Roblox just made a big hire it hopes can unlock its next stage of growth.

The online entertainment and gaming platform exclusively told CMO Insider it had appointed John Ciancutti as its first-ever chief growth officer.

Ciancutti is responsible for Roblox's discovery team, which works on its TikTok-like algorithm that recommends games and experiences to users most likely to play them. Roblox is a virtual universe available on mobile devices, desktops, and video game consoles that allows users to play and design games and other online experiences.

Ciancutti is also charged with leading the company's international growth, including its expansion in China.

He joins Roblox at a crucial moment.
