Own and evolve the enterprise data modelling standard based on Data Vault 2.0, ensuring scalable, consistent and auditable design across the data platform.
Define architectural patterns that enable AI use cases at scale — including training data lineage, feature engineering, retrieval architectures and inference data flows — ensuring traceability from source data through to model output.
Set architectural standards for metadata, lineage, data contracts and interoperability that support both human and AI consumption of data.
Partner with AI Governance, Data Platform, Model Risk, Data Risk, Privacy and Security functions to ensure architectural decisions meet regulatory, ethical and risk requirements.
Act as design authority for data and AI-impacting design decisions; provide architectural review and assurance for major change initiatives.

Hands-on experience designing and implementing Data Vault 2.0 at enterprise scale.
Strong grasp of AI/ML data architecture: feature stores, vector stores, retrieval-augmented patterns and data flows for agentic systems.
Knowledge of how architecture supports regulatory and audit obligations in financial services (FCA, ICO, UK GDPR, NIST AI RMF, EU AI Act).
