Software Development Engineer, EC2 Software Defined Networking, VPC Core

Job  | Amazon Development Center U.S., Inc.

AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. We keep the cloud running by supporting all AWS data centers and all of the servers, storage, networking, power, and cooling equipment, ensuring 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’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 deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. You’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

The Amazon Elastic Compute Cloud (EC2) Networking team is looking for software engineers who have a passion for diving deep while also being able to see the big picture. We are re‑engineering our virtual networking control plane to get EC2 performance as close as possible to that of bare metal. This role involves building, scaling, and maintaining high‑performance software to streamline the management of millions of Virtual Private Cloud (VPC) configurations.

If you are a Software Engineer with strong background coding in Linux, a passion for improving quality, solving challenging problems, and curiosity about virtual networking, this is your opportunity to own major deliverables and all aspects of the development cycle: scoping, design, implementation, and testing. You will be encouraged to exercise judgment in proactively determining and recommending the best features, designs, and support models based on business objectives, timelines, and resource constraints.

• Design, develop, and maintain scalable systems and services for Amazon EC2 (VPC), ensuring high availability and performance for millions of customers worldwide
• Build and optimize networking infrastructure components including subnets, route tables, security groups, and network ACLs to enhance customer experience and system reliability
• Collaborate with cross‑functional teams to define technical requirements, architect solutions, and deliver features that improve VPC functionality and customer workflows
• Write clean, maintainable code and conduct thorough code reviews to maintain high engineering standards across the team
• Troubleshoot complex distributed systems issues, perform root cause analysis, and implement long‑term solutions to prevent recurrence
• Participate in on‑call rotations to ensure 24/7 operational excellence and rapid incident response for VPC services
• Mentor junior engineers through code reviews, design discussions, and knowledge sharing sessions
• Contribute to technical documentation, design documents, and operational runbooks to support team knowledge and service maintainability
• Drive continuous improvement initiatives to reduce operational burden, improve system performance, and enhance monitoring and alerting capabilities

The EC2 VPC team builds and operates the foundational networking infrastructure that powers Amazon’s cloud computing platform. We design and maintain highly scalable, reliable systems that enable customers to create isolated virtual networks within AWS. Our team is responsible for core networking components including subnets, route tables, security groups, and network ACLs that serve millions of customers globally. We focus on delivering exceptional customer experiences through continuous innovation, operational excellence, and building robust distributed systems.
