Overview

We’re looking for accomplished researchers who are interested in growing their career in the field of quantitative finance.

What You'll Do

As a Quantitative Researcher, you will investigate that idea by immersing yourself in market data, leveraging tools in mathematics, statistics, and programming.The general lifecycle of a quant project begins with an idea, what may come from anyone: you, the mentor who sits beside you, or someone you meet in the cafeteria.Through your research, you may discover a new pattern that can transform into a trading signal.You will work side-by-side with technologists in order to backtest your results and put that trading signal into production.Once that signal is embedded in our electronic trading strategies, you will continue to do research on that strategy in order to optimize its performance.As your trading strategy evolves, you will discuss with other researchers, strategists, and traders to collect feedback and brainstorm new ideas.Some of those ideas will turn into new quant projects, and the life cycle starts all over again.We have a comprehensive orientation program designed to bridge the gap between academia and industry. Education topics include an introduction to options pricing, exposure to our proprietary data sets, and opportunities to practice data analysis techniques. Beyond orientation, our trading floor serves as an unlimited source of discussion for learning and development.
