Software Dev Engineer-II, Route 53 Resolver

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.

Amazon Route 53 is a highly available and scalable Domain Name System

(DNS) service offered by Amazon Web Services. We operate in over 50

locations worldwide and provide advanced functionality such as latency-

based routing (LBR), Private DNS, Geo DNS routing, DNS failover, and

integration with a plethora of AWS services. On top of that, we offer fast

change propagation with a 100% availability SLA. Our service is quickly

growing and we"re expanding in multiple directions: adding new features and functionality to our DNS services, better traffic management, new AWS integrations, improving our health check capabilities, and expanding with new services in the naming and routing space.

In the Amazon Route 53 team we like to "work backwards": start by

understanding what customers need and using that to guide our software

engineering. We are looking for a software development engineer who is

experienced in listening to customers, synthesizing their needs, and rapidly iterating our services to quickly put features into customers' hands by collaborating remotely with teams. Our best ideas become even better when we get feedback from real customer use. The sooner we can get that feedback, the more quickly we can grow.

Key job responsibilities

• Design and build highly available, low-latency distributed systems that power DNS and traffic management for customers operating at global scale, handling billions of queries daily.
• Own the full software lifecycle - from design and implementation through testing, deployment, and operational support - for critical services with stringent availability and performance requirements.
• Write high-quality, maintainable code in languages such as Java, Rust, or C++, and contribute to architecture decisions that improve scalability, resiliency, and efficiency.
• Solve complex technical problems involving networking protocols, fault tolerance, and large-scale data processing, balancing trade-offs between performance, cost, and reliability.
• Mentor junior engineers, participate in code and design reviews, and raise the technical bar across the team.
• Drive operational excellence by building monitoring, automation, and tooling that reduce operational load and improve system health.
• Collaborate with product managers, senior engineers, and cross-functional partners to deliver features that delight customers.

About the team

Amazon Route 53 team works on deep, technical problems that span a

variety of core topics in computer science ranging from databases to

networking to distributed systems to numerical analysis to security. Our

team has onsite and offsite engineers who collaborate remotely majority of the time. We are looking for a software development engineer who will lead the team and who feels strongly not only about building good software but also about running that software in the real world.
