Lead Unity Engineer, Games
 London, KY
Improbable believes in a future where new, virtual worlds will augment human experience and become as meaningful, lasting and rich as the physical world. We call this the Multiversal Self.

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.

At Improbable, you are surrounded by people who want to improve everything and everyone around them, and who compel you to improve yourself. We’re motivated by the fulfilment of solving hard problems to achieve something profound and transformative.

Your Mission

“Provide seamless access to the unique capabilities of the SpatialOS platform for all Unity developers and empower them to build the innovative games and applications of tomorrow” 

We strive to enable Unity and mobile developers to quickly and easily build and host multiplayer games. As the Engineering Lead, you will manage the team and drive the continual advancement of our SpatialOS Game Development Kit (GDK) for Unity.

You will play a critical role in leading our small, fast-moving engineering team. The team is  responsible for defining and implementing the concepts and workflows that Unity developers use to access our platform, build their game, launch, debug and analyse its performance.

Whilst remaining hands on and contributing towards the development of the GDK, your primary role is to lead and develop your wonderful team - taking care of hiring, on-boarding, mentoring, coaching, career development, and performance management. We want to build a positive team culture where you're supporting colleagues and empowering them to grow as technical leaders and people.
