Jane Street works differently. As a liquidity provider and market maker, we trade on more than 200 trading venues across 45 countries and help form the backbone of global markets. Our approach is rooted in technology and rigorous quantitative analysis, but our success is driven by our people.

Our bright, beautiful offices in the heart of New York, London, Hong Kong, and Amsterdam are open and buzzing with conversation. We come from many backgrounds and encourage travel between offices to share perspectives. Some of our best ideas come from bumping into a visiting colleague at the office coffee bar.

Markets move fast. Staying competitive as we’ve grown has required constant invention—of new trading strategies, technology, and processes. We’ve found this is easier when you hire humble, kind people. They tend to help each other, and prioritize teamwork over titles.

We invest heavily in teaching and training. There’s a library and a classroom in every office, because deepening your understanding of something is considered real work. Guest lectures, classes, and conferences round out the intellectual exchanges that happen every day.

People grow into long careers at Jane Street because there are always new and interesting problems to solve, systems to build, and theories to test. More than twenty years after our founding, it still feels like we’re just getting started.

Software Engineer Internship

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&nbsp;course of your internship, you will explore ways to approach and solve exciting problems within&nbsp;your field of interest through fun and challenging classes, interactive sessions, and group&nbsp;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&nbsp;on real-world projects we actually need done. When you’re not working on your project, you will&nbsp;have plenty of time to use our office amenities, physical and virtual educational resources,&nbsp;attend guest speakers and social events, and engage with the parts of our work that excite you&nbsp;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. 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 work you will do is as varied and diverse as what full-timers work on, covering a wide range of problems, from high performance trading systems to programming language design and everything in between.&nbsp; 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! 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 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&nbsp;throughout the entirety of the program. If you're a recruiting agency and want to partner with us, please reach out to&nbsp;agency-partnerships@janestreet.com.
