Never seen a job ad on anything sharp other than C# in Europe.
There are occasionally LISP and Clojure jobs from what I can tell.
(It's also hard to find people on the talent side. I needed a Haskell developer with NLP skills in 2005, and could not find one so we had to port our codebase to Java.)
It's anecdotal, but on the F# Software Foundation's slack workspace[1], 4 out of the last 5 postings in the #jobs channel were in Europe.
No doubt, any company that picks a niche programming language as their business's lingua franca is taking a risk. For me, though, that is an indicator that they care about quality and do not have a culture of treating engineers as replaceable assembly line parts.
