Description

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.

As a Sr. Software Development Engineer at AWS, you are driving a wave of innovation and bringing sweeping changes to the way we manage our networks. You are developing software that allows us to build the most reliable, available and self healing network in the world. On a daily basis you work closely with your teammates and surrounding teams to bring adaptive and creative solutions to operational and business goals. At AWS, we are pushing the boundaries of what we can achieve every day, and we are a highly motivated and collaborative team of engineers who thrive on solving challenging problems.

Virtualization, incredible scale, hardware commoditization, and automation are revolutionizing networking and network software. In AWS Networking, we leverage big data technologies and analytics software to run one of the largest networks in the world. We push the boundaries of robustness, fault-tolerance and smart adaptive algorithms that can react intelligently to real-world events. This is your time to make history by building large-scale distributed software systems.

CloudWAN is a global network management product which operates at massive scale and simplifies customer's connectivity, operations, and visibility. A Sr. Software Engineer on the CloudWAN team will develop new features and services; refactor for scale and performance; interact with customers and our product team; and mentor and develop other engineers.
