Jane Street's summer internships and January "winternships" offer an exceptional opportunity to learn about the firm and the world's financial markets. Trading interns work with experienced traders to find and execute arbitrage strategies, hedge risk, and search for new opportunities. Research interns construct mathematical models, learn about relevant academic research, explore new ideas, and execute studies using Jane Street's massive research infrastructure. Development interns perform extensive, business-oriented work in OCaml. We also have internships in operations and infrastructure.
While proximity to graduation is an advantage, we routinely hire students of all tenure, from freshmen to post-doctoral scholars. In the last couple of years, we have had interns from Harvard, MIT, Princeton, Yale, Duke, Penn, Brown, Chicago, Carnegie Mellon, Stanford, Berkeley, Cambridge, and Hong Kong University of Science and Technology.
Internships take place in all three of Jane Street's offices: New York, London, and Hong Kong. Most summer interns also get a chance to visit a foreign office during their experience. Trading interns spend each half of the summer on a different trading desk.
Past interns have reported that the best part of the internship is the rich educational experience. Every week brings a mix of theory classes, mock trading sessions, and guest speakers, on top of careful one-on-one mentoring with experienced traders and technologists.
