Do you like building software systems that power the world's largest cloud network? Would you like to play a key role in developing the tools, automation, and data infrastructure that keep AWS network interconnects running at peak performance?

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.

The Core Networking team is looking for a Software Development Engineer II to join our Network Product Development (NPD) Interconnects Tools and Metrics (TMX) organization. In this role, you will design, develop, and operate the software systems that enable the NPD Interconnects team to monitor, qualify, and manage interconnect products across the AWS fleet. You will build and maintain tooling, automation, and data infrastructure across test infrastructure, observability and analytics, distributed systems for link operations, and ML model delivery.

This role requires strong software engineering skills, the ability to navigate ambiguity across multiple technical domains, and a passion for building scalable, reliable systems that directly impact network availability for AWS customers.

Key job responsibilities

• Design, develop, deploy, and operate software systems that enable the NPD Interconnects team to monitor, qualify, and manage interconnect products across the AWS fleet
• Develop and maintain automated test frameworks and tooling that enable product engineers to validate optical transceivers and fiber connectivity products, scaling test infrastructure to support increasing qualification demands
• Build and maintain data ingestion, processing, and storage systems for optics and fiber telemetry data, enabling product owners to conduct fleet-wide analysis through self-service tooling and dashboards
• Design and deliver distributed systems that orchestrate link-level testing, validation, and troubleshooting workflows across AWS regions, ensuring resilience and scalability
• Collaborate with Applied Scientists to build ML/science model serving infrastructure, operationalizing models that optimize fleet performance and predict failures
• Independently clarify requirements and deliver system-level solutions for technically complex or operationally ambiguous problems, with guidance from senior engineers on architectural direction
• Participate in on-call rotation, lead troubleshooting of production issues, and drive resolution for both individual and large-scale fleet events
• Automate and simplify team operations processes, improving service resilience and performance
• Produce high-quality, well-tested code, actively participate in code reviews, and mentor newer team members to raise the engineering bar
• Communicate effectively about technical work, document system architecture and operations, and collaborate across team boundaries to deliver features in services owned by other organizations

On an everyday basis as part of our team, you have the unique opportunity to understand the growing AWS network and our internal customers’ requirement on…
