About The Position

Amazon Interactive Video Service (Amazon IVS) is AWS's fully managed live
streaming service, built on the same battle-tested technology that powers Twitch
and trusted by thousands of enterprises across gaming, social, live commerce,
sports, and entertainment.

Our mission: enable developers to build communities around live video. We handle
everything from ingest to processing to delivery at global scale, so developers
can focus on creating interactive, engaging live experiences for their
audience. Whether you're streaming to tens of millions of concurrent viewers or
just getting started, Amazon IVS removes the complexity so developers can move
fast.

As a Software Dev Engineer III, you will design and build the systems that power
real-time and sub-second video distribution at massive scale. You will work deep
in the stack to ensure low-latency, high-reliability delivery for millions of
concurrent viewers. You'll collaborate with a team of engineers who care deeply
about performance, correctness, and scale, and you'll have the opportunity to
shape the architecture of next-generation streaming infrastructure.

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.
