This role is aligned with the specification of Senior Developer from the Government Digital and Data Framework 

We currently have over 200 experienced developers who make up the engineering community across the MoJ. You will coach and mentor junior colleagues and take part in informal support networks with your peers. You will be encouraged to play an active role in the engineering community and culture.

Our Tech Stack 

We use a range of technologies and we’re looking for people who have experience of building web applications or back-end systems in an object-oriented language, and love learning new languages and frameworks.   

We use WordPress/PHP and React JS to write our application code, GitHub Actions for CI/CD, Sentry for application monitoring, Kubernetes and Docker to schedule and run our services (read about our Cloud Platform), AWS for most of our infrastructure and use a MacOS developer environment. 

For front-end development, we value a robust understanding of the underlying web technologies. We value well-maintained, open-source tools that can be used to produce semantic HTML, performant CSS and unobtrusive JavaScript and we assess all our services against accessibility criteria. 

Check out GitHub for a closer look at the technologies we use, and a complete list of services that we build and maintain. We subscribe to the manifesto for agile software development.
