About The Position

STACK is looking for an Infrastructure Reliability Engineer with subject matter expertise in electrical systems who will act as a key member of STACK’s Critical Operations team. 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.

Requirements

5–8 years of experience in critical infrastructure environments (e.g., data centers, substations, power generation, or utility systems)
Strong technical fluency in mission-critical electrical systems, including power distribution architecture, UPS systems, generators, grounding methodologies, protective relays, switchgear, controls integration, and power quality analysis
Experience analyzing electrical failures through waveform data, event logs, relay coordination, commissioning findings, or forensic troubleshooting
Working knowledge of electrical system design intent versus operational field realities, including maintainability, equipment compatibility, and fault response
Hands-on experience with root cause analysis and reliability methodologies (e.g., FMEA, RCM)
Demonstrated ability to work across disciplines (Ops, Eng, Vendors, Construction) to resolve complex technical issues
Expertise with commissioning (Cx) and infrastructure design review processes
Ability to analyze performance data and translate findings into practical improvements
Bachelor's degree in Engineering or equivalent experience with high technical competency
Must be eligible to work in the United States
Must pass a comprehensive background screening

Nice To Haves

You are a strong communicator, you are persuasive and clear, blending analytics with experience in decision-making.
You do not get flustered easily. You can juggle multiple priorities while balancing urgent requests with shifting timelines and deliverables.

Responsibilities

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
