Enterprise Architect – Standards, Process and Tooling

Role Overview

• Ensure that architecture standards are defined, communicated and enforced.
• That the enterprise repository is governed and exploited to maximum effect, and that modelling practice using Archimate and BizzDesign Horizzon is consistent, high quality, and aligned to wider governance frameworks.
• Own and maintain Leonardo UKs EA standards and framework, including architecture principles, modelling conventions, pattern library, and governance ruleset.
• Develop publish and communicate architecture standards documentation, ensuring accessibility for both practitioner and non-practitioner audiences.
• Manage the lifecycle of architecture principles – creation, ratification, periodic review, amendment and retirement – through appropriate governance channels.
• Establish and enforce Leonardo UKs ArchiMate modelling conventions guide, covering maintaining Leonardo UKs metamodel, element usage, relationship types, naming conventions and viewpoint selection criteria.
• Develop and maintain an architecture pattern library within BizzDesign Horizzon, covering approved patterns across relevant domains (infrastructure, application, security, data, integration).
• Provide authoritative guidance to architects and project teams on the correct application of standards, resolving ambiguity and escalating gaps or conflicts as appropriate.
• Act as system administrator and governance owner for the BizzDesign Horizzon enterprise architecture repository.
• Design, implement, and maintain the repository taxonomy, including model structure, element classification, relationship categorisation and view organisation.
• Establish and enforce repository governance policies covering naming conventions, version control, model ownership, access permissions, and archiving.
• Maintain the currency and accuracy of baseline architecture content, co-ordinating with domain owners to ensure landscape models reflect the current state of the enterprise.
• Maintain integration between the Horizzon repository and related tooling, including ITSM linkage (ServiceNow), and reporting outputs.

Requirements

• EA Tooling: Deep, hands-on administrative and operational experience with Bizzdesign Horizzon (including Enterprise Studio, Horizzon portals, and scripting/querying features).
• Modelling Notations: Advanced proficiency and certification in ArchiMate (experience with TOGAF is highly desirable).
• Metamodel Design: Proven capability in creating and tailoring architecture metamodels to fit complex organisational structures without breaking standard compliance.
• Data Integration: Experience linking EA repositories to CMDBs (e.g. ServiceNow) data catalogues, or API layers to drive data-driven architecture.
• Experience: Minimum of 5+ years working within an Enterprise Architecture function, with at least 2-3 years explicitly focused on EA tooling, repository management, and governance.
• Experience working in highly regulated or defence/aerospace industries.
• Process Governance: Strong track record of defining governance workflows, architecture boards, and compliance checkpoints that enable speed rather than causing bottlenecks.
• Communication: Exceptional ability to translate technical architectures and modelling data into clean, business friendly viewpoints and reports.
• Influence & Coaching: Strong peer-leadership skills to guide and influence a diverse community of architects toward a unified way of modelling.
