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'll be paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done.
We’re looking for passionate and inquisitive students interested in security and technology to join us in our New York office for a Cybersecurity internship. Our Cybersecurity Engineers are responsible for being on the front lines of guarding the firm from cyber threats through investigations and incident response, as well as building tools and automation to streamline, automate, and enhance workflows, and grow our capabilities.
Our Cybersecurity team is a skilled group of programmers and security experts who are dedicated to keeping the firm safe. We consider ourselves to be tapped into developments in the broader cybersecurity space, and we can tell the difference between the latest cool hack by security researchers and what actually matters in our day-to-day work.
While wearing the hat of an investigator, you’ll be investigating alerts, digging through activity chains, and hunting and responding to evil. You’ll gain an understanding of a wide variety of log sources, systems, and tooling, primarily in-house developed or open source.
While wearing the hat of an engineer, you’ll learn good development practices and solve real problems with code so that we can detect and respond better, faster, and at scale.
You will also learn how to act as an ambassador of best practices to the rest of the firm. A key part of our mission is to bring everyone at the firm along with us on the cybersecurity journey, and you should be excited to learn how we think about security, trade-offs, and sustainability, and to educate the firm about risk and best practices with that in mind.

Jane Street Insights
What We Do
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.
