I don't know, I'm working at Treyarch, which is in Los Angeles, but our company (Activision) has studio in New Jersey (or New York).
But I think any big enough game developer studio would be happy to employ someone with such knowledge. From my narrow (have been for 10 years in the same studio) view - we often need people that do know MySQL, SQL in general, and other things that are not generally needed directly in game development - drivers, monitors (file, network, etc.), web servers, etc.
Just imagine if every PRINT() in your game actually dumps all that info in some server, and does not slow down you. You can do a lot of with that info - it can log what level you are playing, when, who is playing, which build, various settings, what you've killed, what textures were used, etc. Later there might be tool pulling that data and analyzing it.
