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 experience

- Proficiency in at least one modern programming language (e.g., Rust, C++, Java, Go)

- Experience building and operating distributed systems or backend services

- Solid grasp of CS fundamentals: data structures, algorithms, concurrency

Preferred 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 language

- Experience reasoning about consistency, coordination, or state machines in distributed systems

Who 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. If you like working hard, having fun, and making history - talk to us.

Who are we looking for? Smart, talented engineers who like hard problems. Networking background not required - we'll teach you. Come work hard, have fun, and make history with us.

Basic qualifications
