Something like job 'write translations for KDE programs' is just fine. You need to understand that KDE is an Open Source project, so there's no payment for these jobs. Otherwise, good knowledge of musical notation and theory. While GUI elements are already well localized in more than 32 languages, the help pages and other documentation items are much less representative. No CVS access required.
Examples are the collections of sample applications that come with any commercial office suite.
Hunting and reporting bugs and usability problems during normal use is an important part of this job.
