The Role
We’re recruiting for a Principal Technical Architect here at Justice Digital, to join the Office of the Chief Technology Officer (OCTO), working within the Chief Architect function and under the Chief Data Architect. You will provide technical architectural leadership across our data platforms, integration services and shared data capabilities, helping ensure that data can be shared securely, reliably and appropriately across the Ministry of Justice.
OCTO sets technical direction across the organisation. It defines standards, shapes shared platforms and ways of working and supports teams to build and operate systems that are secure, reliable and sustainable.
Justice Digital’s data capabilities are undergoing significant transformation as part of the MoJ Data Strategy. This includes:
• The evolution of the Justice Data Platform
• Adoption of Data as a Product and federated data ownership
• Strengthening data integration patterns across services and domains
• Improving governance, security and operational maturity across the data estate
As a Principal Technical Architect, you will ensure that the technical architecture for data and integration is coherent, scalable and aligned to wider Justice Digital strategy, enabling teams to publish, integrate and consume data safely and consistently.
We are a flexible organisation, and we understand that people can't always work 5 days a week or might have responsibilities that sometimes clash with standard office hours. We work as flexibly as we can, including offering part time hours, so if in doubt please do get in touch. If you're the right candidate we will do our best to work around you.
This role aligns against the Principal technical architect role from the Government Digital and Data Framework.
