Guerrilla, the Amsterdam-based developer of Horizon Zero Dawn, is looking for a Network Engineer to support us is in the making of an exciting unannounced title.

Our Game Tech team

Our Game Tech team builds reliable, maintainable and performant game systems. We work with e.g. gameplay programmers, designers and artists to give them the tools they need to build the game. Among other things, we deliver an animation system, a visual scripting system, part of the cinematic pipeline, high level streaming systems, the physics engine integration, an analytics framework as well as the networking layer for both game client and server.

Our Online Tech

To sync multiple game clients in real time we’re using C++ and a custom UDP based protocol. All clients connect to a messaging hub which relays any message sent to it to all other players (hiding player IPs and preventing firewall issues). This hub runs on Linux on Amazon EC2. For everything that is not latency critical we use industry-standard web technologies: Java, Tomcat and Spring.
