The opportunity

Connected real-time applications are rapidly becoming ubiquitous across social, entertainment, and many industries. Game developers repeatedly say that multiplayer game creation remains one of their hardest challenges; balancing ease-of-use with performance and flexibility remains unsolved. As a result, we’ve seen far too little innovation in multiplayer games over the last decade, while creativity in single-player games has thrived.

At Unity, our customers build all kinds of experiences not only across game genres but beyond games as well. Our multiplayer solutions need the versatility to meet the demands of these applications, enabling new and larger experiences to be made.

Join a team dedicated to creating a performant & flexible networking stack, and a modern development experience tailored to multiplayer games.

What you’ll be doing

  • Provide architectural direction for a netcode SDK and associated libraries that prepares us well to grow our offering over the years across GameObjects and Entities.
  • Work across multiple teams to lead an effort for a consistent product experience across netcode stacks, dedicated server, multiplayer tooling, and educational and marketing samples.
  • Develop systems covering everything from lag compensation to game object replication
  • Design high-level systems integrated with the Unity Editor & Unity Engine
