• Design and develop backend services using Java, Spring Boot, and related frameworks.
• Write clean, modular, and testable code following best practices.
• Participate in technical design discussions and peer reviews.
• Contribute to the evolution of our microservices architecture.
• Implement and maintain unit and integration tests (e.g., using JUnit, Postman).
• Contribute to CI/CD pipelines and ensure code is production-ready.
• Collaborate with QA to support functional and end-to-end test coverage.
• Work closely with product managers, senior engineers, and designers to translate requirements into technical deliverables.
• Participate in Agile ceremonies including sprint planning, retrospectives, and demos.
• Provide accurate effort estimates and deliver to sprint commitments.
• 5+ years of experience in backend development, primarily using Java and Spring Boot.
• Strong understanding of RESTful APIs, microservices, and design principles.
• Experience with version control (Git), build tools (e.g., Maven/Gradle), and CI/CD workflows.
• Exposure to Agile development and testing frameworks like JUnit or Postman.
• Good problem-solving and debugging skills.

Good to Have

• Familiarity with Kotlin or willingness to learn.
• Exposure to frontend technologies (e.g., basic React or Angular).
• Experience with containerization tools like Docker.
• Awareness of cloud platforms such as AWS or GCP.
• Understanding of secure development and performance tuning.
