What recruiters should know
Haskell has a tiny but stable job market in 2026. Its main commercial strongholds are quantitative finance firms (Jane Street is Haskell/OCaml-adjacent), formal verification, academic research, and aerospace. Haskell's type system and purity make it valued in safety-critical and mathematically rigorous contexts. The demand is small but consistent — experienced Haskell developers command premium compensation. Growing academic interest: Haskell is frequently used to teach functional programming concepts that transfer to Rust, Scala, and Elixir.
