🚀 Internship

Software Engineer Internship, April - September

Jane Street

Oct 5

🚀 Off-cycle


Rolling basis


Our internships center around hands-on mentorship and a robust educational curriculum that includes challenging classes, interactive sessions, and small group discussions. Over the course of the off-cycle internship, you’ll be matched with full-time employees in your role who will mentor you as you tackle real-world projects they design. You’ll also be able to access our physical and virtual educational resources, attend guest speakers and social events, and hopefully get a real sense of what it would be like to work here full time.

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 nature, and a passion for solving interesting problems, we have a feeling you’ll fit right in.

Area of Responsibilities

Software Engineering


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 programme you’ll work on projects and will be 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. 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 (Summer 2022 edition coming soon!)
