Jane Street is a quantitative trading firm with a unique focus on technology and collaborative problem solving. Our trading is based on our own proprietary models and on our busiest days, we engage in over a million trades.
With offices in New York, London, Hong Kong, and Amsterdam, Jane Street is a trading firm that operates around the clock and around the globe, trading a wide range of financial products, including: ETFs, Equities, Futures, Commodities, Options, Bonds and Currencies.
Technology is at the core of how we approach trading, and we consider ourselves as much a technology company as a trading firm. We use OCaml (a statically typed functional programming language) as our primary development language.
Our key to success isn’t brand recognition, but people. Our growth comes from hiring and training amazing people and giving them the tools they need to innovate. The environment at Jane Street is open, informal, intellectual and fun. You can wear a t-shirt and jeans to the office every day, the kitchen is stocked full of complimentary food, there’s a gym and a games room onsite, and discussions are always lively. Teaching and learning are central activities at Jane Street through classes, mentoring and discussion.
