Your Impact

Join Leonardo UK as an Enterprise Architect – Standards, Process and Tooling and play a pivotal role in maintaining the integrity, usability and maturity of the organisation’s architecture capability. The role sits at the intersection of technical architecture practice, tooling administration, and governance process design. This is not a project delivery role in the first instance, rather, the post holder will provide the practice infrastructure that enables other architects and project teams to operate effectively. The role carries significant responsibility for the quality and trustworthiness of architectural information across Leonardo UK.

The post holder will work closely with the Digital Solutions CTO UK, Digital Solutions CTO Italy, Head of Enterprise Architecture UK, Enterprise Architects, and Solution Architects, Domain Architects and Security Architects, as well as with technology governance bodies including the Global Architecture Board. They will represent the EA practice on standards-related workstreams and will be a recognised authority on modelling convention, tooling capability and repository governance.

We believe that high-impact architecture is driven by outcomes. This position operates on a highly flexible hybrid/remote working model. You will have autonomy to work predominantly remotely, with occasional, purposeful travel to the office for collaborative workshops, team alignment days, or critical stakeholder meetings.

This role reports to the Head of Enterprise Architecture UK and sits within the core EA practice team.

In this role you will

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.

Enterprise Architecture Standards and Principles

• 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.
• Contribute to the development of cross-cutting standards that align EA practice with other applicable frameworks.

Enterprise Repository Management

• 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.
• Manage user access, roles and permissions within Horizzon, maintaining appropriate separation of duties between model contributors, reviewers, and consumers.
• Implement model quality assurance processes, including validation rules, completeness checks and periodic model health reviews.
• 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.
• Produce and distribute regular Management Information from the repository, including architecture landscape summaries, coverage metrics, and risk registers.
• Maintain integration between the Horizzon repository and related tooling, including ITSM linkage (ServiceNow), and reporting outputs.

ArchiMate Modelling Framework

• Lead Leonardo UKs practice of ArchiMate modelling, acting as the primary subject matter expert for the modelling language and its application.
• Develop and maintain the ArchiMate modelling conventions guide, covering all three layers (Business, Application, Technology) and all five aspects (Active Structure, Passive Structure, Behaviour, Motivation, implementation & migration)
• Establish standard viewpoints for recurring architecture concerns, including capability maps, solution landscapes, application portfolio views, technology heat maps, and security overlay views.
• Conduct structured reviews of architecture models produced by project teams and peer architects, providing documented feedback and guidance on standards conformance.
• Develop and deliver modelling guidance, worked examples, and training materials to build ArchiMate capability across the architecture community.
• Maintain awareness of the ArchiMate specification and associated Open Group publications, incorporating updates and amendments into Leonardo Uks conventions as appropriate.

BizzDesign Horizzon Tooling Exploitation

• Maximise the exploitation of BizzDesign Horizzon across all available functional areas, including modelling, road mapping, regulation traceability, portfolio management and reporting.
• Develop reuseable BizzDesign templates, dashboards, custom views, and report configurations to support standard EA practice outputs and governance deliverables.
• Evaluate new BizzDesign produce releases, features and modules and make evidence-based recommendations to the Head o Enterprise Architecture regarding adoption.
• Manage the tooling roadmap for the EA practice toolset, identifying capability gaps, integration opportunities, and automation possibilities.
• Act as the primary point of contact with BizzDesign for licencing, support, and product engagement.
• Investigate, and where appropriate, implement integrations between Horizzon and related tooling, including ServiceNow and reporting platforms.

Process Governance and continuous improvement

• Design, document and maintain the EA practice’s operating processes, including the SAF, SAB and GAB submission processes, demand intake, architecture review, and model governance workflows.
• Establish and track EA practice metrics, including model coverage, standards conformance rates, SAB and GAB throughput, and repository health indicators.
• Drive continuous improvement of EA standards and tooling based on operational evidence, stakeholder feedback and industry benchmarking.
• Maintain the EA Practice’s process documentation library, ensuring all process artefacts are current, version controlled and accessible.
• Support the Head of Enterprise Architecture UK in producing strategy and roadmap content for the EA capability.

What You’ll Bring

• EA Tooling: Deep, hands-on administrative and operational experience with Bizzdesign Horizzon (including Enterprise Studio, Horizzon portals, and scripting/querying features). We are still keen to hear from you if you have hands-on administrative and operational experience of alterative EA tooling such as LeanIX, BizzDeisgn Alfabet etc.
• 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.

This is not an exhaustive list, and we are keen to hear from you even if you might not have experience in all the above. The most important skill is a good attitude and willingness to learn.
