with rust, by contrast, which is ostensibly much less general purpose and hasn't been around as long there's already quite a collection and it's easy to see why it was chosen for those things.
Haskell jobs do exist, I have one of them. The big problem is that there are more people who want to do those jobs than there are jobs, so they seem very scarce.
But anyway there are also a number of investment banks I have heard that use Haskell as their “secret weapon” and do not advertise it, in fact those who could speak to details are all under NDA.
Personally I am hoping to help with this issue by building cool open source things in Haskell (and purescript)
I was skeptical for years for all the reasons you said, but I finally decided to set my skepticism aside and see for myself, and oh boy is Haskell great. It has a lot of problems, but I consider myself at least 2x more productive in Haskell.
Both Standard Chartered and Barclays loudly advertise that they use Haskell.
A quick web search turns up their job offers on Reddit, and both also send people to conferences such as Haskell eXchange, to talk about their team tasks, structure, and size. Example: [1]
Their code bases were discussed on HN before, e.g. [2].
Standard Chartered also funded the development of GHCs low-latency, non-stop-the-world, incremental GC, for 2 years until it was recently released [3].

For stuff that doesn't require that runtime (as convenient as it is) they just use familiar old lazy GHC. My understanding is that they are progressively moving more and more to GHC, although my knowledge is five years out of date.
A genuine one. I remember a presentation by a bank about their use of Haskell, and wasn't sure if it was Standard Chartered. I remember they had the subset, and mentioned they basically had to a lot from scratch to interface with various systems.
And now that I have the name, I found a link to someone's copy: https://dshevchenko.biz/hs-research/Haskell-in-the-Large.pdf (used to be available at code.haskell.org). My recollection of the paper isn't perfect :)

Ah, thank you!
I remember hearing this said about Perl back in the day! Language X is so awesome businesses use it in secret because they don't want their competitors to discover the secret to their success.
Not saying it couldn't happen, but you can say it about any language and it can't really be disproven.
This is why we need more publicity-visible Haskell success stories.
Really the thing that convinced me to really dig into haskell was that there were so many things that I wanted to learn but so much of the extra information had roots in haskell topics. So i basically said "to achieve my goals I need to know haskell even if i never use it for anything practical".
Slowly, as I learned more, I realized it is great. I wish I had chosen to learn haskell 10 years ago instead of like two years ago.
