Job Description - -------------- Job Description: **Key Responsibilities** * Design and develop microservices and backend components using Core Java and Spring Boot. * Develop, maintain, and version RESTful APIs; ensure adherence to API standards, contract-first design where applicable, and backward compatibility. * Implement API integrations with internal/external systems using REST/SOAP, webhooks, and third‑party services; handle authentication/authorization (e.g., OAuth2/JWT) as applicable. * Use Spring Boot ecosystem features (e.g., Spring MVC, Spring Validation, Spring Data/JDBC) to deliver clean and testable code. * Build resilient services with proper exception handling, retries/timeouts, circuit breaking patterns (as applicable), and structured logging. * Write efficient SQL queries and optimize data access (indexes, query plans) for performance and scalability. * Create API documentation (OpenAPI/Swagger) and maintain technical documentation for integration flows and operational support. * Write unit and integration tests; participate in code reviews and ensure high code quality and security best practices. * Collaborate with QA and DevOps on CI/CD, deployments, and production support; perform root cause analysis and implement preventive fixes. * Estimate tasks, manage deliverables, and contribute to sprint planning and agile ceremonies. **Must-Have Skills \& Qualifications** * 6 years of backend development experience with Java (Java 8 preferred). * Strong Core Java and JDK fundamentals: collections, concurrency, streams, I/O/NIO, exception handling, and JVM basics. * Hands-on experience with Spring Boot for building and deploying services (configuration, profiles, dependency injection, REST controllers). * Proven experience in API development and integration: REST principles, HTTP methods/status codes, pagination, idempotency, and error handling. * Strong SQL skills with experience in relational databases (e.g., PostgreSQL, MySQL, Oracle, SQL Server). * Experience with data access patterns (JDBC/Spring JDBC, JPA/Hibernate, MyBatis) and query optimization. * Familiarity with Git and collaborative development workflows (branching, pull requests, code reviews). * Understanding of secure API development: authentication/authorization, input validation, and OWASP-aware practices. * Strong problem-solving skills, communication, and ability to work across teams. * Experience with microservices patterns and components such as API Gateway, service discovery, and configuration management. * Knowledge of messaging and streaming (Kafka/RabbitMQ) and caching (Redis). * Build and automation tools: Maven/Gradle; CI/CD pipelines (Azure DevOps/Jenkins/GitHub Actions). * Containerization and orchestration: Docker and Kubernetes. * Observability tools (ELK/Splunk, Prometheus/Grafana) and performance testing exposure. **Key Competencies** * Ownership mindset and accountability for end-to-end delivery. * Ability to translate requirements into technical design and working software. * Attention to quality: testing, documentation, reliability, and maintainability. * Collaboration and stakeholder management in an Agile environment.
