USA, WA, Seattle - 143,700.00 - 194,400.00 USD annually
Amazon's network is one of the largest in the world, and we are looking for a Software Development Engineer II to help build the intelligent controllers that decide how traffic moves across it. In this role you will tackle optimization and distributed-systems problems at regional scale, designing and delivering software that makes our network faster, more reliable, and more efficient. You will work across the full software development lifecycle, from defining requirements through design, implementation, testing, deployment, and operations. If you enjoy translating hard technical problems into clean, well-tested code and want your work to have visible, global impact, we want to hear from you.

Key job responsibilities
- Design and build components of intelligent network controllers, working with senior and principal engineers to align on system architecture and tradeoffs around scalability, performance, and security.
- Write high-quality, maintainable, and well-documented code across major portions of the team's systems, ensuring it can be extended by engineers who are not yet familiar with the codebase.
- Participate actively in operational support for the controllers, identifying root causes of issues and driving permanent fixes while continuously improving the team's operational processes.
- Mentor other engineers through code reviews and design discussions, raising the overall quality bar and helping teammates grow their skills.
- Evaluate new tools, approaches, and generative artificial intelligence capabilities to improve productivity, code quality, and the algorithms that power traffic optimization.

A day in the life
You might start by reviewing a design proposal from a teammate, offering feedback that sharpens the approach before code is written. Later you could be prototyping a new optimization algorithm alongside a scientist, then writing the distributed service that puts it into production. When an operational issue surfaces, you will dig into metrics with network engineers to find the root cause and ship a permanent fix. Throughout the day you will collaborate with a cross-disciplinary group of software engineers, scientists, and network engineers who all contribute to how traffic flows across Amazon's network.

About the team
Our team builds the intelligent traffic-engineering systems that shape how data moves across Amazon's global network. We are a cross-disciplinary group of software engineers, scientists, and network engineers, and we value an inclusive culture where every perspective strengthens our solutions. Right now we are investing in the next generation of intelligent traffic engineering, and this role will be central to that effort. If you want to solve optimization and large-scale distributed-systems problems that have real, measurable impact on network performance worldwide, this is the team to join.
