What Is a Java Integration Developer and How to Become One

By ZipRecruiter Marketplace Research Team

As a Java integration developer, your job is to design and develop software for new and old systems using Java and customize any existing software to meet the changing needs of your employer. Each application you make may require connections to commerce platforms, access to external databases, and an interface that works well with the core platform. In many cases, companies ask you to continuously improve an existing code base or modify a program to address new issues. The complex programming needs of the Java integration developer position mean that many employers offer training, so you do not need to be fluent with every system they use.

The primary qualifications for becoming a Java integration developer are three or more years of experience with software or application development and functioning knowledge of extensible back-end application frameworks. You need an understanding of web application development, business logic layers, relational databases, and simple web containers. Employers typically expect a bachelor's degree in computer science, computer engineering, or a related field, but they may waive this if you have enough experience. Before getting hired, you may need to go through a lengthy technical test, a face-to-face technical interview, and in some cases, a culture fit interview. Employers expect good judgment, and if you cannot resolve an issue with a project, they expect you to escalate it to the next level of support.
