Software Development Engineer, Data Center Host Monitoring

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.

Key job responsibilities

• Design, build, and operate distributed services that are reliable, scalable, and maintainable at global scale
• Own your services end-to-end - from architecture and implementation through deployment and production operations
• Identify and drive improvements to system reliability, latency, and operational posture
• Contribute to team engineering standards, code reviews, and technical direction
• Mentor junior engineers and contribute to a culture of high engineering quality

About the team

Every server in every AWS data center is continuously generating signals - thermal readings, reachability status, power metrics - and it"s our team"s job to make sure that data is collected, processed, and acted on in real time. We build and operate the monitoring systems that give data center operations teams visibility into the health of AWS"s global infrastructure, and we power the alerting systems that notify operations staff when something needs their attention.

As an SDE on this team, you"ll own and evolve distributed services spanning availability monitoring, hardware telemetry pipelines, and anomaly detection and alarming - the systems that serve as the first line of detection when something goes wrong in a data center. Your customers are internal: the engineers and operators who work hands-on with physical infrastructure every day. That means tight feedback loops, fast iteration, and the chance to sit down with the people actually using your systems to understand what"s working. Real Customer Obsession, not the abstract kind.
