About the role
About the Position
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.
Our internship in the Singapore office runs for 12 weeks, from mid May to mid August, and you'll need to be available for the entire period. If these dates don't align with your academic schedule, we encourage you to apply to our Hong Kong Software Engineering internship instead, which can accommodate a wider range of start and end dates. At the beginning of the program, you'll spend time training in our Hong Kong office, and you'll also visit our New York office for a week, giving you the chance to learn and work alongside interns and full-time employees across our global offices.
If you’d like to learn more, you can read about our interview and team placement processes and get a sense of what our most recent intern projects looked like! You can also learn more about Jane Street’s internship program here.
About You
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:
- A top-notch programmer with a love for technology
- Intellectually curious, collaborative, and eager to learn
- Humble and unafraid to ask questions and admit mistakes
- Fluent in English
Please note: Jane Street will provide flights to and from Hong Kong as well as accommodation throughout the entirety of the program.
