Meta is seeking a Mechanical Engineer experienced in the design and construction of Critical Facilities to become a part of our onsite Data Center Design Engineering team. Our data centers are the foundation upon which our software operates. Building and operating reliable and efficient data centers is essential to support the growth of Meta. The Design Engineering team collaborates with all key stakeholders to ensure engineering and design of our data centers incorporate considerations from micro-levels (servers and IT equipment design requirements) to macro-levels (mechanical cooling and power distribution options) to enable maximum efficiency and reliability of our compute infrastructure. As an integral part of the onsite team, you will support the design and onsite construction administration as a Design Owner Representative, Mechanical Design Engineer and subject matter expert. The role requires collaboration with multiple internal partner teams such as Construction, Quality, Safety, and Facility Operations, as well as external partners such as engineering consultants, general contractors, and regulatory agencies to deliver data center capacity safely, on time, within budget, and of high quality. This position is full-time, on project site, requiring engagement with stakeholders and providing directional guidance aligned with the pace of dynamic fast-tracked construction.
