Riot engineers bring deep knowledge of specific technical areas but also value the chance to work in multiple broad domains. As a Principal Software Engineer on Research & Development working on an early stage product, you are armed with a wealth of knowledge in full stack game technologies, curiosity and an open mind for learning and knowledge work, and the flexibility to support rapid explorations during prototype.

As a Principal Software Engineer focused on Gameplay in Research and Development, you’ll build creative and fresh solutions that empower artists, engineers, and designers to iterate quickly, discover new play experiences, and then ship them at quality.
