Senior Anti-Cheat Engineer - Central Technology, Anti-Cheat

Riot Anti-Cheat Engineers are versatile and passionate about their craft. We understand the player impact of cheating in games and are focused on setting the highest bar for the integrity of multiplayer games. We relish the opportunity to work with low-level systems and take pride in developing creative, rigorous defenses against adversaries. At the most fundamental level, our goal is to promote the best player experience by protecting the legitimacy of their favorite games.

As a Senior Anti-Cheat Engineer, you will be responsible for the ongoing development and evolution of Vanguard Anti-Cheat’s client services. With versatility across user-mode, kernel-mode, and obfuscation tooling services, you’ll work primarily in C/C++ and x86/x64 assembly to build new anti-cheat features, improve the security and reliability of existing systems, and debug complex behavior across the Windows stack. You’ll also reverse engineer emerging cheats, including packed and obfuscated binaries, and rapidly translate those findings into practical detections, mitigations, and preventative controls. You'll be based in our Santa Monica, CA office and work in a hybrid (work-from-home and in-office) environment. You'll report to the Sr. Manager of Anti-Cheat Engineering.
