• Solid working knowledge of PostgreSQL.
• Experience with Git, CI/CD pipelines and cloud-based development environments.
• Proven experience working within agile teams on live services, working closely with user-centred designers.
• Experience working within GDS/GOV-UK service standards would be ideal.

Role and Responsibilities:

• Build and maintain backend services using Java (Spring Boot) and PostgreSQL.
• Develop and enhance frontend functionality using Ruby on Rails and GOV-UK frontend.
• Contribute to architectural decisions and technical direction.
• Write clean, maintainable, well-tested code in line with modern engineering standards.
• Participate in code reviews, agile ceremonies and iterative delivery cycles.
• Ensure changes are assessed carefully for impact on live users.
• Support demonstrations and provide clear technical updates to clients and stakeholders.
• Collaborate with technical and non-technical stakeholders to refine and improve a live GOV-UK service.
• Working alongside user-centred designers to improve user experience.
• Engaging directly with clients and explaining technical concepts clearly.
