Software Developer – Full time & summer internship positions

(Stageplek voor Informatica, Informatiekunde, Natuurkunde, Wiskunde)

Position Description

Jane Street is a quantitative trading firm with a focus on technology, a scientific approach, and a deep understanding of the markets. We are a global liquidity provider and market maker, operating around the clock and around the globe, employing over 800 people in our offices in New York, London, Hong Kong and Amsterdam.

The markets change rapidly, and we need to change faster still. Every day, we come to work with new problems to solve, new systems to build, and new theories to test. Technology is at the core of how we approach that work and developers are intimately tied in to every area of the business.

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.

We’re constantly recruiting for Full Time Developers.

We also run a summer internship program and intern applications are typically open from late summer until early winter. Our internship program is very competitively paid. Interns are given the opportunity to engage in software and research projects that have real and lasting impact. If you’d like to learn more about summer intern projects, check out this recent blog post.

Interns work on at least two projects in different areas, collaborating closely with full time developers. London interns will also get to spend time in our New York office as part of their internship. Interns also have access to many classes and lectures, including a speaker series that brings in some of the world’s top speakers on a broad array of topics.


You should have:

  • 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 developers and teach them what they need to know.
