About the Role
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).
