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.
