Let’s look at which companies are most likely to hire a Java developer like yourself and what makes them great to work for. 

After all, companies hire Java programmers for a variety of exciting reasons and projects, so why wouldn’t you want to be a part of it? In this article, we’ll take a look at some of the businesses that hire Java software engineers and what you’d be expected to do if you were to accept a job there. 

Which companies want to hire a Java developer (and why) 

Java developers work mainly on the backend of websites and apps. The companies that are most likely to hire Java coders are financial services, consumer and retail services, supply chains, education, entertainment, and eCommerce companies. 

There are more than 175,000 Java developers in the US, but it’s not enough to satisfy the demand that exists, so many companies choose to hire a java programmer team in Eastern Europe or Asia to meet their needs.

In Eastern Europe, there is a much larger talent pool that can satisfy the demand. Companies like Lebara and Fluke hire Java developers in Ukraine, for example, alongside large global brands like Apple and Microsoft. There are about 50,000 Java developers in Ukraine and 375 vendors looking for Java developers. If you are based in Ukraine, chances are you will run across a company that wants to hire a Java coder to work on their own software or to work for one of their outsourcing clients. 

It’s an exciting place to work as there are also a wide variety of Java-related conferences that take place in the country, including JavaDay and Java Fest.  

What Does a Java Developer Do?

Java developers’ roles can vary. Some developers focus on app development, while others work with multiple languages or on software that may not be entirely Java-based. A Java developer may take part in the full software development lifecycle, from requirement analysis to deployment. 

Java is one of the older programming languages dating back to 1995. Today Java is part of Oracle. It’s a concurrent, class-based, and object-oriented programming language; designed to have as few implementation dependencies as possible. Compiled Java code can run on all platforms without recompiling the code. 

Java-based apps are known for speed and scalability, which is why they are used in software, computer games, mobile apps, and other applications. 

If you are a beginner, it’s a good idea to start with Java because it’s easy to break into (although there is a learning curve). Java is used in 2.6% of all websites whose server-side programming is known, and it’s used mainly by sites with high traffic volumes. LinkedIn,, and all use Java. 

If you know Java, it’s easier to learn the many languages that have descended from Java, including PHP, Python, Scala, and JavaScript. 

Smaller start-ups and companies usually don’t use Java, but as they scale and grow, they will likely switch to Java. That was the case with Twitter and UPS! If you are looking for stability and job security, Java is the best language to learn.

You may report to a senior project manager or IT manager all the way up the chain to the CIO. You will start as a junior or entry-level Java developer and work your way up to the senior level. Each designation has different responsibilities. 

You might start off working on program architecture as a junior and then work your way up to the senior level, where you are responsible for the overall functioning of the project. Titles may include design leads, software engineers, project managers, and more.

This requires training and a 180-minute assessment exam. 

You can also become an Oracle Certified Master, which requires 12 months of being an Oracle Certified Professional Java Programmer.
