, generator commissioning, and regular preventive maintenance activities. Ensure seamless failover capabilities and validate backup power runtime calculations. Manage generator fuel supply contracts and emergency fuel delivery protocols. Operations and Maintenance Perform routine inspections, testing, and preventive maintenance on electrical equipment including switchgear, transformers, UPS systems, and distribution panels. Troubleshoot electrical faults, power quality issues, and equipment failures with minimal downtime impact. Coordinate maintenance windows and implement change management procedures for electrical system modifications. Monitor power quality metrics including voltage, frequency, harmonics, and power factor. Capacity Planning and Analytics Analyze power consumption trends and forecast future capacity requirements. Develop capacity models and utilization reports for executive leadership and client stakeholders. Identify stranded capacity and optimization opportunities to maximize infrastructure efficiency. Plan electrical infrastructure upgrades to support data center growth and evolving technology requirements. Project Engineering and Implementation Lead electrical engineering aspects of data center projects from design through commissioning. Coordinate with MEP contractors, equipment vendors, and internal teams to ensure successful project delivery. Review shop drawings, submittals, and equipment specifications for compliance with design requirements. Conduct site inspections during construction and verify installation quality and code compliance. Compliance and Documentation Ensure compliance with NEC, NFPA, IEEE, and local
