Lead Business Architect

The Home Office works to build a safe, fair, and prosperous UK. We achieve this through our work on counter-terrorism, policing, crime, drugs policy, immigration, and passports.

The Migration and Borders Group (MBG) is responsible for the Migration and Borders System, issuing British passports, running the Civil Registration system, as well as managing Asylum, Protection, Resettlement and Integration services. Its mission is to deliver an efficient, effective and innovative Migration and Borders System that supports the needs of UK citizens and labour market and protects the security of the UK.

System Design sits at the heart of MBG and supports Ministers, the Executive Committee, Policy and Operational Leads. It owns and develops the MBG end-to-end Strategic Design and Business Architecture and facilitates a cross-cutting system approach to services, capabilities and interventions. If you join us, you will find a passionate and encouraging team, committed to the work and to supporting each other.

In this role, you’ll work at the intersection of business strategy and delivery, partnering with multidisciplinary teams to drive tangible outcomes that strengthen our public services and national security. You’ll draw on business architecture principles—e.g., capability mapping, value streams, and operating model design—to create a common language, enabling leaders and teams to spot gaps, opportunities, and interdependencies with ease. Whether you’re developing long-term strategies, supporting portfolio decisions for transformative digital initiatives, or facilitating knowledge sharing within the architecture and business design community, your input will shape how MBG functions at every level.

On a typical day, you could be translating high-level policy goals into actionable design artefacts for a new service, collaborating with other architects to keep transformation project and business change in sync, or coaching a junior colleague through best practices in knowledgebase interrogation and management. You’ll also have a hand in defining and maintaining the department’s architectural tooling, standards, and approaches —ensuring decisions are consistently well-informed, user-centred, and forward-looking. Ultimately, your ability to synthesize complexity, build consensus, and promote structured thinking will help deliver services that are more intuitive, integrated, and resilient – benefiting the public and advancing the Home Office’s overarching mission.

As a Lead Business Architect, you will collaborate across the entire Home Office to align strategy, transformation efforts and ongoing operations, ensuring our critical services keep citizens safe and the country secure. Whether advising on organisational design for complex processes, guiding portfolio and programme delivery, or supporting common standards and tooling, your role is both varied and impactful. You will use established frameworks (such as Bizbok) to facilitate structured problem-solving, intentional design, and data-driven decision making, cultivating a holistic view across departmental silos. Alongside a supportive architecture community, you will mentor others, share knowledge, and foster collaboration. If you thrive on tackling diverse, high-stakes challenges and enjoy shaping the bigger picture, this may be the perfect opportunity to leave your mark.
