User Experience Designer jobs in United States

Established in 2020, the Singapore Studio is Riot’s second international game development studio. Riot has been expanding our footprint in Asia and accelerating our talent growth to develop games that deliver great experiences to our players. Our mission is to “scale Riot’s games to hyper-serve players.”

We partner with our LA headquarters on game development for League of Legends, Teamfight Tactics, and Legends of Runeterra. We’re also building teams for VALORANT and 2XKO, our upcoming fighting game. The Singapore Studio is seeking talented, passionate craft experts with backgrounds in all areas of game development to build games that make it better to be a player.

We’re focused on working together to promote individual autonomy, ownership, collaboration, and inclusivity, so everyone can be their best while we boldly pursue games.

That’s where you come in.

As a Senior Backend Engineer on the Metagame team for 2XKO, you will be a key contributor to building the systems and services that support our players outside of the core fight. From progression and competitive features to content systems and player identity, the metagame is where long-term engagement lives.

You’ll be responsible for designing, building, and maintaining scalable backend systems that power these experiences. You’ll collaborate across disciplines (designers, artists, producers, QA) to help deliver features that are reliable, maintainable, and exciting for players. Your deep backend expertise will shape how we architect, test, scale, and operate our services in production.
