# Senior AI Engineer, Engine Reliability

Our engine, Titan, powers some of the highest-grossing games in mobile - titles that have generated billions in revenue and reach hundreds of millions of players. We are investing heavily in the future of Titan, and as part of that investment, we're building a brand-new Reliability team: an autonomous, high-skill group that will work closely with our engine and game teams, empowering them to work safer, faster, and easier through better infrastructure, AI-driven engineering capabilities, and feedback loops. AI is fundamentally changing how software is built, and we believe it will transform how games are made at Supercell. As AI agents take on more of the development process, the challenge isn't simply moving faster - it's building the confidence to do so. We're creating an AI-native Reliability team to help make that future possible, rethinking how we develop, validate, debug, and understand the impact of changes across real games. Our ambition goes far beyond better testing and automation: we're building the foundations for a world where engineers and AI agents can experiment, develop, and ship with a level of speed and confidence that simply isn't possible today.
