Job description

Jane Street is looking to hire great software developers with an interest in functional programming. OCaml, a statically typed functional programming with similarities to Haskell, Erlang, F# and SML, is our language of choice. We’ve got the largest team of OCaml developers in any industrial setting, and probably the world’s largest OCaml codebase. We use OCaml for running our entire business, supporting everything from research to systems administration to trading systems. If you’re interested in seeing how functional programming plays out in the real world, there’s no better place.
