Sr. Java Developer

Responsibilities

Technical Development:

• Develop and maintain scalable, robust, and high-quality Java applications for enterprise-level systems.
• Build microservices using Spring Boot and ensure seamless integration with other services.
• Write efficient back-end services using Java frameworks such as Hibernate and implement RESTful APIs.
• Collaborate with front-end developers to design responsive and interactive user interfaces.
• Integrate third-party APIs and external services into the existing architecture.
• Participate in software architecture discussions to create well-structured and modular applications.
• Continuously learn and adapt to new technologies to ensure solutions remain cutting-edge.

Code Writing in Java Technology:

• Core Java Principles:
  Leverage Javas object-oriented programming (OOP) concepts—inheritance, encapsulation, polymorphism, and abstraction—to design modular, reusable, and maintainable code.
• Implement robust error handling mechanisms using custom exceptions, try-catch blocks, and finally clauses, ensuring resilience to unexpected failures.
• Utilize Java’s Collections framework for data manipulation, including advanced usage of lists, sets, maps, and concurrent collections for multi-threaded environments.
• Advanced Java Practices:
  Use Java 8+ features such as Lambda Expressions, Streams API, and Optional classes for concise and expressive code.
• Develop multi-threaded applications using Java’s concurrency utilities like Executors and Completable Futures.
• Implement asynchronous processing to ensure high performance and scalability.
• Frameworks and APIs:
  Develop enterprise-grade applications using Spring Boot, Hibernate, and JPA.
  Implement robust RESTful APIs and integrate with SOAP-based services when necessary.
  Ensure seamless database interactions and optimize ORM configurations for performance.

Code Quality and Optimization:

• Follow clean coding standards, including naming conventions, modular design, and consistent formatting.
• Conduct comprehensive code reviews to ensure adherence to best practices.
• Implement automated testing frameworks such as JUnit or TestNG for unit testing and Mockito for mocking.
• Optimize application performance by profiling and resolving bottlenecks using tools like VisualVM or YourKit.
• Write secure code following OWASP guidelines to mitigate risks like SQL injection and cross-site scripting (XSS).
• Refactor legacy codebases to improve readability, modularity, and maintainability.
• Ensure integration with CI/CD pipelines using tools like Jenkins or GitHub Actions for smooth deployments.

Collaboration:

• Work closely with cross-functional teams to gather and understand technical requirements.
• Collaborate with front-end teams to ensure seamless integration of user interfaces with back-end services.
• Partner with Quality Assurance (QA) teams to deliver a reliable, high-quality application.

Project Ownership:

• Take ownership of assigned tasks and ensure timely delivery of high-quality solutions.
• Contribute to the full software development lifecycle (SDLC), from design to deployment.
• Maintain technical documentation and participate in knowledge-sharing activities within the team.

Required Skills and Qualifications:

• Proficient in Java, Spring Boot, Hibernate, and MVC frameworks.
• 4 to 6 years of experience in designing and developing scalable applications.
• Experience with microservices architecture and RESTful APIs.
• Strong understanding of version control tools (e.g., Git) and task management tools (e.g., JIRA).
• Hands-on experience with CI/CD practices and tools like Jenkins.
• Familiarity with cloud platforms such as AWS or Azure.
