Riot Games was established in 2006 by entrepreneurial gamers who believe that player-focused game development can result in great games. In 2009, Riot released its debut title League of Legends to critical and player acclaim. As the most played video game in the world, over 100 million play every month. Players form the foundation of our community and it’s for them that we continue to evolve and improve the League of Legends experience.

We’re looking for humble but ambitious, razor-sharp professionals who can teach us a thing or two. We promise to return the favor. Like us, you take play seriously; you’re passionate about games. We embrace those who see things differently, aren’t afraid to experiment, and who have a healthy disregard for constraints.

That's where you come in.

Data Scientist

As a Rioter in China, you'll join a team of internationally and culturally diverse professionals that share our prioritization of player experience, rejection of convention and maniacal passion for gaming. 

To reinforce Riot’s collaborative culture in our China offices, we’ve decided to do away with the constraints of traditional hierarchical title structures that are more common in the region. Titles don’t really matter at any of Riot’s offices, but we chose to take this extra step in our China offices to foster a space where teamwork thrives. We believe that removing this constraint will promote individual autonomy, ownership, collaboration, and a focus on results. We promise you won’t need a title at Riot to make an impact.

As a Data Scientist in our Shanghai office, you leverage your Data Science expertise to help Riot maximize our technical partnership with Tencent. You’ll focus on these 3 critical initiatives:
