Original job description

Job Title: Senior Java Engineer

Job Description:-

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.
