There’s a lot of debate in the industry about the difference between a Java software engineer and a Java developer. Some say that the largest difference is the title and pay schedule -- which does, of course, matter. Skills wise, it’s fair to say that a Java software engineer will probably be expected to be more of a computer science generalist with a strong speciality in Java who can also work in large teams. This means that you will be expected to code in other foundational languages (like C++ for example) as competently as you do in Java.
