Some projects we’re planning for the near future that you will have direct impact on:

  • Dynamic sky
  • Physically-based shading
  • Compute, shader-based lighting system

All of this is based on an in-house rendering engine built from the ground up, supporting DirectX 9/11, OpenGL, GNM, and Metal API’s, with Vulkan in the works. We have a powerful need for top-notch, low-level and high-level graphics work. The games on the ROBLOX platform are completely dynamic -- anything can change at any time -- and our rendering engine has to excel in this dynamic environment.

  • Shader development in High Level Shader Languages (HLSL) or equivalent
  • A strong desire to learn ROBLOX infrastructure and build new features to improve the quality of our product
  • Self-sufficient, self-organized, and able to take ownership of a project throughout its full lifecycle

Nice to Have:

  • Low level rendering API’s such as Metal and Vulkan
  • Previous experience designing and coding a game engine from scratch
