Responsibilities

As an Architecture Modeller, your responsibilities will include:

• Developing, maintaining, and managing architecture artefacts across multiple domains (business, information, application, technology).
• Producing clear, consistent, and reusable models using recognised frameworks (e.g., MODAF, NAF, TOGAF).
• Supporting the definition of end-to-end architectures by creating architecture views, catalogues, and diagrams.
• Assisting Enterprise and Solution Architects in the assessment of supplier solutions against programme and enterprise standards.
• Mapping business requirements to architectural models, ensuring traceability across programme deliverables.
• Maintaining model repositories and ensuring consistency across architectural layers and suppliers.
• Contributing to technical governance by providing up-to-date and accurate models for design authorities and review boards.
• Supporting the development of roadmaps, technology options, and design decisions through high-quality modelling artefacts.
• Ensuring all modelling outputs are compliant with the MOD Common Architecture Approach (CAA) and relevant JSPs.
• Working with stakeholders to present models and explain complex architectures in a clear and accessible way.
• Supporting the integration of supplier models into a coherent enterprise-wide architecture baseline.

Experience

• Proven experience in architecture modelling in large-scale, high-security, or Defence/Government environments.
• Strong knowledge of MODAF/NAF or similar frameworks and the production of standard views and artefacts.
• Proficiency in architecture modelling tools (e.g., Sparx EA, MooD, System Architect, ArchiMate tools).
• Experience producing models across business, data, application, and technology domains.
• Understanding of Defence enterprise approaches such as the MOD Common Architecture Approach (CAA).
• Awareness of deployable and on-premise technologies in the Defence context.
• Experience supporting complex programmes with multiple suppliers and integration challenges.
• Knowledge of ISR/ISTAR capabilities, integrated sensor architecture (ISA), or related Defence systems advantageous.

Desirable Experience

• Prior experience working within the UK Defence sector or related government digital programmes.
• Familiarity with digital transformation projects including data, cloud, integration, and security aspects.
• Understanding of DLODs and Defence support models.
• Knowledge of tools and technologies such as APIs, KAFKA, VMWare, Systematic applications, and MongoDB desirable.
