Driving the firm’s competitive edge, our quantitative researchers build next-generation models and advanced trading algorithms.
Start with an idea. Build it, test it and refine it. Make it great, then make it better. Receive fast feedback from the markets.
Our quants bring skills from a wide range of disciplines. They work side by side with engineers and traders. Quants apply their research quickly, seeing the impact of their work in the world.
Learn the fundamentals of capital markets, trading and statistics. Become fluent in the language of financial technology and adept at working with financial data.
Sharpen your research skills as an apprentice. Learn on the job with the support of industry-leading professionals and ongoing mentorship.
Benefit from practical instruction on leading teams, managing projects and communicating with colleagues.
Quants from our team answer some of our candidates’ most frequently asked questions.
We encourage initiative. People who take responsibility and accountability for projects are supported and rewarded and grow the fastest.
Excellence is our baseline. But you don’t need to be an expert on Day One; we’ll teach you. We want talented researchers who place a high degree of importance on precision, want to learn, can master new skills and continue to raise the bar together.
The problems we tackle do not have simple, check-the-box solutions. You will be exposed to real-world problems and must possess the ability to innovate and iterate from multiple angles with passion and persistence. We are excited by the opportunity to test our ideas—and keep doing so until we find a solution.
You should have an insatiable drive to seek out problems and identify their solutions. There is no shortage of interesting problems to work on, and the most successful quants are true self-starters who are eager to take on new challenges and solve difficult problems.
Our work is challenging. People who thrive here embrace failure as an opportunity to learn and keep pushing forward. You need to be able to share strong rationales for the solutions you propose and must be comfortable pivoting.
We value candidates who have a deep understanding of technology and the research process. If those qualities describe you, we can help you define your area of expertise and locate your niche within the industry.
It’s vital you possess these foundational skills, since you’ll be spending a lot of time modeling and forecasting, using statistics as a launching point. We can teach you everything you need to know about finance, but you should already have a robust statistical intuition.
Coding can be very useful in quantitative roles. Familiarity with computer science will help you learn quickly and get the most out of our proprietary tools.
Prior experience working with data will enhance your ability to understand its real-world applications and model information effectively. Many of your colleagues will come from non-computer science backgrounds like chemistry or physics, where they utilized these skills. This is invaluable as we develop new approaches to identify market signals.
A deep understanding of conducting and applying research is critical. Experience working on long-term research projects is extremely beneficial, but learning on the job is equally effective.
Some firms keep research and production separate. Here, we combine the two, making us faster and more agile. A new project can go from ideation, to deployment, to live trading within an hour.
We only hire extraordinary talent, without compromise. Our colleagues are extremely smart, driven individuals focused on achieving results. The opportunity for learning and growth at Citadel Securities is unrivaled.
Success is shared. We work with our peers and mentors to develop ideas together. When quants present work to their research team, they receive valuable academic-style feedback. The team pressure-tests ideas from all angles, asking nuanced questions and challenging specific elements to ensure the concept is as strong as possible. This dynamic engagement accelerates your growth and development.
