Job description
Beeline ID
120976-1
Assignment Duration
12 Months
Total Yrs. of Experience
8+ 10 years
Detailed JD (Roles and Responsibilities)
We are looking for a Senior Full-Stack Engineer who is having relevant experience of 8 years in end-to-end across a modern React.js frontend and a Spring Boot microservices backend. You'll design and build resilient APIs, craft accessible and performant user interfaces, and collaborate with cross-functional teams to ship customer-centric experiences at speed and scale.
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, OAuth2/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 PR 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).
Grahl (Apollo/federation) or TRPC. Messaging (Kafka), caching (Redis), and Kubernetes production experience. open API first development; API gateways. Security tooling (SAST/DAST, OWASP Top 10) and secrets management. Performance profiling (Lighthouse, Chrome Dev Tools, JFR, JMC) and Core Web Vitals ownership. Feature flagging (Launch Darkly/Unleash), analytics (GA4/Segment). Domain exposure: [Your Domain-FinTech/Telecom/Healthcare/etc.].
