The Role

The Data Center Site Manager owns end‑to‑end reliability, safety, capacity, and performance for one of our flagship U.S. sites. You’ll lead a high‑performing, multi‑disciplinary operations team and partner tightly with Design, Build, Network, Security, Capacity Planning, and the DC orgs to deliver world‑class availability and cost efficiency.

Your responsibilities will include:

• Own the site 24/7: deliver continuous availability across power, cooling, structured cabling, network, security, and DCIM—meeting or beating global SLAs.
• Build and lead the team: hire, mentor, and develop managers/technicians; run staffing models, shift coverage, and on‑call rotations that scale.
• Be the incident commander: lead major events end‑to‑end—triage, communications, executive briefings, RCA, and durable corrective actions.
• Drive reliability engineering: implement RCM, predictive maintenance, QA/QC, 5S, and Lean/continuous improvement to cut MTTR and raise MTBF.
• Deliver capacity on time: plan and execute expansions/retrofits; commission MEP systems with Design/Construction; achieve flawless change control (MOP/SOP/EOP).
• Scale tooling & automation: mature DCIM/BMS/EPMS, monitoring/alerting, work management (Jira/ServiceNow), knowledge base (Confluence), and light scripting/SQL for telemetry and workflow automation.
• Run a metrics‑first operation: publish dashboards and KPIs (availability, PUE, MTBF/MTTR, work compliance, safety) and use them to drive decisions.
• Partner across functions: work with Cloud/Compute, Network, Security, and Capacity Planning to optimize performance, cost, and resiliency across the fleet.
• Manage vendors & colos: own contracts, SLAs, and execution for rack deliveries, PDUs, fiber/copper, and lifecycle PMs; validate colo topology and compliance.
• Raise the safety bar: enforce a zero‑injury EHS culture; conduct drills/audits for life safety, physical security, and data protection.
• Forecast and budget: build data‑backed plans for power, spares, headcount, and projects; track OpEx/CapEx with rigor.

We expect you to have:

• Associate’s degree or trade certification in Electrical/Mechanical/Industrial Engineering (or equivalent experience).
• 10+ years in electrical/mechanical/HVAC/controls within industrial/commercial settings, 5+ years specifically in data center or mission‑critical facilities.
• Team leadership experience in 24/7 sites (managing leads/techs, vendors, and on‑call operations).
• Deep, hands‑on knowledge of UPS/generators/switchgear, chillers/CRAC/CRAH, fire detection/suppression, BMS/EPMS/DCIM, and structured cabling (copper & fiber).
• Proven strength in incident management, RCA/Corrective Actions, change management, and vendor/contract oversight.
• Data‑driven mindset with the ability to forecast resources and make analytics‑backed decisions (Excel; SQL/scripting a plus).
• Excellent written/verbal communication with comfort presenting to executives and guiding field teams during live events.
• Ability to travel up to ~30% and support after‑hours escalations when needed.

It would be an added bonus if you have:

• Bachelor’s degree in Electrical/Mechanical/Industrial Engineering, Engineering Management, or Reliability Engineering.
• Hyperscale/colo experience with reliability‑centered maintenance, predictive analytics, and Lean/Six Sigma practices.
• Familiarity with Linux fundamentals, network equipment installation/troubleshooting, and fiber optics testing.
• Experience with Jira, Confl
