Quantitative Trading Internship: Summer 2027 at SIG

Susquehanna’s 10-week quantitative trading internship offers a rare insight into working at one of the world’s leading quantitative trading firms. Designed for intellectually curious and driven individuals with strong quantitative skillsets, our internship combines rigorous classroom-based education with real-world trading experience.

Run by a team of dedicated senior traders, our education programme is widely recognised as being the best in the industry. Our classroom-based education covers topics such as ETF and options trading, game theory, and programming. Don’t worry if you don’t have 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. Working alongside a dedicated mentor, you will have the opportunity to work on a real-world trading problem, which has the potential to impact our trading strategies, improve tools, or uncover new market insights.

Problem solver: You enjoy solving puzzles and love it when you discover solutions to complex problems.

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.

Penultimate-year or recently graduated student: You should have completed 3 years at university by June 2027. Successful interns will be invited to join our full-time graduate programme in either September 2027, January 2028 or August 2028, depending on availability.

What’s in it for you:

Education: You will attend classes covering a vast range of topics (Finance, Options, Mock Trading, Game Theory, Tech, Trader Talks, Poker, Speaker Seminars, In-house trading games… the list goes on!) from some of the most experienced employees at 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.

Decision-making: Game theory is central to Susquehanna’s history as a firm and our trading philosophy. Weekly poker classes, strategy board games, and proprietary trading games will challenge you to optimise outcomes, anticipate moves, and maximise your winnings.

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.
