About this role
Salary: £62,000 - 102,000 per year
Requirements: We need experience creating logical and physical data models and explaining them clearly to technical and non-technical audiencesWe need experience using UML modeling tools such as MagicDraw, PowerDesigner, or Eclipse-based toolingWe need experience applying metamodel concepts such as UML and MOF to structure and govern modeling approachesWe need experience working with controlled vocabularies and metadata standards to drive consistency and reuseWe need experience producing and interpreting mappings and lineage to explain how data is related, moved, and transformedWe need the ability to translate between models and their representations in programming and schema languages, including building or maintaining domain-specific languages and abstract syntax structuresWe need programming experience in one or more languages such as Java, JavaScript, Python, or C++We need experience implementing language tooling components such as parsers, interpreters, compilers, debuggers, or related frameworksWe need the ability to prototype solutions independently and navigate ambiguous design and functionality problemsWe need experience collaborating with business and technical teams to understand, translate, review, and playback requirementsWe need demonstrated experience designing metadata and language architecture that supports AI-enabled solutions, including enforceable semantics, lineage and provenance, and integration into scalable platforms with resiliency, security, and auditability requirementsPreferred: exposure to code generation patterns and the development or use of code generatorsPreferred: familiarity with data management technologies such as relational or columnar databases, data integration (ETL), or API developmentPreferred: familiarity with data formats such as JSON, XML, Avro, or Google Protocol BuffersPreferred: comfort engaging with the algorithms and mathematics behind languages, tooling, and data processingPreferred: academic background paired with hands-on implementation experiencePreferred: interest in how strong Information Architecture and models enable modern software development and engineering disciplinePreferred: awareness of how modeling and metadata practices support regulatory and control requirements Responsibilities: We will develop and maintain the metamodel to support current and emerging business needsWe will create and evolve metadata assets, including controlled vocabulary, mapping, lineage, transformation, and data content descriptionsWe will build and maintain mappings between metadata and software engineering assetsWe will design and maintain domain-specific languages that represent metadata, including their underlying structuresWe will prototype and maintain tooling that captures, integrates, validates, transforms, generates code from, reports on, and presents metadataWe will engage with customers, the Chief Data Office, product owners, Information Architects, development teams, and other stakeholders to communicate our Information Architecture vision and standards and support effective implementationWe will architect metadata and language foundations that enable AI solution capabilities, including semantic consistency, provenance and lineage, policy tagging, and interoperability across engineering workflowsWe will establish reuse-first, metadata-driven engineering patterns and governance that support AI-enabled platforms through well-defined models, DSLs, and tooling integrations Technologies: AIAPIArchitectETLEclipseSupportJSONJavaJavaScriptPythonSecurityUMLXMLCloud More:
