About the role

Banks, insurers, airlines and large retailers still run much of their business on Java, and the developers who understand it well are always in demand. As a Java Developer Intern at Crossing Infotech, you will learn how enterprise-grade software is built, from clean object-oriented design to services that talk to a database. You will work on real modules, get your code reviewed and see how professional teams keep large applications stable.

This is a hands-on, full-time remote internship for people who enjoy structured programming and want a strong foundation in one of the most trusted technologies in the industry.

What you will do

- Write clean, well-structured Java code using object-oriented principles

- Build and test simple REST services using Spring Boot

- Connect applications to MySQL databases using JDBC or JPA and Hibernate

- Work with collections, exception handling and multithreading basics in real tasks

- Debug and improve existing modules under the guidance of senior developers

- Write unit tests using JUnit to check that your code behaves correctly

- Use Git and GitHub for version control and take part in code reviews

- Share progress in daily check-ins and weekly review sessions

What we are looking for

- Good understanding of core Java and object-oriented programming (classes, inheritance, polymorphism, interfaces)

- Basic knowledge of SQL and relational databases

- Familiarity with the Collections framework and exception handling

- Exposure to Spring Boot is a plus, not a must

- Knowledge of Maven or Gradle, Postman and Git is a plus

- Patience for debugging and curiosity about how good software is designed

- A stable laptop and reliable internet connection for full-time remote work

Who can apply

- Final-year students or recent graduates from B.Tech, B.E., BCA, B.Sc (CS/IT), MCA or related streams

- Self-taught developers who can show their skills through a GitHub profile, coding practice profile or a personal Java project

- Anyone available to work full-time for the internship duration

What you will gain

- Experience of enterprise-style Java development

- Code reviews and guidance from experienced developers

- Java projects and code samples you can show in future interviews

- Internship completion certificate

- Freedom to work from your own city

Schedule

Full-time, Monday to Saturday or as assigned by your reporting manager, with daily check-ins and weekly review sessions.
