Jane Street Capital is a global proprietary trading firm.(more about Jane Street)
At Jane Street, we consider trading and programming to be two ends of a continuum. As both a trading firm and a tech firm, we have room for people who love to trade, people who love to program, and people everywhere in between. Nearly all of our traders write code, and many of our developers trade. The role you carve out for yourself will be largely dependent on your strengths and the types of problems you enjoy thinking about.
Researchers at Jane Street are responsible for building models, strategies, and systems that price and trade a variety of financial instruments. As a mix of the trading and software developer roles, this work involves many things: analyzing large datasets, building and testing models, creating new trading strategies, and writing the code that implements them.
