Data Center Facilities Engineer III

As a Facilities Technician - Mechanical, you will provide engineering ownership for the reliability, efficiency, and lifecycle performance of mission-critical mechanical and HVAC systems supporting hyperscale data centers. This role sets technical direction, resolves high-impact issues, and drives standards and upgrades that protect uptime and improve long-term performance. 

Key Responsibilities  

• Define, review, and improve mechanical/HVAC architectures and designs for high-availability environments (e.g., chilled water, DX, airside, redundancy strategies).  

• Provide Tier-3 technical escalation for complex issues, including RCA, corrective action development, and verification of sustained fixes.  

• Develop and maintain fleet standards for cooling redundancy, controls integration, equipment selection (e.g., chillers), and energy performance.  

• Partner on capacity planning, retrofits, and emerging initiatives (e.g., liquid cooling, efficiency projects), ensuring operability and maintainability.  

• Lead or support vendor technical reviews, commissioning acceptance criteria, and operational handover requirements.  

• Partner with procurement, facilities, and construction to improve total cost of ownership through standardization and performance-driven specifications.
