As someone who hires for this work, I'm extremely dubious about hiring someone who is actively looking for a functional programming job. I've been burned before by PhD-type people trying to implement some theoretical thing rather than getting any work done. In the Joel Spolsky nomenclature, smart but doesn't get stuff done.

See the monthly Who is Hiring threads and search for functional, Haskell, OCaml, etc. https://news.ycombinator.com/item?id=41425910 has a few hits.
