• Oversee and support systems including:
  • Chiller plants and chilled water systems
  • Evaporative (future) and DX cooling systems
  • Cooling towers (future) and heat rejection systems
  • CRAH/CRAC units and Fan Wall air distribution
  • Water distribution and treatment systems
  • Fire suppression and life safety systems
• Perform or oversee hands‑on troubleshooting, repair, retrofit, and maintenance of mechanical equipment
• Analyze system performance and operating data to identify inefficiencies and optimization opportunities

• Develop, review, and approve SOPs, MOPs, and EOPs for mechanical systems
• Contribute to and support site mechanical safety programs, including risk mitigation for personnel and critical systems
• Plan and approve work procedures for maintenance, troubleshooting, and retrofit activities
• Lead or participate in incident response and root cause analysis (RCA) for mechanical failures
• Ensure compliance with ASHRAE standards, local codes, and safety requirements

• Provide oversight from basis of design (BOD) through commissioning and operations
• Review mechanical system designs, equipment selections, and sequences of operation
• Provide QA/QC oversight of construction and retrofit activities
• Oversee system configurations and component upgrades, ensuring compliance with change management processes
• Participate in commissioning, testing, and factory witness activities
• Validate system performance for redundancy, failover, and thermal stability

• Provide feedback on global mechanical maintenance strategies and system design improvements
• Drive improvements in cooling efficiency, water usage, and system resilience
• Optimize system performance to support energy efficiency (PUE/WUE targets)
• Support development of scalable, repeatable hyperscale cooling system designs
• Support long‑term planning for capacity, retrofits, and emerging cooling technologies

• Collaborate across electrical, controls, and operations teams
• Interface with OEMs, vendors, contractors, and service providers
• Manage vendor relationships for maintenance, upgrades, and retrofit work
• Provide training to Critical Facility Operators and cross‑functional teams on mechanical systems and procedures

• 10+ years of relevant mechanical industry experience or trade experience
• Bachelor’s degree or trade certification in a related field (or equivalent experience)
• Strong expertise in:
  • HVAC and cooling systems in critical environments
  • Chilled water systems and refrigeration cycles
  • Psychrometrics and thermal performance
• Experience supporting maintenance, troubleshooting, testing, and/or construction of mechanical systems
• Working knowledge of electrical, controls, and fire/life safety systems
• Ability to interpret:
  • P&IDs
  • Mechanical drawings and specifications
  • Equipment shop drawings

• Experience in hyperscale or colocation data center environments
• Familiarity with ASHRAE standards and data center cooling guidelines
• Trade certification or state HVAC/mechanical license
• Experience with commissioning and integrated systems testing (IST)
• Background with OEMs, contractors, or field service engineering
• Experience with energy modeling, CFD, or system optimization tools
• Professional Engineer (PE) license

• Deep expertise in mechanical systems and thermal management
• Strong troubleshooting capability in live, mission‑critical environments
• Ability to operate across operations, construction, and design phases
• Strong cross‑functional communication across engineering and operations teams
• High attention to detail in system reliability,…
