Games Ecosystem Engineer

London | Partner Engineering

Help us transform what multiplayer games can be. Our engineers are changing how online games are made, operated and played. Join them, and be part of a team with credits on some of the biggest game titles, with diverse backgrounds ranging from art to aerospace. You'll address the toughest engineering challenges. You’ll co-develop with world-class studios, and build games that challenge the limits of the possible.

At Improbable, we believe that the next revolution in entertainment and society will come from massive virtual worlds. They’ll create new economies and opportunities globally, changing not just how we play, but how we work and relate to each other. That’s why we’ve made it our mission to build the next generation of technologies for online multiplayer games and simulations.


At Improbable, you’re 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:

Our product, SpatialOS, is a state-of-the-art platform for simulating potentially many instances of a game world. SpatialOS addresses many concerns, including the effective distribution of information and work to user-specified simulation processes, the persistence of in-game data, the horizontal scaling of game worlds, client-side platform agnosticity and tools to improve developers’ effectiveness.

To offer these capabilities, we have built several sets of tools, accompanying game developers in all phases of the game lifecycle. These tools cover building and iterating locally, distributing clients, starting remote services or monitoring a live game in production. We also want to offer our customers  - game studios all over the world - the flexibility to utilize third party tooling and solutions in addition to Improbable’s online services listed above. They can mix and match based on their game’s requirements.

You will have the opportunity to deep dive into games of all genres to help design and integrate the best solution for their specific needs. On some projects, you’ll implement a new portal to these existing and future services, unifying them under a common user experience. 

Areas of Impact:

  • Using your extensive engineering expertise, you’ll enable game studios to build fantastic player experiences and by integrating our ecosystem, enable game publishers to make it easier for their studios to create.
  • As an experienced Engineer, you will play a key role in teaching and mentoring other engineers within the team to help nurture and grow them
  • You will work directly with our customers, to understand their requirements and translate that into the design, build, and integration of the various online services they require 
  • You will work with a range of commercial and proprietary game engines, building high quality integrations with a suite of online systems and components.
  • You will work with and integrate with the wider Improbable Engineering teams. This will give you the opportunity to work with a breadth of programming languages, such as Go and C#, along with open source technologies, such as Docker and Kubernetes. 

We would like to hear from you if you identify with Any of the following:

  • Experience working with large game engine codebases such as Unreal Engine, Unity or CryEngine
  • Experience working with online services SDKs such as Steamworks, Epic Online Services, PlayFab and GameSparks
  • Experience working with large scale systems (C++, Go, C#, or Node.js) of an online nature
  • Experience developing supporting systems for online games such as voice and text chat, auth services, matchmaking, social interaction systems, and telemetry engineering
  • Experience working in all phases of game or services development, from feature design to bug-fixing 
While we think the above experience could be important, we’re keen to hear from people that believe they have valuable experience to bring to the role. If you identify with the team and mission, but not all of our requirements, then please still apply!!
