About the Role
Design, build, and maintain end-to-end features spanning high-throughput Java backend services and modern web interfaces in a collaborative Agile environment. Take ownership of features from architectural design through implementation, testing, deployment, and monitoring.
Responsibilities
- Design, build, and maintain scalable Java-based backend services and modern frontend web applications.
- Develop robust RESTful APIs and integrate frontend interfaces seamlessly with backend systems.
- Build responsive, accessible, and performant user interfaces using modern web frameworks.
- Write clean, testable, and maintainable code across the full stack following engineering best practices.
- Collaborate with Product Managers, UX/UI Designers, QA, and platform teams to translate user requirements into technical solutions.
- Participate in peer code reviews, contribute to architectural discussions, and proactively address technical debt.
- Support deployment pipelines, troubleshoot production issues across frontend and backend layers, and drive continuous improvement.
Requirements
- 3–6 years of commercial full-stack software development experience.
- Strong backend expertise in Java, Spring Boot, and RESTful API design; gRPC experience is a plus.
- Hands-on frontend experience with modern JavaScript or TypeScript frameworks, preferably React. Commercial experience with Vue.js or Angular is also welcome.
- Proficiency in JavaScript, HTML5, CSS3/SCSS, and responsive UI design.
- Working knowledge of frontend build tools and package managers such as Vite, Webpack, npm, or yarn.
- Solid experience with relational databases such as MySQL, PostgreSQL, or Oracle, and SQL query writing.
- Strong understanding of OOP fundamentals, SOLID principles, and data structures and algorithms.
- Familiarity with testing frameworks across the stack, such as JUnit, Mockito, Jest, React Testing Library, or Cypress.
- Familiarity with Docker, Linux environments, and CI/CD pipelines.
- Exposure to microservices architecture.
- Awareness of secure coding practices including OWASP Top 10, XSS, CSRF prevention, and secure authentication/token management.
- Strong communication, analytical thinking, and collaboration skills.
- Experience with Java 17 and Spring WebFlux with Project Reactor, or Java 21+ Virtual Threads.
- Production experience with NoSQL systems such as DynamoDB.
- Production experience with TypeScript and modern frontend state management such as Redux Toolkit or Zustand.
- Familiarity with design systems, component libraries, and tools like Storybook or Figma.
- Production experience with microservices architecture, distributed caching with Redis, and event streaming with Kafka.
- Familiarity with container orchestration, Kubernetes, Helm, and cloud platforms such as AWS or GCP.
- Familiarity with observability and monitoring tools such as Prometheus, Grafana, OpenTelemetry, or Elastic Stack.
- Basic understanding of web accessibility and web performance optimisation.
