Systems Engineering Lead in Bristol

At OMNIA Training, we’ve brought together some of the UK’s most innovative defence training organisations into a single consortium to deliver 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.

The Systems Engineering Lead spearheads the systems engineering function for one of the UK's flagship Defence programmes, delivered on behalf of the British Army, bringing together synthetic and live training solutions into a single, integrated capability. You will lead a small, specialist systems engineering capability at the core of the programme, acting as the senior technical authority and lead practitioner across the full engineering lifecycle — combining technical direction‑setting with hands‑on delivery of complex engineering work.

We are looking for a senior specialist with deep expertise in full‑lifecycle systems engineering on complex Defence platforms, suited to candidates at Senior or Principal level. While the programme is firmly rooted in the Land Domain, we welcome candidates with backgrounds in Sea or Air, particularly in Command and Control, Communications, or other complex, integrated technology platforms. You will bring depth of systems engineering expertise, the ability to set technical direction and uphold engineering standards, and a track record of delivering at programme scale in Defence.

The role is accountable for the integration and implementation of the system architectures underpinning complex Defence training systems and services. You will personally lead systems integration, verification, and acceptance activity, embed secure‑by‑design principles, govern configuration control, and direct the migration of legacy data into the Defence Developer Services (D2S1) environment. As the senior systems engineering authority on the programme, you will chair governance forums, own system‑level engineering artefacts, and assure traceability and technical integrity across the full system lifecycle, working closely with engineering, acquisition, and operational teams across Defence to bring new capabilities through to in‑service use.

The role can be based from Rheinmetall's offices in either Warminster or Bristol, with the latter requiring regular business travel to OMNIA's offices based in Warminster.

• Degree in Systems Engineering, Engineering, Defence Technology, or a related discipline.
• Proven experience as a Senior or Principal Systems Engineer or in a related role within Defence, government, or other complex or regulated environments.
• Strong understanding of system integration, configuration management, and data handling in secure, complex systems.
• Experience with Model‑Based Systems Engineering (MBSE) tools and architecture notations such as SysML or ArchiMate.
• Demonstrated experience in requirements analysis, traceability, and lifecycle support, including verification and validation activities.
• Experience with data integration and migration, including working with Government‑Furnished Information (GFI) or equivalent third‑party data sources.
• Understanding of data governance, data quality management, and Extract, Transform, Load (ETL) processes as part of system integration.
• Familiarity with Secure‑by‑Design principles, accreditation processes (e.g., RMADS), and cybersecurity standards applicable to Defence or secure systems.
• Strong communication and technical stakeholder engagement skills, with the ability to contribute to design reviews, governance boards, and cross‑functional planning.

• Experience working with MOD or Army platforms, systems, or data environments (e.g., D2S, Army Data Warehouse).
• Understanding of through‑life system support, including Integrated Logistics Support (ILS), RAM (Reliability, Availability, Maintainability) targets, and supportability engineering.
• Exposure to DevSecOps practices, including CI/CD pipelines and Infrastructure as Code (IaC) in secure environments.
• Awareness of safety and environmental assurance principles, including ALARP (As Low As Reasonably Practicable).
• Experience contributing to technical assurance, system readiness, and integration trials in simulation or mission‑critical domains.
