Job summary

Amazon Shield (Ant-DDOS) at AWS Infrastructure Services seeks a Sr Software Development Engineer to design, build, and operate internet-scale distributed systems defending AWS infrastructure against sophisticated DDoS attacks.

You will mentor engineers, collaborate with software, hardware, network, and security teams, and drive high-stakes decisions to ensure safe, reliable traffic and scalable mitigation in a fast-moving threat landscape.

Qualifications

• 5+ years of non-internship professional software development experience.
• 5+ years of programming with at least one software programming language experience.
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience.
• Experience as a mentor, tech lead or leading an engineering team.

Responsibilities

• Lead the design, development, and operation of internet-scale distributed systems that defend AWS infrastructure and millions of customers from sophisticated DDoS attacks.
• Architect and build high-throughput systems that process and protect traffic representing a substantial portion of global internet activity.
• Drive technical solutions for scaling challenges that few engineering teams ever encounter—handling traffic volumes and attack patterns at the boundaries of distributed systems design.
• Design creative, forward-looking mitigations in an ambiguous, fast-moving threat landscape where attacks evolve daily and solutions must anticipate what doesn't yet exist.
• Own high-stakes engineering decisions that balance massive scale, rapid iteration, and effective mitigation while ensuring customer traffic flows safely and reliably.
• Mentor and raise the bar for engineering excellence across the team through code reviews, architecture guidance, and technical leadership.
• Collaborate with cross-functional teams of software, hardware, network engineers, and security experts to deliver the highest standards of perimeter protection.

Job description

Sr Software Development Engineer, Shield (Anti-DDoS)

Job ID: 10499020 | Amazon Development Center U.S., Inc.

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.
