Research and Technology Jobs at Jane Street

Jane Street Capital is a proprietary trading firm that operates around the clock and around the world. We bring a deep understanding of trading, a scientific approach, and innovative technology to bear on the problem of trading profitably on the world's highly-competitive financial markets. We run a small, nimble operation where technology and trading are tightly integrated.

At Jane Street, there is room to get deeply involved in a number of areas at the same time. We are actively looking for people interested in software development, system administration, and quantitative research--potentially all on the same day.

The ideal candidate has:

A commitment to the practical. One of the big attractions of our work is the opportunity to apply serious ideas to real-world problems.
Experience with functional programming languages (OCaml, SML, Scheme, Haskell, Lisp, F#, Erlang, etc) is important. Applicants should also have experience with UNIX and a deep understanding of computers and technology.
A strong mathematical background. This is a must for candidates interested in research, and includes a good understanding of probability and statistics, calculus, algorithms, etc. We draw on ideas from everywhere we can, so we value interest and experience in a range of scientific fields.
Good second-order knowledge. In trading, understanding the boundary between what you do and don't know is as (or more) important than how much you know.

The environment at Jane Street is open, informal, intellectual, and fun. You can wear a t-shirt and jeans to the office every day, the kitchen is stocked, and discussions are always lively. We encourage a focus on learning, both through formal seminars and classes, as well as through day-to-day conversations with colleagues. Other perks include competitive salaries, rapid advancement for people who do well, excellent benefits, free lunch, and a gym on-site.

We are currently looking for full-time positions as well as summer interns. If you are interested, send an application to Yaron Minsky including a resume, cover letter, and optionally some sample code you've written.

If you'd like to know a little bit more about how we came to use OCaml as our primary development language, take a look at these slides from a talk we gave at CUFP 2006, a conference for commercial users of functional programming.
