About the job

About MetaGravity

MetaGravity is a deep-technology startup headquartered in London which is solving the concurrency problem in simulation for massive virtual worlds and games. Current game engines and game servers can handle a peak of ~100 players in a self-consistent “instance”. However, the next generation of online games and metaverse experiences demand much larger simulated realities beyond what is currently feasible — think, tens of thousands to millions of players and AI beings! MetaGravity is solving this problem. We’ve worked from first principles to build distributed computing infrastructure that is limitless in its ability to scale, thus empowering creators to craft truly living, breathing worlds.

Our team is composed of seasoned entrepreneurs and innovators with decades-long experience in distributed systems, supercomputing, game engine development and AAA game production. We are deeply committed to our cause, believe in its immense upside potential and embrace bold, first-principles thinking in our approach to problem-solving.
