  • Build and support back-end services using Spring Boot, Spring Framework, RESTful APIs, and microservices.
  • Develop and maintain APIs for application functionality, system integration, and communication between platforms.

  • Work with relational databases, SQL queries, data modeling, stored procedures, Hibernate/JPA, and database optimization.
  • Write clean, efficient, secure, and maintainable Java code.
  • Support unit testing, debugging, troubleshooting, performance tuning, and code optimization.
  • Contribute to technical design discussions, architecture reviews, and solution planning.
  • Collaborate with cross-functional teams, QA teams, business stakeholders, and project managers to deliver high-quality solutions.
  • Participate in code reviews and promote coding standards, documentation, and development best practices.
  • Guide junior developers when required and support team-level technical growth.
  • Use AI tools, automation practices, and emerging technologies where applicable to improve productivity and application capabilities.

What We're Looking For
  • 5 to 10 years of hands-on experience in Java application development, back-end development, or enterprise software development.
  • Strong hands-on experience in Java is mandatory.
