You will build and lead a team of talented data architects, work closely with engineers, analysts, and digital teams, and shape the future of how we design, govern, and manage data at the Ministry of Justice (MoJ).


This role sits within the newly established Chief Technology Office (CTO), which leads the Ministry’s technology strategy and delivery across prisons, agencies, probation services, and the MoJ corporate centre. The CTO works across the Chief Digital and Information Office (CDIO) to shape principles, processes, design patterns and roadmaps that underpin resilient, secure and cost-effective technology solutions. As part of this team, you’ll contribute to shaping a compelling 3-5 year vision, enable and support strategic and analytical initiatives for the Director of CDIO, and help model modern ways of working.
