We were founded by a small group of traders and technologists in a tiny New York office. Today, we have more than 2,600 employees across five global offices. We trade a broad range of asset classes on more than 200 venues in 45 countries.
Our goal is to give you a real sense of what it's like to work at Jane Street full time while also providing a truly unparalleled educational experience. As an intern, you are paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done.
As a Software Engineering intern, you'll learn how we use OCaml (our primary development language) in our day-to-day work, and gain exposure to the libraries and tools that are foundational to our internal systems.
Some teams also use Python, so depending on the project, you might do some work with Python as well.
During the internship, you'll be closely mentored by full-time software engineers. Mentors design intern projects based on their team's current needs and are heavily invested in helping interns build maintainable, high-quality software that is intended to reach production. The projects you will work on are as varied and diverse as those full-timers work on, covering a wide range of problems, from high-performance trading systems to programming language design and everything in between.
If you've never thought about a career in finance, you're in good company. Many of us were in the same position before working here. If you have a curious mind, a collaborative spirit, and a passion for solving interesting problems, we have a feeling you'll fit right in. We're more interested in how you think and learn than what you currently know. You should be:
