Data Center Facilities Engineer III

Oracle Oracle · Enterprise · WI

This role focuses on the engineering ownership of mechanical and HVAC systems for hyperscale data centers, ensuring reliability, efficiency, and performance. Responsibilities include defining architectures, resolving complex issues, developing fleet standards, and partnering on capacity planning and upgrades. The ideal candidate has extensive experience in mission-critical mechanical systems and a strong understanding of cooling system fundamentals.

What you'd actually do

  1. Define, review, and improve mechanical/HVAC architectures and designs for high-availability environments (e.g., chilled water, DX, airside, redundancy strategies).
  2. Provide Tier-3 technical escalation for complex issues, including RCA, corrective action development, and verification of sustained fixes.
  3. Develop and maintain fleet standards for cooling redundancy, controls integration, equipment selection (e.g., chillers), and energy performance.
  4. Partner on capacity planning, retrofits, and emerging initiatives (e.g., liquid cooling, efficiency projects), ensuring operability and maintainability.
  5. Lead or support vendor technical reviews, commissioning acceptance criteria, and operational handover requirements.
