About the Job
The Architecture Modeller will play a pivotal role in producing high-quality architectural artefacts and models, ensuring alignment with recognised frameworks, standards, and enterprise-level direction. Working within an established client-side team, you will collaborate with solution and enterprise architects, providing modelling expertise and supporting the technical assurance of supplier deliveries.
The ideal candidate will have strong skills in developing and maintaining architecture models (business, data, application, and technology layers) and industry frameworks. They will be comfortable operating in the Defence domain and in a complex multi-supplier environment.
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., 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 program and enterprise standards.
* Mapping business requirements to architectural models, ensuring traceability across program 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.
* 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 Government environments.
* Strong knowledge of NAF or similar frameworks and the production of standard views and artefacts.
* Proficiency in architecture modelling tools (e.g., Sparx EA, System Architect, ArchiMate tools).
* Experience producing models across business, data, application, and technology domains.
* 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.
Key Competencies
* Strong analytical and modelling skills with great attention to detail.
* Ability to explain complex architectures and modelling outputs clearly to both technical and non-technical audiences.
* Collaborative team player, able to work with Enterprise/Solution Architects, Engineers, and Programme Managers.
* Ability to maintain consistency, accuracy, and quality across large sets of models and artefacts.
* Proactive in identifying modelling improvements and ensuring alignment with enterprise frameworks.
