Mechanical Engineer, Data Center Design Engineering

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 large scale. You won't be reviewing someone else's design. You'll be the design authority for systems that do not have a playbook yet.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 land real 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 — Lead the implementation of the programmatic designs for site\-specific conditions and support construction administration for self\-build and leases. ### **Mechanical Engineer, Data Center Design Engineering Responsibilities:** * Lead and/or assist on new data center product designs, integrating technological advancements while balancing cost, efficiency, time\-to\-delivery, and sustainability * Own data center product mechanical systems strategies and infrastructure designs — including liquid cooling, chiller plant design, and heat rejection systems — from concept through construction administration * Drive the design and development of airside and hydronic systems including CDU, Valve Train, Fan Coils, Central Chiller Plants, Drycoolers, and Cooling Towers * Develop design documentation and drive design execution across all design and delivery phases (SD, DD, CD, CA) for self\-builds (greenfield), lease facilities and retrofit projects * Work closely with CSLA, Electrical, Connectivity and Controls Engineering teams to
