This company is an ISP, was a telephone company once upon a time, and has a lot of underlying business systems that it takes to run it. My team writes the vendor integrations and custom software you can't buy off a shelf unique to this particular company.
A good chunk of our world is Microsoft .NET, so we have legacy C# applications lying around. Several years ago we wrote some new systems in Haskell and really enjoyed the FP experience but not the ecosystem. F# moves us closer to the business world while maintaining the FP experience we enjoy.
That's too bad, I would have loved to apply.
Modesty aside, I think I would be a great fit for the position, since I currently do a similar job (similar tasks and stack) and I am looking to move to another job.
But I am not based on the U.S.
