Job Description
Salary: £90,000 - 90,000 per year
Requirements:- We are looking for solid, practical experience in backend Java development and an interest in scalable distributed systems.

- We require experience developing cloud-native applications with a microservices architecture running on Docker, OpenShift, or Kubernetes.

- We are looking for awareness of AI coding assistants such as GitHub Copilot, Cursor, or Claude to accelerate development, generate boilerplate, and review code.
- We expect the ability to apply AI tooling critically by validating, refactoring, and integrating AI-generated code rather than accepting output uncritically.
- We value awareness of prompt engineering techniques relevant to software development workflows, including code generation, test writing, documentation, and debugging.
- We require experience working in an Agile/Scrum environment.
- We design, develop, and maintain backend components in Java with a focus on performance and resilience.

- We support releases, deployments, and production stability activities.
- We adhere to CI/CD pipelines, code quality standards, and operational readiness requirements.
- We apply performance, security, and resilience best practices, particularly around message handling.
- We work closely with the Technical Lead and peers to deliver against team objectives.
