**Summary:**
Meta's AI infrastructure is scaling faster than anything the data center industry has designed for. We need a Mechanical Engineer who can own the next generation of liquid cooling and thermal systems — from first concept through construction — at a scale no one else is building. You will serve as the design authority for novel systems, defining technical approaches where established standards may not yet exist.This is a small, expert team where your decisions directly shape what gets built. You'll set technical direction across hydronic and thermal systems, mentor engineers around you, and drive programs that deliver megawatts of compute capacity. Our current focus areas include:- Technical Roadmap — Charting the path for next-generation mechanical systems and emerging technologies- Programmatic Designs — Develop future data center designs- Owner Furnished Equipment — Develop, maintain, optimize and manage risk of critical mechanical equipment.- Design Localization — ...
