AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we're the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we're looking for talented people who want to help. You'll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You'll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And you'll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion. Amazon's network is a key differentiator for Amazon Web Services (AWS), enabling the global operation of thousands of applications on millions of servers worldwide. The AWS Networking team develops and operates the global network platform for all of Amazon, superseding a network that originally evolved using industry-standard technologies and designs. Our teams support all aspects of connectivity between Amazon and the outside world, as well as connectivity between Amazon's data centers and services. Internet Edge Services (IES) enables optimal connectivity for AWS customers via software. We build and operate web services that optimize AWS's global Internet traffic, enhancing network performance and availability while providing operational visibility and control capabilities. In this role, you will drive the technical direction and architecture of our software controllers that optimize hundreds of terabits of traffic leaving AWS. You will lead architecture decisions and design reviews, take ownership of platform operations at scale, and mentor engineers to raise the engineering bar. You will collaborate with both software and network experts, embodying best practices to create best-in-class solutions for our customers worldwide. Key job responsibilities - Lead the design and delivery of software systems end-to-end, from architecture through production, particularly traffic optimization and network control plane systems. - Leverage strong knowledge in data structures, algorithms, optimization, and complexity analysis to solve hard problems at global scale. - Define and raise engineering standards across the team — code quality, operational readiness, testing patterns, and documentation. - Communicate with other technical teams and management to collect requirements, describe software functionality, and build technical designs. - Mentor engineers and raise the hiring bar — grow the people around you and cultivate a culture of engineering excellence. - Influence technical strategy and investment decisions, partnering with principal engineers and leadership to shape where we invest next. - Own the operational excellence of critical systems, setting the standard for monitoring, alarming, and incident response. A day in the life - Lead design and code review sessions — writing and reviewing critical-path code, providing architectural guidance to the team. - Spend uninterrupted time writing code and prototyping solutions. - Meet with customers and other stakeholders to discuss their needs from our platforms, and help integrate their input into our plan. - Collect metrics and telemetry data to characterize the performance of our platform and identify improvement opportunities. - Write up design proposals for new features and drive collaborative review across the team. - Mentor team members through pairing, design discussions, and code reviews. About the team This opportunity exists within the AWS Internet Edge Services organization, where we build (SDN) software controllers which operate the network. This is a unique opportunity to build and innovate on one of the world's largest networks that delivers hundreds of terabits of traffic each day for our customers. Our team provides connectivity solutions for a wide range of use cases, such as retail (amazon.com), video streaming (Prime Video), content delivery (CloudFront), DNS (Route53), AWS services (such as EC2/S3), consumer devices (such as FireTV/Kindle/Echo), and more.
