This position will play a vital role in ensuring the ongoing performance, resiliency, and evolution of infrastructure systems across STACK's portfolio. This role requires deep technical fluency in data center power and cooling systems, a forensic mindset for failure analysis, and a proactive approach to risk reduction. Responsibilities include but are not limited to: * Lead deep-dive investigations and RCAs for electrical infrastructure failures, including UPS systems, switchgear, breakers, relays, generators, grounding systems, STS behavior, VFD interactions, controls, and power quality disturbances * Evaluate electrical system performance under abnormal, fault, or degraded conditions (e.g., grounding faults, harmonics, transient events, protective coordination, voltage distortion, transfer events) to identify systemic vulnerabilities * Engage OEMs and vendors to challenge technical assumptions and advocate for long-term improvements * Support the evolution of maintenance standards and asset strategy for high-risk or complex systems (e.g., power distribution, cooling) * Collaborate with Workforce Development to enhance technical training for site teams based on lessons from event investigations * Contribute to availability reporting, event response improvement, and risk trend monitoring to ensure SLA commitments are met * Inform and influence the design review and turnover process by identifying gaps in infrastructure handoffs, system limitations, or commissioning practices * Develop system-level failure mode mitigation strategies that improve uptime performance and reduce repeat incidents * Partner with Operations, Engineering and Construction to review electrical design assumptions, protective schemes, equipment compatibility, and commissioning practices to identify long-term reliability risks prior to or following operational events ## Related Videos - [What Production Knows: Closing the Loop Between AI Agents and the Systems They Build](https://www.wearedevelopers.com/videos/100277-what-production-knows-closing-the-loop-between-ai-agents-and-the-systems-they-build) - [Is your backend a hodgepodge of queues, event stores and cron jobs?
