Mechanical Engineer,Data Center Design Engineering Job San Francisco area,California USA,Engineering

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 — Lead the implementation of the programmatic designs for site‑specific conditions and support construction administration for self‑build and leases

Required Skills

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, Dry coolers, 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 & Controls Engineering teams to achieve holistic product designs optimized for cost, construction speed, operational efficiency, and long‑term flexibility

Collaborate with cross‑functional teams on prefabricated (DFSMA) solutions and modular component offerings (Building Block strategy) to be embedded into new design products

Partner with Energy & Water Modeling teams to evaluate environmental impacts, WUE optimization, and sustainability targets

Collaborate with Controls Engineering to ensure integrated mechanical control strategies and system‑level optimization

Collaborate with Hardware engineering to align rack‑level thermal and mechanical requirements (power density, coolant flow/pressure, temperature limits) with facility mechanical system design

Manage and hold EoR teams accountable on deliverables and performance

Prepare RFPs, analyze award recommendations, manage contracts, review change orders, VE proposals, shop drawings, submittals, RFIs

Participate in factory tests, onsite testing, commissioning, quality checks throughout project lifecycle

Balance short‑term delivery priorities while tracking industry standards and emerging trends to drive long‑term strategy with the Engineering Tech Strategy team

Perform research and develop analysis on new technologies, alternate materials, and liquid enablement solutions — building models of cost and environmental impact

Support R&D initiatives and pilot programs for next‑generation mechanical systems through the Research Lab

Evaluate and advance reliability/availability engineering practices to reduce downtime risk and improve system readiness

Drive design‑to‑break‑ground program schedules while working closely with design and construction teams to ensure milestones and completion dates are on track

Lead and oversee change management of applicable systems and drive towards resolution

Represent Meta's interests as Owner's Rep on self‑performed and leased facility projects

Partner with Site Selection on assigned site due diligence and master planning projects

Work with design engineers and field teams on new design types so they can correctly apply them to specific projects

Support operations on knowledge sharing, handover and…
