Mechanical Engineer, Data Center Design Engineering

Meta Meta · Big Tech · Menlo Park, CA +1

Mechanical Engineer for Meta's Data Center Design Engineering team, focusing on next-generation liquid cooling and thermal systems to support AI infrastructure scaling. The role involves owning design from concept to construction, setting technical direction, mentoring engineers, and driving programs for compute capacity. Responsibilities include leading product designs, owning mechanical systems strategies, developing design documentation, collaborating with cross-functional teams, and managing programs. Qualifications include extensive experience in mechanical engineering for mission-critical facilities, expertise in liquid cooling and hydronic systems, and a track record of mentoring. While the role supports AI infrastructure, it is not directly building AI models or systems.

What you'd actually do

  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

Skills

Required

  • Experience communicating technical decisions in writing and in presentations to both technical and non-technical audiences (e.g., design reviews, executive briefings, RFI responses)
  • Experience leading large-scale mechanical design programs from concept through construction
  • Demonstrated expertise in liquid cooling systems, chiller plant design, and/or hydronic system design
  • Bachelor of Science degree in Mechanical Engineering or equivalent practical experience
  • Experience with all phases of design delivery (SD, DD, CD, and CA)
  • Track record of mentoring engineers and building team capability

Nice to have

  • PE license (Mechanical)
  • Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
  • Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
  • Experience representing Owners' interests on large capital programs
  • Experience with prefabricated/modular construction methodologies (DfSMA)
  • Electrical/MEP integration depth — ability to work across disciplines holistically
  • Hardware engineering thermal (HWE-Thermal) background — thermal design validation and product reliability
  • Experience with operations and deployment handover for data center mechanical systems
  • Controls system fluency — understanding of BMS/EPMS integration
