Today, Build lets you do all of this through text: generate a playable game from a sentence, iterate on gameplay and visual design, playtest the changes, publish, and discover insights to help your game grow. From here, we are making the iteration cycle faster, gamifying the act of building, and helping get creators' work in front of players. These efforts lower the barrier to creation and make Roblox a place where anyone can turn an idea into a game people play. Your work will have a direct impact on millions of Creators by making creation more powerful, accessible, and seamless. We primarily work with React, Luau, and occasionally C++, but adaptability to evolving technology is key. TypeScript and Web expertise are a helpful proxy for this stack.
