SeniorLead

About the role

  • The Reliability Engineer is accountable for facility infrastructure reliability across mission critical data center systems (power, cooling, controls).
  • You will design, implement, and continuously improve asset strategies and work management processes to achieve uptime, safety, and cost objectives.
  • Core work includes reliability analytics, PM optimization, MOP/SOP governance, change management, root cause analysis (RCA), and program execution for critical spares, condition monitoring, and lifecycle asset management.
  • Develop and maintain equipment strategies (criticality, failure modes, maintenance prescriptions) for power and cooling systems.
  • Own PM quality and audit activities; eliminate ineffective tasks and deploy optimized prescriptions.
  • Author, review, and govern SOPs/MOPs/EOPs and change packages; ensure adherence through training and approvals.
  • Partner with site teams to maintain CMMS schedules and O&M plans; lead reliability investigations and corrective actions.
  • Implement oil/coolant analysis, thermography, vibration, and battery monitoring; trend data to preempt failures.
  • Establish and maintain critical spares lists and stocking strategies; track gaps and remedial actions.
  • Support lifecycle asset management processes to guide replacements and capital planning.
  • Lead post incident RCAs and FMEA; publish learnings and update procedures.
  • Collaborate with CE leaders to uphold operator certification and training standards; mentor technicians on reliability methods.

Requirements

  • 7 years in reliability, maintenance engineering, or facilities engineering within mission critical environments.
  • Expertise with RCM, FMEA, RCA, and maintenance optimization.
  • Familiarity with UPS, generators, switchgear, chillers, cooling towers, CRAH/CRAC, and BMS/EPMS.
  • Experience governing SOP/MOP/EOP, CMMS scheduling, and change management.
  • Ability to analyze condition monitoring data and turn findings into actions.
  • Proficiency in data analysis and visualization tools (Excel, Power BI, or similar) to mine CMMS, condition-monitoring, and operational data for trends, failure patterns, and predictive insights.
  • Ability to apply statistical methods or reliability modeling to support decision-making.
  • Strong communication skills; able to lead investigations and drive consensus.
Benefits
  • Support 24×7 operations
  • Occasional on call rotation and night/weekend work
  • Ability to work in mechanical/electrical rooms around energized systems (following LOTO and NFPA 70E)
  • Travel to supported sites (~25 %)
