The ideal candidate will bring deep expertise in Java technologies, concurrency, and multi-threading, along with strong experience in ORM frameworks and asynchronous messaging. This role offers the opportunity to work in an agile environment, collaborate with cross-functional teams, and contribute to the continuous improvement of our API infrastructure, ensuring robust, secure, and efficient backend services.
Responsibilities
- Design, develop, and maintain scalable and secure RESTful APIs using Java, Spring Framework, and *Spring Boot to support business-critical applications.
- Implement and optimize database interactions using ORM frameworks such as Hibernate *and Java Persistence API (JPA)**, ensuring efficient and reliable data access.
- Develop asynchronous messaging solutions using *Java Message Service (JMS) to enable decoupled and scalable communication between distributed systems.
- Manage complex transaction scenarios to maintain data integrity and consistency across multiple services.
- Write comprehensive automated unit and integration tests using JUnit *and Mockito** to ensure code quality and reliability.
- Manage project builds and dependencies using Maven, and maintain version control with Git.
- Collaborate closely with DevOps teams to integrate APIs into CI/CD pipelines, ensuring smooth and automated deployment processes.
- Work within an agile development environment, participating in sprint planning, daily stand-ups, and retrospectives to deliver high-quality software iteratively.
- Utilize *Linux environments and shell scripting to automate routine tasks, troubleshoot issues, and optimize system performance.
- Ensure application security by implementing best practices and adhering to security standards throughout the API lifecycle.
- Perform performance tuning and load testing to identify bottlenecks and optimize API responsiveness and scalability.
- Collaborate with cross-functional teams including product managers, QA engineers, and other developers to deliver end-to-end solutions.
- Stay current with emerging technologies and industry trends to continuously improve the API platform and development practices.
- Mentor junior engineers and contribute to knowledge sharing within the team.
