ROBLOX is the #1 ranked kids web site in the US, drawing over one billion page views and 21 million in-game hours each month. A massively multi-player 3D game and building environment, ROBLOX emphasizes user-generated content. On ROBLOX, players use core building components to create elaborate online games that simulate the real world. They also build social hang-outs and groups for their friends, and custom virtual goods to sell in the ROBLOX virtual economy.

Join the team at ROBLOX and help us in our mission to build the best online game building site in the world. We are looking for exceptional people to take our leading 3D game community to even higher levels of technological sophistication.
