In this role, you will translate strategic data vision into tangible designs and solutions, ensuring data assets are secure, well-structured, and aligned with evolving Home Office priorities.

Partnering with Technical Architects, Principal Data Architects, and various data teams, you will evaluate existing platforms, identify gaps, and recommend optimisations whether via cloud-native services, large-scale distributed data platforms, or modern data warehouses.

You’ll oversee how data catalogues, metadata systems, and governance frameworks are implemented, championing best practices across multiple programs. By leading data design reviews, you’ll ensure alignment with department-wide standards, while also balancing performance, scalability, and compliance needs.

Additionally, you will serve as a trusted advisor to senior stakeholders, translating business requirements into actionable architecture patterns and reference models. You willcollaborate with and guide multiple stakeholders on data-centric initiatives in the Home Office. You’ll also mentor less-experienced data architects, sharing emerging trends in scalable data technologies and building a resilient, future-proof data estate.

Ultimately, your expertise will help streamline Home Office workflows, promote consistent data usage, and foster innovative ways to harness critical data at scale.
