Every day, tens of millions of people from around the world come to Roblox to play, learn, work, and socialize in immersive digital experiences created by the community.

Our vision is to build a platform that enables shared experiences among billions of users. This is what’s known as the metaverse: a persistent space where anyone can do just about anything they can imagine, from anywhere in the world and on any device. The breadth of opportunities, and the evolving demands of this first-of-its-kind platform, ensure that your avenues for growth are always expanding and flexible.

Join us and you’ll usher in a new category of human interaction while solving exceptional challenges that you won’t find anywhere else.

As a Senior Graphics Engineer, you will be working on foundational algorithms for real-time 3D avatars that will scale to the millions of users on the Roblox platform. Our team, composed of industry experts from ILM, Digital Domain, Adobe and Google, are working on challenging engineering problems at the boundary of real time computer graphics and deep learning. One such project is discussed in our SIGGRAPH ‘21 talk that describes our approach for building a mobile-friendly real-time facial animation system.

The technologies we envision will allow Roblox players to watch their favorite music artist singing with facial expressions in real-time during a virtual concert or interacting with friends in a life-like, interactive way. The expression of emotions that will be brought to life by the Roblox community is limitless.

Our team is led by Kiran Bhat, who was the co-founder of Loom.ai (acquired by Roblox) and won a SciTech academy award for facial capture used in several feature films, including the Hulk in the Avengers. The avatar emotion team is working on projects to bring the magic of digital characters and real-time emotion capture to the Metaverse to allow our users to project their identity and express themselves through their digital avatars.
