About The Position

Do you wonder what happens in the milliseconds between a user clicking play and
content appearing on their screen? Do you want to build the systems that make
that possible — at global scale, processing millions of requests per second?

Amazon CloudFront is looking for an experienced Software Development Engineer to
join our Routing Dataplane team in Seattle,
USA. CloudFront is one of the world's largest content delivery networks. Working
on systems with global scale is a daily part of the job. We build
reliable, scalable, low-cost systems that serve our ever-growing customer base.
We are constantly shipping features that drive innovation in the
CDN market. The environment is fast-paced, collaborative, and full of hard
problems worth solving.

This role sits at the intersection of distributed systems, networking, and
performance engineering. You will work on systems that operate at global scale
processing millions of requests per second and delivering content with high
availability, low latency, and strong security guarantees. You will build and
optimize critical dataplane components including layer 4 packet processing,
TCP/IP stack enhancements, DDoS detection and mitigation, and Anycast-based
routing systems.
-------------------------------
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.

A day in the life
You will work on systems that operate at massive global scale, solving complex
problems in networking, distributed systems, and real-time traffic
engineering. You will analyze network telemetry data to find and fix performance
bottlenecks, ship improvements to packet processing pipelines,
and collaborate with teams across AWS to influence how content is delivered,
secured, and optimized across the internet.
