Senior Java Developer

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.
