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

The Application Platform Team manages the core infrastructure and API stack that powers https://www.roblox.com. Also, the team owns shared libraries, infrastructure microservices, and the JavaScript frameworks used by all other Roblox full-stack feature teams. We ship with testable and configurable features that allow for rapid experimentation, data collection, and optimize for performance and user engagement.

Here are a few quick highlights of how we power Roblox:

CDN - we push hundreds of petabytes of data through our CDNs each month
Microservices - we manage 50+ microservices, the most of any Roblox full-stack engineering team
API Scale - we run services that hit 500K - 700K RPS, the highest load of any Roblox full-stack engineering team.
Thumbnails - our system generates 20,000 - 50,000 thumbnails at peak. Perfect for viewing all your avatar clothing options!
