Software Engineer Internship (Dec 2024)

About the Program

Our goal is to give you a real sense of what it’s like to work at Jane Street full-time. Over the course of your internship, you will explore ways to approach and solve exciting problems within your field of interest through fun and challenging classes, interactive sessions, and group discussions — and then you will have the chance to put those lessons to practical use.

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. When you’re not working on your project, you will have plenty of time to use our office amenities, and physical and virtual educational resources, attend guest speakers and social events, and engage with the parts of our work that excite you the most.

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.

About the Position

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.

During the program you’ll work on two projects, mentored closely by the full-time employees who designed them. Some projects consider big-picture questions that we’re still trying to figure out, while others involve building something new. Your mentors will work in two distinct areas, so you’ll gain a better understanding of the wide range of problems we solve every day, from high-performance trading systems to programming language design and everything in between.

About You

We don’t expect you to have a background in finance, OCaml, functional programming, or any other specific field — we’re looking for smart people who enjoy solving interesting problems. We’re more interested in how you think and learn than what you currently know. You should be:

• A top-notch programmer with a passion for technology
• Collaborative and courteous with strong interpersonal and communication skills
• Eager to ask questions, admit mistakes, and learn new things
• 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.
