About this role
Area(s) of responsibility
We are seeking a Java developer focused on building secure, scalable, and resilient RESTful APIs using Spring Boot . You’ll work closely with product managers, architects, and DevOps to deliver backend services powering web and mobile applications. The ideal candidate brings strong Java fundamentals, Spring ecosystem experience, and hands-on API design/implementation skills.
Key Responsibilities
- Design, build, and maintain RESTful APIs using Java and Spring Boot (Web, Data, Security, Actuator).
- Model and integrate with databases (SQL/NoSQL), write efficient queries, and manage schema migrations
- Implement API security : OAuth2/OIDC, JWT, role-based access, rate limiting, input validation.
- Write clean, testable code with unit, integration, and contract tests
- Optimize performance and reliability (caching, connection pooling, async/non-blocking I/O, pagination).
- Observability : structured logging (SLF4J/Logback), metrics/tracing (Micrometer, OpenTelemetry), and health checks (Actuator).
- CI/CD and cloud deployment (Docker, basic Kubernetes concepts, pipelines; Azure exposure a must).
- Collaborate in Agile teams : participate in grooming, estimation, code reviews, and documentation (OpenAPI/Swagger).
- Own services end‑to‑end : from design and development to deployment and production support (on-call rotation optional).
Required Qualifications
- Strong knowledge of Java 8+ (preferably 11/17 or later) and Spring Boot .
- Experience building RESTful APIs and integrating with external/internal services.
- Solid understanding of data structures, concurrency, and error handling .
- Hands-on with RDBMS (e.g., PostgreSQL/MySQL) and ORMs (JPA/Hibernate).
- Proficient with Git , branching strategies, and Maven/Gradle .
- Familiarity with API documentation (OpenAPI/Swagger) and Postman /Rest Assured.
Senior / Lead
- API architecture & design (resource modeling, versioning, idempotency, resilience patterns).
- Security best practices (OAuth2/OIDC, JWT, mTLS, secrets management).
- Scalability & resilience patterns (Circuit Breaker/Retry/Backoff with Resilience4j; async/reactive programming).
- Experience with microservices , message brokers (Kafka/RabbitMQ), and event-driven patterns.
- Cloud-native deployments (Docker/K8s) and IaC (Terraform/Helm is a plus).
- Mentoring developers and leading design/code reviews.
Education
- Bachelor’s in Computer Science/Engineering or equivalent practical experience.
