What I'm looking for

I’m looking for a critical facilities/data center role where I can lead 24/7 power incident response, drive proactive PM using EPMS trends, and own generator/UPS operations with clear SLAs, safety-first standards, and opportunities to scale resilient infrastructure.

I’m a critical facilities electrical engineer with 3+ years operating multi-MW Tier III data centers across enterprise and colocation environments on 24/7 rotating 12-hour shifts. I thrive in high-stakes uptime environments where safe, repeatable processes and fast, accurate troubleshooting make the difference.

In my current role, I operate and maintain LV/MV switchgear, Vertiv/Eaton UPS systems, PDUs, ATS/STS units, and CAT/Cummins diesel generators for 500+ cabinets. I lead power system incident response for UPS transfer events, breaker trips, and voltage fluctuations—diagnosing root causes, coordinating vendor escalation, and restoring normal operations within SLA targets with zero load impact.

I’m equally focused on prevention: I participate in annual generator load bank testing and ATS transfer drills, and I use EcoStruxure EPMS trend analysis to identify repeat alarm patterns and reduce reactive incidents. Across roles, I’ve delivered zero safety incidents and full SLA compliance while executing PM/corrective maintenance, work order management in ServiceNow, and disciplined change management using MOPs and SOPs.
