System Development Engineer, AWS Networking

System Development Engineer, AWS Networking Overview

This role sits within AWS networking and focuses on the software, services, and internal tooling that keep one of the world’s largest cloud networks running. The position is aimed at an engineer who wants to build the cloud infrastructure itself, not simply use it, and who enjoys working on the systems that enable network automation, reliability, and operational efficiency.

As a System Development Engineer, you will work in a fast-moving, highly collaborative environment with a start-up feel. Your work will support network engineering teams by deploying, maintaining, repairing, and rethinking the software components they depend on to automate the AWS network and keep it operating smoothly. You will also help create new software solutions that address the challenges of running AWS networking at global scale.

What you will do

• Track down and resolve difficult problems in systems, processes, and tooling so the network organization can operate more effectively and deliver better outcomes for customers.
• Build entirely new software components, products, or services that improve operational efficiency and strengthen the way the network is managed.
• Investigate technical incidents thoroughly, determine the underlying cause, and implement long-term corrective actions to prevent repeat failures.
• Improve testing, monitoring, and validation across services, tools, and infrastructure so new releases can be deployed continuously with minimal interruption.
• Own and improve team services from end to end, including troubleshooting issues and identifying the root cause within the systems themselves.
• Invent and refine automation and tooling that reduce manual operational work across teams.
• Make practical engineering trade-offs that support both immediate operational needs and future business requirements.
• Develop solutions to technically complex business problems in a large global organization.
• Collaborate closely with network engineer colleagues, who are the internal customers for the team’s software and platforms.
• Contribute to an Agile working style and help advance the software tools and services that underpin AWS network operations.
