Quantitative Trading Internship - Summer 2026

Overview

The trading group at GTS is looking for 2026 summer interns to work on a variety of projects in the quantitative trading space, such as: building analytics tools to assist traders making real-time trading decisions, analyzing historical trade data to draw insights and inform our trading strategies, designing and testing quantitative models for new strategy development. Interns will be working directly with senior traders throughout the program and have a strong influence on the direction that their projects will take. They will gain insight into how the trading desk operates and how our traders evaluate trading opportunities. They will see their work directly impact the group’s activities and drive revenue.

This program is the perfect preparation for those who will be seeking graduate positions in quant trading. The ideal candidate will be a high achiever with a strong quantitative background. They should be very comfortable working in Python and eager to improve. They will have a lot of initiative, exceptional problem-solving abilities, and thrive in a competitive environment. They should have an interest in building their understanding of trading, but a background in finance is not strictly necessary. If you have the quantitative skills, we can teach you the rest.
