About The Job

Job summary

Across government, data architecture has become a critical capability in enabling organisations to unlock the value of their data, support informed decision making and deliver high-quality, joined-up services. As data ecosystems grow in scale and complexity, there is an increasing need for strong architectural leadership to ensure that data is structured, governed and integrated effectively. Modern data architecture is central to ensuring interoperability, enabling analytics and innovation, and supporting secure, resilient digital services.

At Ofgem, data is fundamental to delivering our mission to protect energy consumers and support the transition to a secure, affordable and sustainable energy system. As we continue to strengthen our Digital, Data and Security Services (DDSS) directorate, we are investing in our data architecture capability to ensure that data is consistent, accessible and aligned with organisational strategy. This will enable better insight, improved decision making and more effective delivery of regulatory and operational services.

As a Senior Data Architect , you will lead the design and implementation of data architectures across projects and programmes, ensuring alignment with Ofgem’s enterprise data strategy and standards. You will work closely with architects, engineers and business stakeholders to design scalable, interoperable and secure data solutions that meet both operational and analytical needs.

• Leading the design of conceptual, logical and physical data models, ensuring alignment with enterprise architecture principles and business needs
• Defining and promoting data standards, frameworks and best practices to ensure consistency, quality and compliance across data initiatives
• Designing data integration patterns that enable effective sharing, reuse and interoperability of data across systems and services
• Ensuring that data solutions meet security, privacy and quality requirements throughout the full data lifecycle
• Providing technical assurance for data solutions, ensuring alignment with governance, regulatory and architectural standards
• Collaborating with data architects, engineers, analysts and wider stakeholders to deliver effective and scalable data solutions
• Supporting the development of Ofgem’s data governance approach, including metadata management and master data practices
