Software Development Engineer II - AWS Networking Applications, SIDR

Software EngineerAmazon 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. 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 experienceProficiency in at least one modern programming language (e.g., Rust, C++, Java, Go)Experience building and operating distributed systems or backend servicesSolid grasp of CS fundamentals: data structures, algorithms, concurrencyPreferred Qualifications:Experience with large-scale, fault-tolerant systems and operational ownership (on-call, incident response)Exposure to Rust, or demonstrated ability to ramp quickly on a new languageExperience reasoning about consistency, coordination, or state machines in distributed systemsWho we are: a highly motivated team of software developers who thrive on hard distributed-systems problems and building at a scale few engineers get to work on.
