Learning Haskell/OCaml may not be enough to land a job. Some places who use those languages have additional requirements (e.g. PhD, competitive interview process, math background, domain knowledge). And there are many experts in those languages that you'll be competing with.
That being said, expertise in FP can open the door to some very interesting jobs. I remember when I was a student (20+ years ago), the word was that FP was pretty much useless in the real world. While it's true that it's more niche than C++/JS, some teams use it, and it can give you an edge.
