Systems Engineer

Job description

At OMNIA Training, we’ve brought together some of the UK’s most innovative defence training organisations into a single consortium to delivery one powerful mission: to transform the British Army’s training system and create the best-trained Army in the world. OMNIA Training will redefine the British Army’s collective training, standing up as the Army’s Strategic Training Partner. To do that, we are looking for the best and brightest minds from across the UK.

We are backed by British innovation and powered by world-class experts, like you. OMNIA Training is primed by Raytheon UK, but all five partners (Raytheon, Rheinmetall, Capita, Skyral and Cervus) are key to delivering the scope of the contract. Supporting innovation, Rheinmetall Electronics UK (REUK) is entrusted with the trialling and acceptance of new products into the Army training system. This is more than a job — it’s a mission.

You will be part of a high-impact, collaborative environment, where we expect everyone to live the values and standards of the British Army. Every person in our team plays a critical role in delivering OMNIA Training’s vision; designing, delivering, and transforming collective training so the British Army is ready to fight and win. The Systems Engineer will be responsible for supporting the definition, integration, and implementation of system architectures that underpin complex Defence training systems and services.

Working in collaboration with the Enterprise Architect, you will help ensure that system design aligns with configuration management processes, data integration requirements, and broader architectural guidelines. This role involves engagement with system and data architecture, secure-by-design principles, configuration control, and planning for the migration of legacy data into the Defence Developer Services (D2S1) environment.

You will also contribute to governance forums, maintain system-level architecture artefacts, and ensure traceability across the system lifecycle. The role offers the opportunity to lead and shape the architectural direction of trial and test activities, working within advanced simulation and integration environments. You will collaborate closely with engineering, acquisition, and operational teams across Defence to ensure that new systems are validated, interoperable with legacy systems and aligned with strategic objectives.

Your contributions will be critical in ensuring operational readiness, enabling data-driven decision-making, and delivering secure, scalable, and integrated simulation training systems.
