Quantitative Researcher - PhD

Position: Quantitative Researcher - PhD: 2026
Overview

As a Quantitative Researcher at Susquehanna, you'll blend strong research capabilities with a deep understanding of trading to design, validate, backtest, and implement statistical and advanced machine learning models.

* Collaboration. Work in an open environment that allows you to collaborate with systematic traders and technologists to push strategies into production

What we're looking for

* PhDs graduating by Summer 2026 or postdocs in quantitative fields such as Mathematics, Physics, Statistics, Electrical Engineering, Computer Science, Operations Research, or Economics

* Analytical problem-solvers with excellent logical reasoning and a passion for turning data into decisions

* Clear communicators in a fast-paced and highly collaborative environment

* Programmers comfortable processing and analyzing large data sets in Python; experience with C++ (or another low-level language) is a plus

* Strategic thinkers with demonstrated interests in strategic games and/or competitive activities

* Self-motivated and quick to learn, thriving in dynamic, fast-moving environment

By applying to this role, you will be automatically considered for the Quantitative Systematic Trader position. There is no need to apply to both positions to be considered for both.
