Meta's datacenter footprint is constantly growing to adapt to the vast amount of new services we provide to people. This results in a dramatic scaling challenge that our engineers have to deal with on a daily basis. Not only do we need to build and evolve the physical infrastructure that connects myriads of servers together, but also ensure that the network is running smoothly and meets strict performance goals. The utilization of our own switch operating system (FBOSS) and our own network devices have propelled us into a new era of unprecedented opportunities to re-think traditional networking and rapidly innovate new solutions for traditional hyperscale and emerging AI data center networks. Meta's datacenter network engineering team is actively looking for people with passion to solve difficult problems and innovate at a fast pace. Data Center networking at Meta is a multi-faceted discipline and covers all layers, starting from physical (fiber and optics), actively using distributed routing protocols such as BGP and topping with our own software stack running on our network devices. For this role, we are looking for a Network Engineer with solid experience in network infrastructure and fiber connectivity solutions, including the design and deployment of data center infrastructure, ISP and OSP design, and optical technologies. Reach out to us if you are eager to innovate and contribute to our mission.
