Full Stack Developer

The Opportunity:

We are seeking a Full Stack Developer to join a live GOV-UK service environment in a hands-on role within an agile, autonomous delivery team.

You will contribute across both backend and frontend development, helping refine and evolve a live digital service where user impact and service reliability are paramount.

The role requires strong technical delivery capability, sound engineering judgement and the confidence to engage constructively with both technical and non-technical stakeholders.

This is not a maintenance-only position, you will play an active role in architectural discussions, continuous improvement and shaping the technical direction of the service.

Skills and Experience:

• Ruby on Rails
• Java (Spring Boot)
• AWS
• Experience deploying and managing serverless applications within AWS (Lambda and/or Fargate).
• Infrastructure as Code experience using Terraform.
• 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.

NB: The successful candidate will be required to undergo a basic level of security clearance before undertaking the assignment (two to four weeks lead-time).
