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 700 people in our offices in New York, London and Hong Kong.
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.
About the Role
We're always hiring software developers for all three of our offices. Technology is at the core of how we approach that work and developers are intimately tied in to every area of the business.
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. If you'd like to get an idea of what we cover in our software development interview process, you can read our recent blog post.
