Senior Java Software Engineer

About the role:

Brainsquare India is expanding its Java team with senior engineers who will work on API-driven back-end development using Spring Boot.
You’ll focus on project delivery, new feature development, and technical excellence - not routine maintenance.
In this role, you’ll act as a technical reference for your peers, ensure code quality, and help shape development standards within our teams.

Key Responsibilities:

• Design, develop and extend REST APIs using Java 11 / 17 and Spring Boot.

• Translate complex requirements into modular, testable code.

• Create and maintain unit and integration tests to guarantee quality.

• Conduct code reviews, enforce coding standards, and mentor junior developers.

• Contribute to project delivery in an agile environment with cross-functional teams.

• Ensure secure coding practices (OWASP Top 10 / Spring Security).

• Collaborate with DevOps teams on CI/CD integration and deployment automation.
