Quantitative Research Internship - PhD: Summer 2026

Overview

As a Quantitative Research and Systematic Trading Intern at Susquehanna, you will work on projects that model the work of our full-time employees. You will also go through a comprehensive education program and interact with mentors who are at the top of their field, allowing you to build foundational knowledge in quantitative finance.

 

When exploring quant internship opportunities, students are typically looking for:

 

• Applications of probability, statistics, and other mathematical tools to real-world problems in the financial markets
• Warm, friendly, and supportive colleagues
• A place where they feel comfortable asking many, many questions
• An open environment that allows them to collaborate with multiple teams
• A culture that values transparency and integrity
• A place where they can envision long-term growth

 

Susquehanna combines all of the above to provide the best quant internship program in the industry. Join us to see why so many previous quant interns decide to return for a full-time career.

 

What we’re looking for

• Students who will be in their 4th or 5th year of their PhD program during the summer of 2026 studying in a quantitative field such as Mathematics, Physics, Statistics, Electrical Engineering, Computer Science, Operations Research, or Economics
• Exceptional mathematical problem-solving skills
• Strong communication skills in a fast-paced and/or highly collaborative environment are essential
• Strong, practical computing skills; a specific language proficiency is less important than your ability to get computers to accomplish tasks efficiently and reliably
• Experience working on in-depth research projects

Recruiting for this position will begin July 2025.

 

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

 

Susquehanna does not accept unsolicited resumes from recruiters or search firms. Any resume or referral submitted in the absence of a signed agreement will become the property of Susquehanna and no fee will be paid.
