Infrastructure Reliability Engineer

THE COMPANY:

STACK INFRASTRUCTURE (STACK) provides digital infrastructure to scale the world’s most innovative companies. We are an award-winning industry leader in building, owning, and operating highly efficient, cost-effective wholesale, colocation, and cloud data centers. Each of our national facilities meets or exceeds the highest industry standards in all operational categories of availability, security, connectivity, and physical resilience.

STACK offers the scale and geographic reach that rapidly growing hyperscale and enterprise companies need. The world runs on data. Data runs on STACK.

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.

Responsibilities include but are not limited to:

• Lead deep-dive investigations and RCAs for electrical infrastructure failures, including UPS systems, switch gear, 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

• Location:
  
  Manassas or Sterling, VA, Portland, OR, Chicago (CHI), or Dallas-Fort Worth (DFW)

• Benefits:
  Healthcare, Dental Care, Vision Insurance, Life Insurance, Paid Time Off, Paid Leave Programs

• Travel: 25% domestically

• Must be eligible to work in the United States

• Must pass a comprehensive background screening

• 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, switch gear, 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)
