C++ Software Engineer – Modelling & Simulations

C++ Software Engineer – Modelling & Simulations
We are seeking a Software Engineer to help create and improve large-scale models and simulations, supporting decision-makers in areas such as urban planning, transport, and infrastructure. You will work as part of a multidisciplinary team to develop high-performance simulation software, integrate data pipelines, and ensure that models can run efficiently at scale.

Key Responsibilities:

• Work with applied scientists to take models from prototype stage to production-ready software.
• Develop and implement computational models for large-scale social and urban “Digital Twin” simulations.
• Build and optimise data pipelines to extract, synthesise, and integrate data from various sources.
• Scale and refine agent-based models incorporating real-world data and complex behaviours.
• Track and improve model performance to enable greater complexity and realism.
• Generalise and abstract existing models to allow re-use across different projects and geographies.
• Contribute to the full development lifecycle, including testing, documentation, security, and performance.

What We’re Looking For:

• Strong experience coding in modern C++ (or a comparable systems programming language such as Rust).
• Knowledge of low-level performance concepts such as SIMD, cache locality, and memory access patterns.
• Python for scripting and prototyping.
• Experience with agent-based modelling or entity-component-system (ECS) frameworks.
• Background in writing production-quality code and scaling models to work with very large datasets.
• Knowledge of distributed systems and data engineering (Kafka, pipelines, metadata management).
• Experience with containerised deployments (Docker, Kubernetes, Helm).
• Strong collaboration skills, with a focus on sharing knowledge and working as part of a team.
• A holistic approach to software engineering that considers testing, documentation, performance, and security.

This is an opportunity to work on high-impact projects where technology directly supports better decision-making in complex, real-world environments.
