Senior Software Engineer - Publishing Platform, Social: Behavior Evaluation and Moderation at Riotgames

Riot engineers bring deep knowledge of specific technical areas but also value the opportunity to work in a variety of broader domains. As Software Engineers, we work with both new and current technology, creating innovative solutions to overcome high-volume obstacles and to deliver player value. Riot builds genre-defining games and people love to play them, but for some players, their experience can be diminished by disruptive social interactions. The Behavior Evaluation and Moderation (BEAM) team, part of the Social Initiative on Player Platform, works to foster positive player-to-player experiences and reduce negative behavior, empowering players to have the experience they want. We also enhance pro-social spaces to create more engaging and welcoming environments.
