The role

Job descriptionOverview

At Susquehanna, quantitative researchers tackle challenging data and algorithmic problems that inform decision-making in global financial markets. Their work spans statistical inference, optimization, market microstructure, simulation, forecasting, and large-scale data analysis, drawing on a broad quantitative toolkit to develop new insights and approaches.

As a Quantitative Research Intern, you’ll gain experience that closely reflects the work of our full-time research teams while participating in a structured education program designed to accelerate your development. Through hands-on research, mentorship, and close collaboration with researchers, engineers, and traders, you’ll explore open-ended questions, design experiments, develop quantitative models, and evaluate ideas through rigorous empirical analysis.

Susquehanna’s extensive proprietary datasets and large-scale computing infrastructure—including a rapidly growing cluster of thousands of high-end GPUs—support computationally intensive research, large-scale simulation, and rapid experimentation. Researchers work in small, highly collaborative teams where ideas are debated openly, evidence guides decisions, and promising research can quickly produce practical impact.

Your Internship Experience

Your internship begins with Core Curriculum, an immersive, interdisciplinary program in which quantitative and machine learning researchers, traders, and software engineers learn together. You’ll build a shared foundation in quantitative trading, programming, data analysis, mathematical modeling, and modern machine learning and AI tools before applying those concepts to real-world problems.

You’ll spend the rest of the summer on the Blast Project—an end-to-end simulation of quantitative work ’ll research and develop a model, turn it into a trading strategy, and run that strategy against high-fidelity historical market data. Each day, you’ll receive measurable feedback on its performance, allowing you to test hypotheses, refine your approach, and iterate rapidly—much as our research and trading teams do.

The project is deliberately broad. Rather than exposing you to just one narrow aspect of the job, it takes you through data analysis, modeling, implementation, simulated execution, evaluation, and the judgment calls in between. That breadth leads to continuous, engaging conversations among interns and mentors—and helps make the Blast Project one of the most memorable parts of the summer.

The strategy is your own, but you won’t develop it alone. You’ll be paired with a mentor from our research and trading staff, supported by dedicated teaching assistants, and surrounded by a cohort of interns working through the same challenge.

We’re looking for intellectually curious researchers who are energized by difficult quantitative problems and motivated by rigorous experimentation.

You may be a strong fit if you have:

• A masters' degree in progress, graduating in 2027 or 2028, in computer science, economics, electrical engineering, mathematics, operations research, physics, statistics, or another highly quantitative discipline
• A strong foundation in probability, statistics, optimization, numerical methods, or quantitative modeling
• Experience developing research code in Python and working with large datasets; experience with C++, scientific computing, or high-performance computing is a plus
• Excellent problem-solving skills and an interest in using quantitative models to better understand complex systems
• Strong communication skills and an interest in collaborating with researchers, engineers, and traders to refine ideas through discussion and experimentation
• A track record…
