For the sake of clarity, this appears to be more of an IT / Tools Programming role, rather than a Game Programming role. There appears to be more flexibility with programming languages for such jobs.
Despite mentioning this, Serapth's point that C++ is not the 'end-all' stands. There are many examples of commercial games using other languages. For example, the massively multiplayer online role-playing game 'Star Wars Galaxies: An Empire Divided' is predominantly Java-based[1
]. The massively multiplayer online role-playing game 'EvE Online' is written in Stackless Python [3
]. Moreover, there are many examples of social games, casual games, indie games and serious games that are not made in C++.
