We invest in extraordinary colleagues

The secret to our success is no mystery. It’s our people.

We bring together the brightest minds across mathematics, engineering, finance and beyond to solve the market’s most critical challenges.

What we do

Citadel Securities is a leading global market maker. We trade at the intersection of major global markets. We deploy powerful predictive models and leverage sophisticated technology to execute trades at scale and solve some of the most important market challenges of our time.

As a result, investors can reliably access the markets, whether they’re retail investors saving for retirement or institutional investors managing pensions for thousands of employees.

We also go a step further to be a leading voice on how to enhance the markets so tomorrow they’ll operate even better than they do today. We believe when the markets are more competitive, everybody benefits.

Our culture

Together we achieve more.

We embrace bold ideas and seize opportunities others don’t, from the way we operate to the strategies we deploy.

With a bias for action, our work goes into the market quickly. That’s because when solving for live problems, we have to operate in real time. The financial markets provide immediate feedback that propels our cycle of learning and impact.

Our relentless focus on innovation raises the bar for what’s possible. That’s as true for our work in the markets as it is for your career. It’s our collective intellect, skill and ambition that allow us to achieve far more together than we ever could on our own.
