• Collaborating with Product Owners, Business Analysts, and Designers to translate requirements into well‑structured, user‑focused solutions
• Contributing to system design and architectural discussions, supporting the Tech Lead in defining technical approaches and implementation strategies
• Applying best practices in frontend engineering, including component‑based architectures, state management, and performance optimisation
• Ensuring high‑quality delivery through comprehensive testing across the stack, including unit, integration, and end‑to‑end testing
• Participating in code reviews to promote maintainability, performance, security, and usability.
• Supporting CI/CD pipelines, deployment processes, and continuous improvement initiatives, including reducing technical debt and enhancing engineering practices

Who we're looking for:

• Strong experience delivering full‑stack applications, with hands‑on development across both TypeScript‑based frontends and Java/Spring Boot backends
• Solid grasp of modern frontend architecture, including component‑based design, state management, and performance optimisation
• Proven ability to build and consume RESTful microservices and integrate frontend applications with backend services
• Practical experience working with AWS services and an understanding of distributed systems and cloud‑native architectures
• Strong knowledge of testing practices across the stack, covering unit, integration, and end‑to‑end testing
• Experience working with CI/CD pipelines and modern Agile development workflows such as Scrum or Kanban
• Good understanding of clean code principles (e.g., SOLID) and modern architectural patterns such as hexagonal or layered architecture
• Capability to debug complex issues across frontend and backend systems, performing effective root‑cause analysis and contributing to a high‑performing team culture

Whatever your role, we reward performance and behaviour with a package that looks after all the things that are important to you. Here are some of the benefits we offer:

• The opportunity to participate in our annual, performance -related bonus plan and valuable share schemes
• Generous pension contribution
• Life assurance
