Riot Games was established in 2006 by avid 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. Players form the foundation of our community and it’s for them that we continue to evolve and improve the League of Legends experience, and beyond! We’re looking for passionate professionals who can teach us a thing or two. We promise to return the favor. We embrace those who see things differently and aren’t afraid to experiment. That's where you come in.

Riot's Data developers build tools to understand and delight our worldwide players using petabytes of data and state-of-the-art data processing technology. Handling the potential these data offer is a tremendous and complex task. As we continue delivering and scaling content to passionate gamers, our discipline has challenges and opportunities centered on crafting, building, and maintaining data products that support our growth. Whether you are a Data Scientist modeling game systems, a Data Engineer bringing scale and efficiency to systems, or a Data Architect organizing data in ways that make data products more player-focused and dependable, we need you to help push forward our “Player Experience First” goals.
