In 2009, Riot released its debut title League of Legends to worldwide acclaim. The game has since gone on to become the most played PC game in the world and a key driver of the explosive growth of esports. Whether you're in Rio, Seoul or Moscow, you can find an excited and engaged community of League players. Delivering content to a global audience of millions of players whilst also building new games affords Riot's Engineering discipline with a mountain of exciting and technically complex challenges. That's where you come in.

Riot engineers bring deep knowledge of specific technical areas but also value the opportunity to work in a variety of broader domains. As a Software Engineer, you’ll work with both new and current technology, creating innovative solutions to overcome high-volume obstacles and to deliver player value.

As a Software Engineer on the Game Flow Services team, you’ll report into the team’s Engineering Manager in our office in St. Louis, Missouri. You'll write core backend services to keep scaling League of Legends for our players. We'll need your expertise with platforms and microservices to design robust and reliable systems that are easy to understand and operate. You’ll also draw on your experience with engineering best practices to ensure that our testing and deployment tech is always improving. Finally, you’ll sharpen your eye for player value by proposing new features and by fixing tech debt that is slowing us down, and as League of Legends continues to grow, you’ll know that your code is the foundation that makes it all possible.
