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.

• 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.
