This is my periodic reminder to the FP world that Jane Street is looking to hire functional programmers. I've started getting the occasional inquiry coming in from people who are clearly unsure if our previous hiring announcements still apply, and I wanted to make it clear that they do. Also, I wanted to mention that I will be at parts of ICFP, CUFP and DEFUN this year, so if you're interested, come and talk to me there. Without further ado, and at the risk of boring longtime residents of the list to tears: Despite the problems besetting much of the financial industry, we have grown strongly in the last few years in our people, our technology, the scope of our business and its profitability. We now have over 30 OCaml developers, and we are actively looking to hire more in Tokyo, London and New York. For someone who cares about functional programming, Jane Street is an interesting place to consider. Jane Street has invested deeply in OCaml, to the point where we now have the largest team of OCaml programmers in any industrial setting, and probably the world's largest OCaml codebase--over a million lines. We really believe in functional programming, and use OCaml for everything from research to systems adminstration to trading systems. The atmosphere is informal and intellectual, with a focus on learning. The work itself is deeply challenging, and you get to see the practical impact of your efforts in quick and dramatic terms. Jane Street is also a small enough place that people have the freedom to get involved in many different areas of the business. Unlike many financial firms, software and technology are considered a core part of what we do, not some segmented-off cost center that the people who run the business don't think about. Jane Street is a place where people really care about the quality of the software, to the point that several of the most senior members of the firm, who do not have technology backgrounds, nonetheless review critical portions of the codebase before they can go into production. If you'd like to learn more, here are some links. First, there are a couple of papers we've written about our experiences here. http://www.janestreet.com/technology/articles.php We also have a technically-oriented blog: http://ocaml.janestreet.com For a (recruiting-oriented) overview of Jane Street, here's the firm website: http://janestreet.com If you're interested, send me a resume and cover letter. y
