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, 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. We’re always looking for people to join us and help come up with that next great idea.
Software is an integral part of how we approach problems, whether we’re designing a trading strategy, managing the operational complexities of a new trade-flow, or administering servers in locations across the globe. Trading is a demanding business, and that means the standards for our software are high on every front, including clarity, performance, safety, and turnaround time.
We use OCaml, a statically-typed functional programming language, as our primary development language. Languages in this family, like Haskell, SML, F# and Scala, are sometimes seen as powerful but impractical, in part because they’re supposedly too difficult for the average programmer, and in part because no one else seems to use them.
