Mechanical Engineer, Data Center Design 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: 1. Lead and/or assist on new data center product designs, integrating technological advancements while balancing cost, efficiency, time-to-delivery, and sustainability 2. 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 3. Drive the design and development of airside and hydronic systems including CDU, Valve Train, Fan Coils, Central Chiller Plants, Drycoolers, and Cooling Towers 4. 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 5. 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 6. Collaborate with cross-functional teams on prefabricated (DFSMA) solutions and modular component offerings (Building Block strategy) to be embedded into new design products 7. Partner with Energy & Water Modeling teams to evaluate environmental impacts, WUE optimization, and sustainability targets 8. Collaborate with Controls Engineering to ensure integrated mechanical control strategies and system-level optimization 9. Collaborate with Hardware engineering to align rack-level thermal and mechanical requirements (power density, coolant flow/pressure, temperature limits) with facility mechanical system design 10. Manage and hold EoR teams accountable on deliverables and performance 11. Prepare RFPs, analyze award recommendations, manage contracts, review change orders, VE proposals, shop drawings, submittals, RFIs 12. Participate in factory tests, onsite testing, commissioning, quality checks throughout project lifecycle 13. Balance short-term delivery priorities while tracking industry standards and emerging trends to drive long-term strategy with the Engineering Tech Strategy team 14. Perform research and develop analysis on new technologies, alternate materials, and liquid enablement solutions — building models of cost and environmental impact 15. Support R&D initiatives and pilot programs for next-generation mechanical systems through the Research Lab 16. Evaluate and advance reliability/availability engineering practices to reduce downtime risk and improve system readiness 17. Drive design-to-break-ground program schedules while working closely with design and construction teams to ensure milestones and completion dates are on track 18. Lead and oversee change management of applicable systems and drive towards resolution 19. Represent Meta's interests as Owner's Rep on self-performed and leased facility projects 20. Partner with Site Selection on assigned site due diligence and master planning projects 21. Work with design engineers and field teams on new design types so they can correctly apply them to specific projects 22. Support operations on knowledge sharing, handover and deployment planning to ensure smooth transitions from design to live operations 23. Provide technical guidance on commissioning, startup sequencing, and system validation 24. Able to travel up to 25% of the time **Minimum Qualifications:** Minimum Qualifications: 25. Experience communicating technical decisions in writing and in presentations to both technical and non-technical audiences (e.g., design reviews, executive briefings, RFI responses) 26. Experience leading large-scale mechanical design programs from concept through construction 27. 10+ years of experience in mechanical engineering for mission-critical facilities or data centers 28. Demonstrated expertise in liquid cooling systems, chiller plant design, and/or hydronic system design 29. Bachelor of Science degree in Mechanical Engineering or equivalent practical experience 30. Experience with all phases of design delivery (SD, DD, CD, and CA) **Preferred Qualifications:** Preferred Qualifications: 31. Track record of mentoring engineers and building team capability 32. Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies 33. PE license (Mechanical) 34. Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews) 35. Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements) 36. Experience representing Owners' interests on large capital programs 37. Experience with prefabricated/modular construction methodologies (DfSMA) 38. Electrical/MEP integration depth — ability to work across disciplines holistically 39. Hardware engineering thermal (HWE-Thermal) background — thermal design validation and product reliability 40. Experience with operations and deployment handover for data center mechanical systems 41. Controls system fluency — understanding of BMS/EPMS integration and mechanical controls logic 42. Background in R&D or piloting new mechanical technologies in production environments 43. Familiarity with advanced tooling, simulation, or AI-driven design optimization 44. Experience in availability and reliability engineering for critical infrastructure 45. Experience with acoustics/noise engineering and regulatory compliance for mechanical equipment **Public Compensation:** $173,000/year to $245,000/year + bonus + equity + benefits **Industry:** Internet **Equal Opportunity:** Meta is proud to be an Equal Employment Opportunity and Affirmative Action employer.
