Description

Key Responsibilities
End to End Delivery
Own features across frontend (React TypeScript) and backend (Java Spring Boot) from design and implementation to testing, deployment, and observability. Translate business requirements into clean architecture, reusable components, and well documented APIs. Champion quality through code reviews, pair programming, and continuous improvement.

Frontend (React)

Build responsive, accessible SPA features with React 18 and TypeScript/JavaScript, using modern patterns (hooks, context, custom hooks). State management with Redux Toolkit or React Query; React Router for navigation. Forms & validation (React Hook Form, Yup/Zod), charts, and component libraries (MUI/Ant/Chakra). Styling with CSS Modules/SCSS/Tailwind; enforce standards via ESLINT/Prettier. Testing with Jest React Testing Library; E2E with Cypress/Playwright. Performance tuning (code-splitting, lazy loading, memoization, Core Web Vitals). Accessibility (WCAG 2.1 AA), internationalization (i18n) where applicable. (Optional) SSR/SSG using Next.js for SEO?sensitive surfaces.

Backend (Java/Spring)

Design and build RESTful microservices with Spring Boot, Spring Web, Spring Data JPA/Hibernate Secure services with Spring Security, OAut./OIDC, JWT; manage CORS/CSRF correctly for web clients. Define API contracts with OpenAPI/Swagger; ensure backward compatibility and versioning .Event-driven patterns (Kafka/RabbitMQ) and caching (Redis) as needed. Testing: JUnit 5, Mockito, Test containers for integration tests. MySQL, NoSQL (MongoDB/DynamoDB).

Performance profiling, SQL query optimization, resilience (timeouts, retries, circuit breakers).

DevOps & Platform.

CI/CD (GitHub Actions/Azure DevOps/Jenkins) for both frontend and backend pipelines (build, test, scan, deploy). Containerization with Docker, orchestration with Kubernetes (Helm as plus). Cloud deployment on AWS/Azure/GCP; IaC with Terraform is a plus. Observability: structured logging, distributed tracing (OpenTelemetry), metrics & dashboards (Prometheus/Grafana), alerts (ELK/EFK).

Collaboration

Work in Agile/Scrum; break down epics into deliverable increments, maintain technical documentation (API specs, ADRs).

Qualifications Must Have

6–10 years total experience with at least 5 years in Java (11/17 ) and Spring Boot.

2–4 years building production React applications; strong TypeScript/JavaScript proficiency.

Solid knowledge of HTML5/CSS3, responsive design, and web accessibility fundamentals.

REST API design; JSON; understanding of CORS, CSRF, and browser security. Proficient with Git (branching strategies), code reviews, and , workflows. Testing mindset: unit, integration, and E2E for both frontend and backend. Experience with Docker and a mainstream CI/CD tool. Strong problem?solving and communication skills.

Nice to Have

Next.js, Redux Toolkit, React Query, Storybook (design systems)
