Senior Java Developer – Spring Boot | TDD | CI/CD | AWS

Senior Java Developer – Spring Boot, REST APIs, TDD & CI/CD

Roles and Responsibilities:

• Design, develop, and maintain high-quality, maintainable Java applications and services 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) and continuous testing practices to drive design, maximize coverage, and prevent regressions.

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

• Embed security-by-design throughout the development life cycle, following secure coding standards and addressing vulnerabilities early.

• 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, security scanning, 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.

• 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, security, and reliability issues.

• Stay current with emerging technologies, including AI-assisted development and developer experience platforms, and evaluate how they can improve quality and productivity.

Skills Required:

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

• Experience with modern UI technologies (for example, React, Angular, TypeScript, JavaScript, HTML5, CSS) is preferred.

• 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.

• Working knowledge of secure coding practices and application security fundamentals (for example, the OWASP Top 10).

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

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

• Experience with build tools such as Maven or Gradle and source code management tools such as Git and Bitbucket.

• Experience integrating automated tests, quality checks, and security gates 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 working with AI agents or agentic development workflows.

• Experience with backend API technologies such as Node.js is preferred.

• Experience with Backstage and related developer portal technologies.

• Experience building and maintaining CI/CD pipelines and related tooling.

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

• Experience with cloud platforms such as AWS.

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

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