About the role

ThePrincipal Data Platform Architectacts as the senior technical authority for the organisation’sdata platform technology landscape, accountable for defining, governing, and evolving the platforms that underpin Data Foundations, Data Products, analytics, and AI use cases at enterprise scale.

This role owns thestrategic and target‑state architectureof the data platform, including cloud data services, processing engines, integration and streaming technologies, and platform‑level capabilities such as security, resilience, scalability, and performance. Working closely with data engineering, data architecture, security, and platform operations teams, the Principal Data Platform Architect ensures that all Data & AI solutions are built on aconsistent, secure, and reusable platform architecturealigned to agreed enterprise standards and principles.

Operating at Principal level, the role balancesdeep technical leadershipwitharchitectural governance and assurance. Itis responsible forevaluating new data technologies, defining reference architectures and patterns, and guiding complex platform‑level decisions and trade‑offs across the organisation. The role plays a critical part in ensuring that platform evolution supports long‑term business value, cost efficiency, and operational sustainability, rather than short‑term project optimisation.

The Principal Data Platform Architect partners closely withEnterprise, Solution andData Architects, ensuring that platform decisions enable domain‑aligned Data Foundations and Value Pool delivery, without driving fragmentation or unnecessary divergence. While Solution Architects focus on end‑to‑end solution design for individual initiatives, this roleremainsfocused on theplatform as a product, ensuring coherence, scalability, and reuse across all delivery streams.

The role sits within the Data Architecture and Engineering teaminthe Data and AI Office.
