The foundational work on GBE’s security standards and core technology is already underway, with every significant decision and its reasoning recorded so that the incoming postholder can review, confirm and own those decisions rather than start from a blank page. The budget and the mandate to build a small architecture team are in place. Few roles offer the chance to set the technology direction of a national institution this early in its life.Key Responsibilities:* Take ownership of the architecture decisions made during the establishment phase: review the recorded decision log, confirm or adjust the recommendations against the evidence, and carry them into delivery.* Land GBE’s foundational technology choices — cloud, GBE’s own productivity and collaboration environment, and staff identity and access — and lead the design of the move away from shared, inherited services.* Stand up the Architecture Review Board and Technical Design Authority as working design authorities, with a proportionate, fast assurance route into investment decisions.* Publish the first full set of architecture principles, standards and

govern and personally deliver key parts of GBE’s platform.* A senior enterprise or chief architect with a track record in complex, fast‑moving organisations, including building an architecture function or practice from the ground up.* Real delivery behind the architecture: target‑state designs that became working platforms, spanning cloud environments, modern workplace and collaboration estates, identity and access, integration, and core business systems such as ERP and CRM.* Experience running design authority governance — chairing architecture review boards or equivalent, and assuring major designs and investment proposals — in a way that accelerates delivery rather than slowing it down.* Strong commercial perspective, including whole-life value, reuse, interoperability, sustainability, sourcing choices and supplier assurance.* Expert ability to architect for the whole organisational context, frame high-complexity problems, make high-risk architectural decisions and connect strategy across organisational boundaries.* Depth in cloud strategy: shaping provider selection and multi‑year cloud economics, and designing to keep options open and avoid lock‑in.* Practical experience architecting for data and AI, including patterns for the responsible, governed adoption of AI in a business.* Experience of complex sourcing environments: setting the standards for, and assuring, work delivered through multiple partners and framework agreements.* The communication skills and credibility to make architecture clear and compelling to executives, boards and non‑technical decision makers.* Comfort operating where structures, processes and ways of working are still being established, with the pragmatism to make sound decisions at pace with imperfect information.Desirable:* Experience in the energy, renewables, utilities or infrastructure sectors, or other asset‑intensive industries, with an understanding of how technology enables investment, project delivery and operational performance.* Experience in government or other high‑assurance settings, including working to Government Digital Service standards and National Cyber Security Centre
