Critical Infrastructure Technician

About the role

You will guard the critical power path at a hyperscale datacenter where even seconds of power interruption translate into millions of dollars of impact and contractual penalties. Your systems (UPS modules, static transfer switches, downstream distribution to the rack) are the last line of defense for the IT load. You will monitor, maintain, and operate critical infrastructure with a discipline approaching aviation: every action planned in a method of procedure, every change controlled and reversible, every anomaly investigated to root cause rather than merely acknowledged.

What you will achieve

• Maintain 100 percent availability of the critical power path in your area through rigorous monitoring, preventive maintenance, and uncompromising change control on every intervention.
• Execute all critical work under method-of-procedure discipline with complete step-by-step documentation, achieving zero unplanned impacts to load across all your MOPs.
• Detect and resolve power quality anomalies (harmonic distortion, voltage transients, phase imbalance, neutral current) before they affect IT equipment, with trend data proving early intervention.
• Lead emergency response for power events in your area, executing contingency procedures calmly and correctly while communicating status clearly to the incident commander.
• Keep critical systems documentation (one-line diagrams, MOPs, emergency operating procedures, equipment databases) current, accurate, and drill-ready at all times.

What you will bring

Must-haves

• 2 to 5 years working with critical power systems: UPS, generators, static transfer switches, PDUs, or similar infrastructure.
• Deep respect for change control: you plan meticulously and never improvise on critical systems under any pressure.
• Strong electrical fundamentals and the ability to read and interpret power one-line diagrams and control schematics.
• Experience with BMS alarming, power monitoring systems, and trend analysis for predictive maintenance.
• Composure and decisiveness during power events, with clear communication under stress.
• High school diploma or equivalent; electrical certifications or apprenticeship valued.

Nice-to-haves

• Experience in Uptime Institute Tier III+ or concurrently maintainable facilities with their operational disciplines.
• Familiarity with lithium-ion UPS systems, battery management, and thermal runaway considerations.
• Background in commissioning or integrated systems testing (levels 4 and 5).
• Knowledge of EPMS platforms and power analytics.
