Jane Street is actively hiring summer interns for our offices in New York, London and Hong Kong. Interning at Jane Street is a great learning experience. If you're interested in seeing how functional programming is applied to real world problems at big scale, there's no better place. Look here https://blogs.janestreet.com/?p=962 to get a sense of the kinds of projects summer interns do. As is reflected there, many of our intern projects make their way out as open-source projects. Interns also learn about Jane Street's trading business through lectures and interactive training sessions. Plus, there are a lot of fun social activities throughout the summer. Feel free to redistribute this to any students you think might be interested. And if you're interested directly, you can apply here: http://janestreet.com/apply And as usual, we're also hiring developers for fulltime positions in NYC, Hong Kong and London. Cheers, y (For the avoidance of doubt, note that summer internships are paid positions.)
