Please note that unless you are an existing member of staff at Justice Digital, Data and Science, the only London location being recruited to is 10 South Colonnade, E14 4PU. We are no longer recruiting to 102 Petty France, SW1H 9AJ.

The Role

We’re recruiting for a Senior WordPress/PHP Developer here at Justice Digital, Data and Science to be part of our warm and collaborative Website Builder Platform Team.

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.

You’ll be confident working with other developers on our tech stack and comfortable learning new technologies and systems. We use a variety of different technologies and will work with you to place you in a team that matches your skills, interests, and aspirations wherever possible.

We take responsibility for supportive and effective line management very seriously. We will value the skills you bring to the civil service and help you build on them. When the time is right, we will support moving between teams or government departments to learn different technologies, or take on more responsibility, according to your career goals.

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.

Benefits

• 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!
