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'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 Hong Kong 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.

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:

Currently majoring or planning to major in computer science or a similar field

Interested in cybersecurity and technology in your personal life, through activities such as CTFs, home labbing, and/or personal development projects

A strong programmer who can demonstrate high potential and an aptitude for learning

Interested in your tools, including your editor, computer environment, version control, etc.

Familiar with threat modeling and able to clearly communicate your understanding of trade-offs when it comes to security, risk, and usability

Able to explain the cybersecurity decisions you’ve made in your own life, and how you’ve approached thinking about those decisions

Able to adapt to changing scenarios and make challenging decisions under pressure

Humble about what you know and don’t know; not afraid to ask questions and admit mistakes

A curious problem solver with a positive, collaborative attitude

Someone who demonstrates perseverance and grit when investigating and learning new things beyond just a surface-level understanding

Fluent in English
