The Network Infrastructure team is responsible for designing, building and operating one of the largest networks in the world. Networking is at the core of all Meta products and experiences, and we are looking for experienced Production Engineers who are interested in solving complex technical challenges in the Backbone or Datacenter Network domains. Production Network Engineers at Meta are hybrid software and network engineers who keep reliability and scalability in mind as they work on different parts of the lifecycle (designing, building, and operating our worldwide network). This role offers an opportunity to solve the scaling challenges of supporting billions of people using our family of apps; to cutting-edge challenges in AI workloads that power new Meta products. 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.
