At Citadel, Quantitative Research Engineers work closely with Quantitative Researchers to develop and implement automated trading system software solutions. These solutions utilize advanced statistical and quantitative techniques to tackle complex financial challenges. We seek candidates with a proven track record of excellence in their field and a strong desire to apply their advanced software engineering skills to systematic investing.  

 

As an intern, you’ll get to challenge the impossible in research through an 11 week program that will allow you to collaborate and connect with senior team members. In addition, you’ll get the opportunity to network and socialize with peers throughout the internship.  

Our signature internship program takes place June through August. Occasionally, we can be flexible to other times of the year. You will be able to indicate your timing preference in the application.

Citadel provides high-quality early-career entry through structured internships and named programs across investing, quant, and engineering, but access is highly selective and not designed for mass graduate hiring. Citadel is clearer than many finance employers on interview format in key tracks and offers strong on-the-job learning, yet pay transparency and published early-career outcomes are limited.
