Software Engineer - Traffic Capacity & Performance

Job description

Meta's edge network carries traffic in two directions: content out to billions of people from edge sites and caches inside internet service providers, and Meta's own services and AI agents reaching sites across the internet. The Traffic Capacity & Performance team decides how much capacity Meta builds for both, and where. We size it to keep serving through failures and demand spikes, drain sites at peak on purpose to find weak spots before a real outage does, and have apps and services ask for less when capacity runs low.
