• Build and consume RESTful APIs and ensure seamless integration with frontend systems.
• Work closely with product managers, frontend engineers, and QA teams to deliver robust product features.
• Participate in the full software development life cycle — from requirement analysis and design to implementation and deployment.
• Write clean, maintainable, and testable code following best software development practices.
• Optimize application performance and ensure system scalability.
• Conduct code reviews, identify areas for improvement, and maintain code quality standards.
• Troubleshoot and resolve production issues, ensuring application reliability and stability.
• Collaborate with DevOps for CI/CD pipeline improvements and cloud deployments.
• Good to have: Contribute to frontend development using React.js when required and assist with integration between frontend and backend systems.

Qualifications:

• Bachelor’s degree in Computer Science, Information Technology, or a related field.
• 4–6 years of hands‑on experience in backend development using Java, Spring Boot, and related frameworks.
• Strong understanding of OOP principles, design patterns, and microservices architecture.
• Proficiency in working with REST APIs, JSON, and Web Services.
• Experience with databases (MySQL, PostgreSQL, MongoDB, or similar).
• Familiarity with build and dependency management tools (Maven, Gradle).
• Knowledge of version control systems like Git (GitHub/GitLab/Bitbucket).
• Experience with unit testing frameworks such as JUnit or TestNG.
• Understanding of cloud platforms (AWS, GCP, or Azure) and containerization (Docker/Kubernetes) is an advantage.
• Excellent analytical, debugging, and communication skills with a proactive attitude toward problem‑solving.
