About this role
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, build, and operate internet-scale distributed systems that protect AWS infrastructure and millions of customers from sophisticated attacks - Process and defend traffic representing a substantial portion of global internet activity across AWS's perimeter protection layer - Architect solutions for traffic volumes and attack patterns that push the boundaries of distributed systems design - Develop creative mitigations for evolving threats in an ambiguous, fast-moving landscape—including attacks that don't yet exist - Balance competing engineering priorities—massive scale, rapid iteration, and effective mitigation—while ensuring customer traffic flows safely and reliably - Collaborate with cross-functional teams of software, hardware, network engineers, and security experts to deliver the highest standards of safety and security - Contribute to operational excellence through code reviews, architecture discussions, and production troubleshooting - Drive continuous improvement of detection and defense capabilities at the forefront of internet security A day in the life 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.
