Quantitative Systematic Trading Internship: Summer 2027

Quantitative systematic traders represent a true hybrid of our core disciplines: trading, technology, and quantitative research. Drawing on their technical proficiency, research experience, and understanding of trading, quantitative systematic traders’ work involves identifying trading signals, developing strategies, and collaborating extensively with members of the trading, quantitative research, and technology teams.

Our quantitative systematic trading summer internship runs for 10 weeks. Managed 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 we combine our education with hands-on project work and trading simulations. Interns are immersed in a real-world algorithmic trading problem, learning about our proprietary dataspaces, novel modelling approaches, and strategy implementation. Additionally, quantitative systematic trading interns develop a deep understanding of trading decision-making by participating in various types of trading simulations.

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.
• Technically proficient: You have experience writing code to process and analyse large datasets.
• 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.
• Ambitious: You’re someone that enjoys setting personal goals and giving your all to achieve them. Be it in Arts, Sports, Academics, or another passion, you’re not afraid to put in the effort to reach your full potential.
• Class of 2027 or 2028: You’re a PhD or research master’s student in the penultimate year of study, majoring in a quantitative discipline.

Successful interns will be invited to join our full-time graduate programme in either September 2027, January 2028 or September 2028.

What’s in it for you:

• Education: You will attend classes covering a vast range of topics (Options Pricing, Machine Learning, Data Analysis Techniques, Game Theory, Trader Talks, In-house trading games… the list goes on!) from some of the most experienced employees in Susquehanna.
• Collaboration: You will get to work with a wide range of people in the classroom and through your project work; people who share a passion for mathematics, problem‑solving, game theory, and technology.
• Culture: Our non-hierarchical, casual, and collaborative culture allows employees of every level to thrive.
• Perks: We offer a highly competitive compensation package to our interns. Located in our brand new office in London’s city centre, our office features free onsite catering, a games room and dedicated education space.
