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

Riot Games•Los Angeles, CA

About The Position

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. As a Senior Software Engineer on the Behavior Evaluation and Moderation (BEAM) team, you’ll collaborate with engineers, game designers, product managers, and data scientists to develop backend services and solutions that support Riot’s current and future games in a scalable way. You’ll contribute to the implementation of features, following established designs, and work closely with teammates to ensure quality and maintainability. You’ll also participate in on-call rotations to support live services and help maintain high availability for our systems. You’ll embrace the team’s values by focusing on high-impact work, using data to inform decisions, and collaborating across disciplines to create the best possible experiences for players. You’ll help improve team processes, write reliable code, and continue to grow your skills with guidance from senior engineers.
