Overview
At Susquehanna, quantitative researchers drive innovation from the centre of our trading floor. Leveraging expertise in probability, statistics, numerical analysis, stochastic optimisation, and machine learning, they play a pivotal role in developing and refining our trading strategies.
We are looking for PhD and research master’s students in their penultimate year of study to join our 10-week quantitative research summer internship. Run by a team of dedicated senior traders and quantitative researchers, our education programme is widely recognised as being the best in the industry. Don’t worry if you don’t come from a finance background – we will teach you everything you need to succeed.
A core strength of our internship is that our education is complemented by hands-on trading games and project work. Interns are immersed in a real-world algorithmic trading problem, learning about our proprietary dataspaces, novel modelling approaches, and strategy implementation.
Join us this summer to see why so many interns decide to return for a full-time career in quantitative research.
What We're Looking For
- Research-minded: You enjoy diving deep into a question and building mathematical models to reveal patterns in vast amounts of data.
- Analytical & detail-oriented: You approach problems with a curious and analytical mindset – building models, interpreting data, and uncovering insights with precision.
- Clear communicator: You enjoy building relationships with those you work closely with and are comfortable sharing ideas, expressing your thoughts, and listening to the views of others.
- Class of 2027 or 2028: PhDs (in penultimate or final year) and Research Masters students in quantitative fields such as Mathematics, Physics, Statistics, Electrical Engineering, Computer Science, Operations Research, or Economics. Successful interns will be invited to join the full time graduate programme in September 2027, January 2028 or September 2028.
