# Software Development Engineer II - AWS Networking Applications, SIDR

What do we do here? Amazon Web Services runs one of the largest networks in the world. Our organization designed a new routing protocol built for the demands of modern workloads, and our team built the control plane that implements it - governing how traffic moves across the fabrics of the Amazon data center network, reacting to both static topology and real-time state at a scale few systems operate at. Why now? Our control plane is expanding to cover more of AWS's network, and we're growing the team to match. We're looking for a software engineer who wants to go deep on large-scale distributed systems, hyperscale data center networks, SDN, and global software deployment. What you'll do? - Design and build the stateful control-plane software that applies intended network state across thousands of devices and guarantees they converge correctly and safely - including failure handling and rollback. - Own features end-to-end: requirements, design, implementation, code review, worldwide deployment, and operations. - Work with partner teams and customers to bring new algorithms and capabilities into production at scale. Basic Qualifications - 3+ years of professional software development
