Job Description

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.

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 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, water use efficiency (WUE) optimization, and sustainability targets
* Collaborate with Controls Engineering to ensure that 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 for deliverables and performance
* Prepare RFPs, analyze award recommendations, manage contracts, review change orders, VE proposals, shop drawings, submittals, RFIs
* Participate in factory tests, on-site testing, commissioning, quality checks throughout the 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 that milestones and completion dates are on track
* Lead and oversee the change management of applicable systems and drive towards resolution
* Represent Meta's interests as the Owner's representative 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 that they can correctly apply them to specific projects
* Support operations on knowledge sharing, handover, and deployment planning to ensure smooth transitions from design to live operations
* Provide technical guidance on commissioning, startup sequencing, and system validation
* Travel up to 25% of the time to support project sites and construction activities

Qualifications
Experience communicating technical concepts in writing and presentations to both technical and non-technical audiences (e.g., design reviews, executive briefings, construction coordination meetings)
* Experience with all phases of design delivery (SD, DD, CD, CA)
* Bachelor of Science degree in Mechanical Engineering or equivalent practical experience
* Demonstrated expertise in liquid cooling systems, chiller plant design, and/or hydronic system designs
* 15+ years of experience in mechanical engineering for mission-critical facilities or data centers
* Experience leading large-scale mechanical design programs from concept through construction Experience with prefabricated/modular construction methodologies (DfSMA)
* Experience with operations and deployment handover for data center mechanical systems
* Hardware engineering thermal (HWE-Thermal) background — thermal design validation and product reliability
* Background in R&D or piloting new mechanical technologies in production environments
* Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
* Experience with acoustics/noise engineering and regulatory compliance for mechanical equipment
* Controls system fluency — understanding of BMS/EPMS integration and mechanical controls logic
* Deep expertise in availability and reliability engineering for critical infrastructure
* Familiarity with advanced tooling, simulation, or AI-driven design optimization
* Track record of mentoring engineers and building team capability
* Experience representing owner interests on large capital programs
* Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
* PE license (Mechanical)
* Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
* Experience with electrical and MEP integration, with the ability to work across disciplines
