The Role

Please note this role requires you to pass Security Check clearance. Please click on the link for details.

We’re recruiting for Senior Integration Architects here at Justice Digital, Data and Science, to join the Office of the Chief Technology Officer (OCTO), working within the Chief Architect function and within the Integration team. You will play a key role in shaping and delivering integration architecture across our landscape, helping ensure that services and data can be connected securely, reliably and consistently 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.

We are establishing a new integration hub to enable more consistent, reusable and governed approaches to how systems interact across the MoJ estate. This will play a key role in reducing point-to-point integrations, improving interoperability, and enabling services to evolve more independently.

As a Senior Integration Architect, you will contribute to the design and evolution of the integration hub and the wider integration ecosystem. You will apply and promote established integration patterns and standards (such as APIs, events and messaging), supporting teams to design and deliver integrations that are robust, reusable and aligned to organisational strategy.

You will work closely with delivery teams, product teams, platform teams and other architects to design integrations between systems, helping to reduce duplication, improve reuse and ensure services remain loosely coupled but well connected. You will contribute to architectural decisions and support the consistent adoption of integration approaches across services.

You will support integration both within the Ministry of Justice and, where needed, across the wider Criminal Justice System, working with partners to enable effective interoperability between systems and services.

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 Senior technical architect role from the Government Digital and Data Framework.

You’ll receive a range of excellent benefits when you join our department, including:

  • A generous employer pension contribution of 28.97% through the Civil Service Pension Scheme.
  • 25 days of annual leave, (increasing to 30 days once you have reached 5 years of service), plus 8 bank holidays and a privilege day for the King’s birthday.
  • Flexible working arrangements including hybrid working, working part time or compressed hours. Designed to support a positive work–life balance.
  • Employees are allocated 10% of their working time for personal and professional development.
  • A £1k per person learning budget is in place to support all our people, with access to best-in-class conferences and seminars, accreditation with professional bodies, fully funded vocational programmes and e-learning platforms.
  • Compassionate maternity, adoption, and shared parental leave policies, with up to 26 weeks leave at full pay, 13 weeks with partial pay, and 13 weeks further leave. And maternity support/paternity leave at full pay for 2 weeks, too!

  • Apply and promote integration patterns and standards (including APIs, event-driven architecture and messaging), supporting teams to build consistent and interoperable services.
  • Work with teams across the organisation to design integrations that reduce point-to-point complexity and encourage reuse of shared capabilities.
  • Support integration across organisational boundaries, including within MoJ and, where needed, across the wider Criminal Justice System, collaborating with partner organisations.
  • Guide the design of integrations within delivery teams, helping ensure solutions are robust, loosely coupled and aligned to best practice.
  • Mentor and support other architects and engineers, contributing to the development of integration capability and the wider architecture community.
