About the Position

We are big believers in functional programming, using OCaml, a statically-typed functional programming language, as our primary development language. We also believe in the value of open source software, using it in our daily work and releasing hundreds of thousands of lines of our own code as open source.

This is a 10 - 12 week internship from September to December 2020.


About You

  • Top-notch programming skills.
  • Deep experience with—and love for—technology. There’s no specific checklist; we use code to approach a variety of problems, so we’re interested in everything from machine learning to systems administration to programming language design.
  • Strong interpersonal skills. Software development at Jane Street is highly collaborative, and we are looking for people who can work effectively in small, close-knit teams.

We don’t expect you to have experience with functional programming, OCaml, or finance; we’re happy to hire talented engineers and teach them what they need to know.

If you'd like to get an idea of what we cover in our software engineering interview process, you can read this blog post, and to get an idea of projects software engineering interns work on you can read this post highlighting a few of our Summer 2019 projects.

We hope to host this internship in our new London office. However, both our employees' and interns' safety and well-being are our main priority, and we may move this to a remote internship nearer the time. This internship is intended for those based in Europe and the UK.
