About The Position

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.

Do opportunities to work on ambiguous and never-solved-before problems excite
you?
Are you interested in scaling challenges that are constantly evolving? Would you
like to really contribute, both technically and as a leader in a team?

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 as part
of Amazon’s initiative to get EC2 performance to be as close as possible to that
of bare metal. This role would involve being part of the team that owns
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 a strong background coding in Linux, a
passion for improving quality, solving challenging problems and curiosity about
virtual networking, then 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.

What makes this team a great place to work? - Core VPC Team - Our services
underpin the fabric of the EC2 cloud. You have the opportunity to make a large
impact and drive the road map for the Amazon cloud.

- Opportunities for growth and leadership - You will have the opportunity to
work around both principal engineers and mentor more junior engineers, as well
as influence and shape the direction of the service.

- Direct Customer Contact – The Amazon way is to maintain and enhance what you
build. This gives you the opportunity to work directly with customers to
understand and guide their needs.

- Scale New Heights - With cloud adoption accelerating, we are challenged with
fun, complex problems to think about scale and grow the service to meet ever
increasing demands.

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. Our engineers collaborate across Amazon to solve
complex technical challenges while maintaining the highest standards for
availability, performance, and security.
