I have a theory if you want a haskell job you have to compromise heavily on many other aspects of job criteria such as salary, preferred location, interest in the domain etc. Why? Because there are so few of those jobs that it is highly selective and leaves you no selectivity for other aspects.
Want $300k + Haskell? You better be someone who wrote GHC!
Want $300k without Haskell? Just need US residence, and coding skills and be a bit ruthless.
I think a good Haskell job is the on where you build your own micro SaaS using Haskell.
