You will be joining the team that is responsible for the end-to-end health (performance and reliability) of Meta’s backbone networks. You will build tools and use automation to efficiently scale how we mitigate real-time impact to the network, identify and investigate long-term trends into performance and risks in our backbone, and drive innovative solutions to monitor and improve Meta’s current and future backbone network products. Our backbones continue to rapidly expand globally, driven most recently through the network demands that our AGI journey brings. We support both our "Classic Backbone", that transports traffic destined to people using Meta’s products, and our "Express Backbone", that handles machine to machine traffic between our Data Centers. Engineers that typically thrive in this role are hybrid software and network engineers who are curious about how systems work, how they fail, and how we can increase their reliability. You have the opportunity to dig into interesting challenges in the networking and software domains, at a scale that offers new challenges on a daily basis.
