Software Development Engineer (L5)

Job ID: 1840070 | Services LLC


Luna is Amazon's cloud gaming service where it's easy to play great games on devices you already own. No waiting for lengthy downloads or updates — just play.

The Luna core streaming team is responsible for making sure that games run efficiently to delight our customers. Broadly, this role involves working with graphics libraries and GPUs, A/V encoding and decoding, custom network protocol and network congestion algorithms. Specifically, this role involves working with Proton - a compatibility layer to run Windows games on Linux using Wine. Luna is committed to working with the open source community around Proton. This role will commit code to open source projects such as Proton and Wine in pursuit of running games in a stable and performant manner.

The ideal candidate will have a strong background in Linux - both with systems level programming and the ability to diagnose performance bottlenecks and resolve them. Equally important is a strong background in C/C++. Wine exclusively uses C, so a bias towards expertise in C is preferred. Finally, expertise with the Windows operating system and game engines is a bonus.

If you’re passionate about creating delightful gaming experiences, love open source, and love to fix performance bottlenecks, we would love to hear from you. The Proton community values passion for gaming over specific technical skills and Luna is no different. Even if you only know some of the technologies listed, if you're passionate about gaming, please apply.

Buzzwords for the role: OpenGL, Vulkan, Direct3D, Mesa, Proton, DXVK, Wine, C, C++, Linux kernel, Windows kernel.

A day in the life

You will solve hard technical problems in Linux graphics stack, starting from Linux Kernel to graphics libraries. You will work in graphics technologies like DirectX, Vulkan, DXVK, and OpenGL. You will dive deep into graphics performance issues and provide solutions that enable Windows games run on Linux, and make contributions to open source Wine/Proton. You will have the chance to invent your way out of novel challenges in game streaming paradigm.
