System Engineer - Interconnect

The Accelerator Reference Design Team is looking for a System Engineer to design, implement, and maintain hardware designs for custom AI hardware interconnects. The ARD team is working on the design and implementation of hardware modules for Meta's custom AI accelerators. Meta is developing one of the world's highest performant AI/HPC clusters using custom-designed AI accelerators. In this role, you will have a unique opportunity to shape the future AI/HPC of Meta by specifying technical requirements for custom interconnects, driving specifications and designs of those interconnects, and steering the industry and ecosystem partners. The ideal candidate will operate in a highly multi-tasked, fast-paced and very cross-functional engineering environment. They will solve complex problems in high-performance AI that span across silicon, hardware, and software. They will also work directly in hardware design and protocol development for high-performance interconnects. A successful candidate will be a HW System and platform builder, work on rack scale solutions, individual servers, and custom ASICs. The candidate will also be fluent in state of the art high-performance interconnects. The position is for a lead developer and architect, debugging complex issues, working in broad and ambiguous problems, and delivering hardware systems at-scale. The candidate will work closely with internal customers and partners who are on the front-line of developing Meta's custom ASICs for AI. The Accelerator Reference Design Team designs, builds, brings-up, tests and integrates hardware systems that power Meta's custom AI silicon platforms, deployed in data centers worldwide. This is a rare opportunity to join our team and help us build some of the world's most open and efficient AI platforms.
