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.
About Jane Street:
Jane Street is a quantitative trading firm that uses innovative technology, a scientific approach and a deep understanding of markets to guide our business. We are a global liquidity provider and market maker, operating around the clock and around the globe, out of 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. We’re always looking for people to join us and help come up with that next great idea.
The environment is intellectual and collaborative, relaxed and playful, with a strong focus on education. You’ll learn about trading and our technology stack through in-house classes, guest lectures and on-the-job experiences. You’ll have the freedom to get involved in many different areas of the business and we’re small enough that you can quickly and clearly see the impact of your work.
You should have:
- Top-notch programming skills
- Deep experience with—and love for—technology. There’s no specific checklist; we use software 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.
