About the job

Job summary

Here at the Ministry of Housing, Communities & Local Government (MHCLG), we work on things that make a real difference to people’s lives.

Whether it's through the homes we live in, the work of our local councils, or the communities we’re all part of, our work is at the top of the political agenda. We have ambitious and far-reaching outcomes to achieve this year and, if you’re thinking of joining us, there’s never been a more exciting time.  

We have over 3,500 staff who are based in 20 offices across the UK.  

The Data Migration Specialist is a critical role within the UNITY Programme. The UNITY Cluster is a cross-departmental UK government initiative involving HMRC, the Department for Transport (DfT), and MHCLG. Its goal is to modernise and unify back-office operations specifically finance, procurement, HR, and payroll - through a shared cloud-based ERP platform powered by SAP and delivered in partnership with Deloitte. The UNITY Cluster represents a significant digital transformation effort, impacting over 100,000 civil servants and aligning with the Shared Services Strategy. 

The successful candidate will be responsible for enabling seamless, secure, and accurate data transition across the organisation as part of a wider end-to-end transformation. We welcome candidates from a range of backgrounds—whether your experience lies in IT, data architecture, business analysis, or transformation. What matters most is your ability to work with complex datasets, understand business and user needs, and lead structured, risk-aware migration planning and execution. 

You’ll bring strong analytical skills, a detail-oriented mindset, and the ability to communicate technical concepts clearly to non-technical audiences. This is an exciting opportunity to contribute to a programme that is reimagining how data underpins decision-making, service delivery, and organisational performance. 

We particularly welcome candidates from an ethnic minority background and other underrepresented groups to apply, as we work to continually improve our ability to represent the places and communities we support through our work.
