We’re looking Senior Full-Stack Developers to join a multi-year digital transformation programme modernising the future of offender management technology. With a strong pipeline of work over the next three years, this role offers the opportunity to help build the next generation of justice digital services—cloud-native, scalable, resilient, and designed for real-world impact.

The E-Supervision platform is a key part of the Ministry of Justice’s long-term strategy to modernise public safety and rehabilitation. By joining this programme, you’ll be helping to build more reliable and resilient digital systems that enable frontline staff to make better-informed decisions while improving the effectiveness of supervision for individuals on probation.

The work you deliver will streamline check‑ins, risk assessments and everyday supervision workflows, reducing the administrative burden on practitioners so they can focus more on people and less on manual processes. You’ll also play a vital role in replacing legacy systems, automating support processes, and introducing cloud-native, scalable services that significantly reduce operational overhead. The platform you help build will improve the quality and availability of real‑time data across the justice system, enhancing risk assessment, compliance tracking, and decision-making.

This is more than software development, it’s a chance to design and deliver technology that protects the public, supports rehabilitation, and strengthens the future of digital justice services for years to come.

What You’ll Be Doing

• Designing and developing secure, production‑ready software
• Building automated UI and API test frameworks
• Strengthening system reliability and reducing technical debt
• Improving support tooling and operational workflows
• Enhancing CI/CD pipelines and AWS infrastructure
• Working across frontend, backend, and cloud services
• Aligning with MoJ, GDS and HMPPS engineering standards

Who We’re Looking For

Communicative, proactive Senior Full-Stack Developers who enjoy modernising complex systems, improving engineering quality, and delivering mission‑critical services that genuinely help people.
