Team, about the role

We’re building a cutting-edge AI team inside one of the fastest-growing projects at Playrix, a top-grossing title in the global mobile games market.

Our goal is to bring generative AI into the art pipeline, helping artists scale creativity while maintaining a consistent visual style across a huge volume of content.

We’re looking for a Generative AI/ML Engineer (СV/LLM) who’s excited to work at the intersection of technology and visual storytelling. You’ll have the chance to experiment with the latest in diffusion models, fine-tuning, and style control, and to build tools that go straight into production — used by a top-tier art team creating content for tens of millions of players.

This role requires relocation from Russia and Belarus to one of our offices or remote work from other countries (except Russia and Belarus). Find out more here.
