Principal Rendering Engineer

Join some of the best Graphics Engineers in the world supporting the largest immersive 3D streaming environment deployed across console, desktop, mobile, and VR.

• Scalability: Roblox provides a platform that guarantees to the creators that their games will always and automatically run on different devices, with cross-platform play and minimal load times.
• Compatibility: Roblox games and assets made in the past, are still working today. Rendering has to have an eye to the past, and an eye to the future…
• Community: Roblox games are made by creators of all experience levels, from professionals who earn their living on the platform to kids who are learning to program using Roblox!

As a Rendering Engineer, you will solve difficult challenges, while continuing to build a high-speed, completely dynamic environments connected on all devices.

Many established rendering techniques do not trivially apply to our platform - novel solutions are needed as we push Roblox towards higher targets of visual fidelity. Even the simpler visuals we support on low-power devices are enabled by some creative rendering ideas, often centered around caching, incremental computation and graceful degradation.

All of this is based on an in-house rendering engine built from the ground up, supporting DirectX 9/11, OpenGL, GNM, Metal, and Vulkan GAPI's. We have a powerful need for top-notch, low-level and high-level graphics work.

You Will:

• Help investigate and implement rendering techniques to make ROBLOX graphics more immersive and expressive
• Learn about our community and work with technical artists to understand the present and future needs of our creators
• Help improve the performance and stability of our game engine
• Work with other engineering and art teams
• Take ownership of a project throughout its full lifecycle

You Have:

• Knowledge of C++ and shading languages
• Knowledge of 3D math and computer graphics related algorithms
• Knowledge of one or more GPU APIs (OpenGL, DirectX and similar)
• The ability to reason about code performance and memory consumption
• 6+ years experience in real-time rendering
• Interest in creating creative rendering techniques
• Passion about the state-of-the-art in rendering research
• Mobile or console development experience
