Game Backend Programmer

Gaming and Production @ London

Our Purpose

Improbable is dedicated to building powerful technology designed to help solve previously impossible problems and enable the creation of new realities. In gaming and entertainment, Improbable unlocks truly next-generation gameplay through virtual worlds of unprecedented scale, persistence and richness. In other industries, we hope to help answer critical questions through simulations that could lead to a better functioning world.

Our platform, SpatialOS, lets developers transcend the limits of regular computation, allowing swarms of servers running in the cloud to cooperate in order to simulate worlds far larger and more complex than any single server could.

We are a British technology company proudly building a diverse workforce, driven by a shared desire to improve and achieve extraordinary things. We’re crafting technology for the future and fostering a problem-solving culture that embraces innovation through iteration and experimentation.
