Senior Software Dev Engineer, Shield

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.

Join Shield, AWS's defense team within Perimeter Protection. We stand at the forefront of protecting AWS infrastructure and millions of customers from sophisticated attacks across the internet. Our mission is critical: safeguard the cloud infrastructure that powers a significant portion of the modern internet.

What Makes This Role Exciting:

Internet-Scale Impact: Process and protect traffic representing a substantial portion of global internet activity. The systems you build will defend some of the world's most critical infrastructure.

Scaling Challenges: Work on problems that few engineering teams ever encounter. Handle traffic volumes and attack patterns that push the boundaries of distributed systems design.

Creative Problem Solving: Operate in an ambiguous, fast-moving space where the threat landscape evolves daily. Your creativity and adaptability will be your greatest assets as you design solutions for attacks that don't exist yet.

High-Stakes Engineering: Balance competing priorities - massive scale, rapid iteration, effective mitigation - while ensuring customer traffic flows safely and reliably. Every decision matters.

Key job responsibilities

• Design the future of AWS security architecture
• This position isn't about maintaining existing systems, it's about architecting the next generation of protection mechanisms that will defend AWS and its customers for years to come
• You'll be working on existing and greenfield projects that will shape how we detect, mitigate, and prevent attacks at unprecedented scale and in real-time
• Members of the team work closely across research and DDoS response teams, to build the solutions to stop Layer 3/4 and Layer 7 attacks more effectively

About the team
Shield is our advanced DDoS mitigation system that provides network protection to AWS infrastructure at global scale. The control plane is the orchestration layer that coordinates protection across AWS's worldwide network.

The Shield Control Plane enables automated deployment and monitoring of DDoS mitigations, ensuring rapid response to threats while maintaining high availability. This system processes configuration changes and provides real-time visibility into mitigation effectiveness across our global infrastructure.

Working on the Shield Control Plane means building and operating critical systems that protect AWS's global infrastructure from sophisticated attacks on the internet.
