Game Rendering 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.

Your Mission

With the successful launch of SpatialOS to the gaming world, the popularity of our platform is growing. Our goal is for our partners to be able to successfully launch.

As a Game Rendering Programmer you will develop new techniques for real-time rendering from R&D inception to production usage. You will deliver tools and technology that empower the next generation of video games. You will set new bars for what can be achieved with real-time rendering.

A great advantage of working at Improbable is that you are constantly engaging with new genres of games which are using either the commercial engines like Unreal/Unity/CryEngine or bespoke engines. So, you can grow your expertise and influence across multiple engines. You will find ways about why the graphics quality of a certain engine is better over the other and use your learnings to architect a better performing and better quality game overall.

You'll also be responsible for optimising rendering performance for different specs of hardware, to achieve the best possible visual fidelity on all our target platforms at a high frame-rate. With our SpatialOS platform we can render huge worlds and massive number of players. We are facing challenges never seen before in video games and hence we need you to push the boundaries.
