Software Development Engineer, Route 53

About the role

You will design, build, and operate globally distributed systems that enable millions of customers to securely and reliably resolve DNS queries within milliseconds—across regions, VPCs, on-premises environments, and hybrid/multi-cloud architectures. This is an opportunity to work at the intersection of networking, security, and distributed systems at massive global scale. You will get an opportunity to work across the full stack—control plane, data plane, API surfaces—and integrate with core AWS infrastructure services. You will also help drive system architecture decisions, champion engineering best practices, and mentor junior engineers on the team.

Responsibilities

• Design and implement highly available, low-latency distributed systems that serve DNS traffic at global scale
• Build and operate secure, resilient services that protect customer workloads across hybrid cloud and multi-cloud environments
• Develop control plane and data plane components, APIs, and integrations with AWS networking and security services
• Architect solutions that support containerized workloads, microservices, and modern cloud-native application patterns
• Contribute to the security posture of the service, including DNS Firewall capabilities, encryption, access controls, and threat mitigation
• Operate services in a DevOps model with a focus on automation, observability, and operational excellence
• Participate in on-call rotations and drive root cause analysis for production issues
• Mentor and develop junior engineers through code reviews, design discussions, and technical guidance
