ROLES AND RESPONSIBILITIES
As a Full Stack Developer, you will design, build and operate modern, secure, cloud-native applications on Microsoft Azure. The role focuses on either Java backend development or React frontend development as the primary discipline, with strength in both considered a strong advantage. You will work end-to-end across the stack — translating business requirements into reliable, scalable and performant solutions — while collaborating closely with Business Analysts, architects and cross-functional engineering teams. You will uphold coding standards, contribute to CI/CD practices, and guide the team through reviews, testing and engineering best practices.

Key Responsibilities:

2. Design and develop scalable, high-performance backend services using Java, Spring, Spring Boot, and Spring Batch (where applicable to the role).

3. Implement RESTful Web Services and microservices architectures that enable seamless communication and data flow between front-end and back-end components.

4. Build accessible, performant and maintainable user interfaces using ReactJS (and NextJS / Angular where applicable), with strong attention to component reusability and design system alignment.

5. Leverage Microsoft Azure services (e.g., App Service, Azure Functions, AKS, Azure SQL, Storage, Key Vault) to deliver secure, scalable and cost-effective solutions.

6. Apply containerisation and orchestration practices using Docker and Kubernetes (AKS) to enhance deployment efficiency and scalability.

7. Review requirements and user stories for technical feasibility, scope and risk — propose pragmatic alternatives when needed.

8. Investigate issues, perform root-cause analysis, and implement resilient fixes with appropriate test coverage.

9. Write clean, testable code with unit and integration tests; ensure accessibility (WCAG), performance and security best practices are met.

10. Participate in code reviews, maintain coding standards, and contribute to the shared component library and reusable backend modules.

11. Partner with Business Analysts to clarify edge cases and ensure business value is met.

12. Contribute to backlog grooming, daily stand-ups, and retrospectives in an Agile environment; provide accurate estimates.

13. Collaborate on CI/CD pipelines, feature flags and observability to enable safe, frequent releases.

14. Stay current with emerging trends in backend, frontend, cloud-native development and Azure services to drive continuous improvement.
