Quantitative Strategy Developer Internship: Summer 2026

Susquehanna International Group

Overview

Susquehanna is looking for highly motivated full-time students for our 10-week quantitative strategy development summer internship program. This is a computationally intensive role that will allow you to use your strong technical skills to solve problems at the intersection of trading, quant and technology.

Throughout the summer, you will receive education about how markets work by going through a deep dive into financial markets and Susquehanna’s approach to trading. You will also work on challenging projects for our trading strategy development teams in spaces such as signal creation and detection, quantitative strategy analysis, and low latency C++ strategy development. Additionally, you’ll have the opportunity to work on the desk side by side with senior developers who understand the nuances of building complex trading strategies.

Through splitting your time between working on a trading desk and participating in education in a classroom setting, you will receive the best preparation possible for a career in quantitative strategy development.

We will begin the recruiting process for this role in August.
