The Role

As a Simulation Software Engineer , you will own substantial parts of the simulation capability that makes continent-scale defence training feel like the real world - the behaviour and interactions of pedestrians, traffic, shipping, aircraft, satellites and critical national infrastructure that populate a scenario.

This is the difference between an exercise that feels like a map overlay and one that reacts to a trainee’s decisions with the emergent complexity of actual people, systems and infrastructure. You’ll shape how simulated actors decide and act, how the simulation stays coherent when partitioned across a compute cluster, and how new LLM-backed capabilities - natural language control, richer actor generation and simulated social media - are brought into the engine.

Your work will ship into customer exercises, live demonstrators and integration hackathons, where the loop between building something and watching users bend it to ...
