Google is pretty limited in the functional languages as a main tool for your job category. It's easy enough to sneak in functional things here and there, though.

Standard Chartered, where I worked before doing FP, is looking for Haskellers every now and then. Contact me (see profile) for some more info. Citrix is still using OCaml in Cambridge, UK, as far as I know. Not as much Haskell any more as they used to.
