According to TIOBE [1] Scala has moved up from 35 to 27 in the programming language popularity league in the last few months. The index is considered to be an indicator of how attractive acquiring a given language skill is for job prospects or as a basis for future project development. You find Scala appearing in more job postings and a casual browse through some of the job posting sites such as SimplyHired [2], Indeed [3], MySpace Jobs [4] or Trovit [5] will confirm the idea, You will notice Scala is typically combined with a requirement for Java experience too. This would appear to reflect the fact that new projects in Scala are likely to interface to existing Java applications or libraries. Companies seem to be leveraging the interoperability of Java and Scala to introduce the new language.
So it would seem that if you are a skilled Scala programmer with a solid experience in the Java/JVM environment then there could be more job opportunities out there for you. Amusingly even the site name squatters [6] think Scala Jobs have growth potential !
The question use to be "Are there paying jobs for Scala programmers?". Now the question has become "What would I find most interesting?"
For example, you speak French and always dreamed of working in Paris writing Scala for a living.
Well you can. There's a senior programmers post [7] with a leading on-line games software company, Mimesis Republic.
