Lead Business Architect

As a Lead Business Architect within the Chief Technology Office (CTO), you will work at the centre of the Home Office’s digital and technology strategy, shaping how enterprise architecture is designed, governed and evolved across the department. The CTO sets the strategic direction for technology, establishes standards, ensures coherent design, and enables major programmes to deliver secure, modern and user-centred services.

In this hands‑on, flexible role, you will translate business needs into clear architectural insight, support enterprise‑wide decision making, and work closely with architects, engineers and senior leaders across technology, strategy and design.

You will lead and shape business architecture activities across the Architecture function, covering governance, technology debt management, architecture tooling, and cross‑cutting discovery and design, while creating integrated artefacts such as capability models, value streams and operating models that align strategic intent with day‑to‑day operations and technology roadmaps.

Drawing on frameworks such as Biz Bok, you will anticipate emerging challenges, set direction for major transformation initiatives, maintain strong links with other architecture professions and cross‑government architecture communities, and ensure the technology landscape is insight‑driven, well‑governed and aligned to strategic priorities, enabling informed, coherent decisions that support secure, efficient and high‑quality public service delivery.
