Job Description

Jane Street is a technology-focused proprietary trading firm. We are looking to hire great software developers with an interest in functional programming. OCaml, a statically typed functional programming with similarities to Haskell, Scheme, 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.

We also have extensive benefits, including:

  • 90% book reimbursement for work-related books
  • 90% tuition reimbursement for continuing education
  • Excellent medical and dental insurance
  • Free lunch delivered daily from a selection of restaurants
  • Catered breakfasts and fresh brewed coffee
  • An on-site, private gym with towel service
  • Kitchens fully stocked with a variety of snack choices

Skills & Requirements

This specific role is for a programmer/tech generalist in our Hong Kong office. Your primary role will be to write software to support our trading, operations, and compliance groups. You will also spend some of your time doing trade support, where you will help to keep our critical systems and infrastructure running during Asia trading hours.

Our Hong Kong office is small, informal, and intellectual. The work is challenging and involved, and there are many opportunities to learn about different aspects of our business.

We are looking for a strong programmer who is excited about writing code in functional languages. If you don't know OCaml and know nothing about finance that's fine, but be prepared to learn. You should have experience using Linux and be comfortable on the command line. (Experience administering servers/Postgresql databases is a plus.) Good communications skills are a must: you will spend a lot of time working with people outside of the tech group, and a lot of time working with people in our other offices.
