Data Center UPS SME

About the position

Applied Digital is seeking a highly skilled Data Center UPS – Operational Subject Matter Expert (SME) to oversee and optimize the performance, reliability, and efficiency of our data center UPS infrastructure. This role provides deep technical expertise in UPS technologies (e.g., online double-conversion, line-interactive, standby, modular, battery-backed), power quality, battery management, and integration with generators, switchgear, and critical loads. The SME supports design, installation, commissioning, preventive/corrective maintenance, troubleshooting, training, and continuous improvement to minimize downtime and ensure compliance in high-availability environments like data centers, hospitals, telecom, industrial plants, and financial institutions.

Responsibilities
• Act as the go-to technical expert for all UPS-related matters, including system architecture, sizing, redundancy (e.g., N+1, 2N), runtime calculations, and fault analysis.
• Lead or support preventive maintenance, corrective repairs, battery testing/replacement, firmware updates, and major component replacements (e.g., rectifiers, inverters, static switches).
• Troubleshoot complex UPS failures, power quality issues (harmonics, transients, voltage sags), and integration problems with downstream equipment.
• Develop, review, and update technical documentation, standard operating procedures (SOPs), maintenance protocols, and training materials.
• Deliver hands-on training and certification programs for technicians, engineers, and operations staff on UPS operation, safety, and best practices.
• Perform root cause analysis (RCA) on incidents, recommend improvements, and contribute to reliability enhancements (e.g., predictive maintenance using monitoring software).
• Ensure compliance with industry standards and regulations (e.g., IEEE, NFPA 70, UL 1778, IEC 62040, OSHA, local electrical codes).
• Collaborate with cross-functional teams (e.g., electrical engineers, data center ops, vendors, procurement) on new UPS deployments, upgrades, capacity planning, and vendor evaluations.
• Analyze system performance data, KPIs (e.g., MTBF, availability, efficiency), and monitoring tools (e.g., SNMP, BMS integration) to drive optimizations.
• Provide emergency on-call support for critical UPS failures and participate in disaster recovery planning.

Requirements
• Experience: 5–7+ years of hands-on experience with uninterruptible power supply systems, including installation, service, and advanced troubleshooting in critical power environments.
• Education: Bachelor's degree in Electrical Engineering, Power Systems, Electronics, or related equivalent field experience preferred.
• In-depth expertise in UPS topologies, battery technologies (VRLA, lithium-ion, wet cell), power electronics, and paralleling/redundancy configurations.
• Strong understanding of electrical systems, power distribution, generators, ATS, and harmonics mitigation.
• Proficiency with UPS diagnostic tools, multimeters, oscilloscopes, thermal imaging, battery impedance testers, and monitoring software.
• Excellent problem-solving, analytical, and communication skills for technical reporting and stakeholder interaction.
• Ability to read/interpret electrical schematics, one-line diagrams, and OEM manuals.

Nice-to-haves
• Certifications: Preferred – Manufacturer-specific (e.g., Schneider APC, Eaton, Vertiv/Liebert, CyberPower); relevant industry certs like Certified Data Centre Professional (CDCP), NFPA 70E (electrical safety), or battery/UPS-specific training.
