In 2009, Riot released its debut title League of Legends and over 100 million people now play the game every month. 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 Security Engineers and Analysts hold an in-depth knowledge of specific areas of expertise. We don't just focus on breaking things; we aggressively support teams across Riot to develop robust security capabilities which help protect player experiences. We relish the opportunity to work with new tech stacks and product teams, each with their own particular security risk profile and complex challenges.

At the most fundamental level, our goal is to help deliver value to players and make life harder for troublemakers.

As an Application Security Engineer, you will work closely with product teams globally to help build fun, safe and secure experiences for players. You will identify application security gaps and own projects to address them. Your deep knowledge of both the technical detail and player impact of security vulnerabilities will help you communicate potential issues to Rioters and improve the security of the player experience.
