Modelling and Simulation Engineer

At Omnia Training, we’ve brought together some of the UK’s most innovative defence training organisations under one powerful mission: to transform the British Army’s training system and create the best-trained Army in the world.

Omnia Training is redefining the British Army’s collective training capabilities. To do that, we are looking for the best and brightest minds from across the UK. Omnia Training is at the heart of the UK’s bold Land Industrial Strategy.

This is more than a job — it’s a mission. You will be part of a high-impact, collaborative environment, where every person in our team plays a critical role in delivering Omnia Training’s vision; designing, delivering, and transforming collective training.

Please note that this role will require onsite working from our site in Warminster. Due to the nature of this role, Skyral can only consider applications from candidates who live in the UK and  are eligible for Government Security Clearance.

What You’ll Be Responsible For:

• Develop and adapt models based on customer-provided data, SME input and training needs.

• Implement behavioural logic, effects, interactions, and environmental responses in a way that is both representative and computationally efficient.

• Tune models to balance fidelity, performance, and scalability, making pragmatic trade-offs based on how the model will actually be used.

• Design models to be reusable and composable, contributing to a broader simulation ecosystem rather than one-off implementations.

• Ensure models behave coherently when composed with other models and systems, including handling timing, synchronisation, and interaction consistency.

• Integrate models with other simulation components, terrain, and environment systems, and external systems (e.g. via HLA, DIS, APIs).

• Working closely with our Simulation Integration Engineers, Simulation Content Engineer, and Quality Assurance Engineer.

• Take ownership of a primary modelling area (e.g. capability & effects, human behaviour, environment, or interoperability) while contributing across domains where required.

• Support iterative improvement based on validation outcomes, exercise feedback, and operational use.





Note: Please feel empowered to apply for this position, even if you think you may only align with some of the qualities listed above. Your unique skills and perspectives could be just what we’re looking for.

What We Are Looking For:

This is not a research modelling role. You will build models that are used in real training systems, where performance, integration, and usability matter as much as correctness.

• Strong analytical and systems thinking mindset.

• Comfortable working across multiple modelling domains.

• Curious and willing to challenge assumptions.

• Balances realism with practical constraints such as performance, fidelity and scalability.

• Comfortable iterating based on feedback , imperfect data, and evolving requirements..

Key Technical Proficiencies:

• Strong programming in high-performance C++ and Python.

• Experience building real-time systems and simulation components or engines.

• A strong understanding of modelling approaches including: Agent based modelling, Behavioural modelling, CNI modelling and physics/effects modelling.

• Experience with model calibration and tuning, representational fidelity and real-time simulation constraints.

• Experience working with real-time 3D simulation and visualisation platforms such as Unity and Unreal Engine.

• Experience designing models that can be reused and composed as part of a wider system, not built in isolation.

• Experience in one or more of the following: military capability modelling, human behaviour modelling, environmental modelling, terrain / GIS systems.
