You will own substantial parts of a simulation engine that powers continent-scale defence training environments — covering the behaviour and interactions of pedestrians, traffic, shipping, aircraft, satellites, and critical national infrastructure. You will shape how simulated actors decide and act, how simulation state stays coherent across a compute cluster, and how LLM-backed capabilities (natural language control, actor generation, simulated social media) are brought into the engine.
Work spans a C++ simulation engine, a custom distribution framework, and a TypeScript/React front-end, within a cross-functional team of Software, QA, and DevOps Engineers.
Key Responsibilities- Design and implement behaviour/decision-making logic for simulated entities in C++.
- Integrate third-party simulation libraries into a coherent system.
- Design simulation state partitioning across a distribution framework (IPC, bandwidth, fidelity).
- Extend REST services and TypeScript/React front-end across the web/sim boundary.
- Write design docs and run design reviews.
- Review peers' designs and code; collaborate with Product and defence stakeholders.
- Mentor teammates through pairing and code review.
- Deploy and support the product on-site at customer exercises, hackathons, and industry events.
- 4+ years software engineering experience.
- Experience in behavioural or agent-based simulation (game AI, VFX crowd sim, CGF, or similar).
- Strong C++ for performance-sensitive, real-time systems.
- Knowledge of spatial data structures, path planning, decision modelling, vehicle movement.
- Ability to reason about distributed simulation design (IPC, bandwidth, domain partitioning).
- Comfortable moving between languages and stack layers.
- Proactive, communicative style — able to challenge and draw out contributions.
- Product engineering mindset.
- Comfortable with AI-assisted development workflows.
- Eligible for UK SC-level security clearance.
- Able to attend Shoreditch office at least once per week.
- LLM-enabled product feature experience (NL interfaces, content generation, agent behaviour).
- Rust, particularly for distributed/systems-level work.
- Geospatial concepts and map data processing for simulation.
- Defence sector, military modelling/simulation, or wargaming familiarity.
- Kubernetes for compute cluster orchestration.
- Prior tech lead experience or interest in that pathway.
- Hybrid (1 day/week in Shoreditch).
- Private health insurance.
- Enhanced pension.
- Enhanced parental leave.
- 3 extra days off at Christmas (on top of 25 days).
- L&D budget.
- Regular socials.
- Share options.
