Senior Java Developer - TDD, JUnit, CI/CD & Code Quality

Senior Java Developer  – TDD, JUnit, CI/CD & Code Quality

Roles and Responsibilities:

• Design, develop, and   maintain high-quality, maintainable Java applications   using clean code   principles and established   design patterns.

• Write comprehensive,   meaningful unit tests   using JUnit and   Mockito to ensure   code correctness, reliability, and long-term   maintainability.

• Apply test-driven   development (TDD) practices   to drive design, maximize coverage, and   prevent regressions.

• Champion code quality   through thorough code   reviews, pair programming, and adherence to   coding standards and   best practices.

• Refactor and improve   existing codebases to   reduce technical debt   and enhance readability, performance, and testability.

• Apply core Java   concepts—collections, concurrency   and multithreading, generics, streams, exception handling, and JVM memory   management—to build   robust solutions.

• Integrate automated unit   testing, static code   analysis, and quality   gates into CI/CD pipelines.

• Use tools such   as SonarQube and   JaCoCo to measure, enforce, and continuously   improve code quality   and test coverage.

• Build modular, reusable, and testable applications   and APIs (REST   web services) in   Java.

• Collaborate with architects, business and application   analysts, operations teams, and testing specialists   to deliver reliable, secure, high-quality   solutions.

• Diagnose, troubleshoot, and resolve complex   technical, performance,   and reliability issues.

• Ensure information security   standards and requirements   are incorporated into   all solutions.

• Stay current with   emerging technologies,   including AI-assisted   development and automated   test generation, and   evaluate how they   can improve quality   and productivity.

Skills Required:

• 5+ years of   software development experience   in Java, spanning   the full application   development life cycle.

• Strong command of   core Java concepts, including collections,   concurrency/multithreading, generics,   streams, lambdas, exception   handling, and JVM   memory management.

• Proven, hands-on   experience writing effective   unit tests with   JUnit and mocking   frameworks such as   Mockito.

• Solid understanding of   test-driven development  (TDD), test automation, and continuous testing   practices.

• Deep commitment to   code quality, clean   code, SOLID principles, and design patterns.

• Experience with   static code analysis   and code coverage   tools such as   SonarQube and JaCoCo.

• Experience building RESTful   APIs and microservices   using frameworks such   as Spring / Spring   Boot.

• Experience with build   tools such as   Maven or Gradle.

• Experience with source   code management tools   such as Git   and Bitbucket.

• Experience integrating   automated tests and   quality checks into   CI/CD pipelines  (for example,   Jenkins).

• Strong analytical, problem-solving, communication,   and technical documentation   skills.

• Ability to work   effectively in a   fast-paced, cross-functional Agile environment.

Nice to Have  (Added Advantage):

• Experience   using AI-assisted   development tools (for   example, GitHub Copilot) to accelerate coding   and testing.

• Experience with AI-powered or automated   unit test generation   frameworks (for example, Diffblue Cover, EvoSuite, or similar) is a strong   added advantage.

• Experience with integration, performance, and contract   testing tools.

• Experience with containerization   and orchestration technologies   such as Docker   and Kubernetes.

• Experience with cloud   platforms such as   AWS.

• Knowledge of security   scanning tools such   as SonarQube, JFrog   Xray, or similar.

• Experience with Jira, Confluence, and Agile   delivery practices.

•  University Degree or   College Diploma in   Computer Science or   a related technology   field.

• Knowledge of the   financial and insurance   industries.
