Quantitative Researcher

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 challenging classes, interactive sessions, and group discussions. You will then have the chance to apply those lessons practically.

As an intern, you will be paired with full-time employees who act as mentors, collaborating with you on real-world projects that are essential to the firm. When not working on your project, you will have access to office amenities, physical and virtual educational resources, guest speakers, social events, and opportunities to engage with the areas of our work that interest you most.

If you have never considered a career in finance, you are not alone. Many of us were in the same position before joining. If you have a curious mind, a collaborative spirit, and a passion for solving interesting problems, you will fit right in.

About the Position

As a Quantitative Research intern, you will work alongside full-time employees to learn how we identify market signals, analyze large datasets, build and test models, and develop new trading strategies.

At Jane Street, we blur the lines between trading and research, fostering a collaborative environment where teams work closely to solve complex problems. We do not rely on one-size-fits-all modeling solutions; instead, we apply a variety of statistical and machine learning techniques, from linear models to deep learning, depending on the problem.

Our advanced proprietary trading models are the backbone of our operation, enabling us to identify profitable trading opportunities across hundreds of thousands of financial products in over 200 trading venues worldwide. We utilize petabytes of data, a computing cluster with hundreds of thousands of cores, and a growing GPU cluster containing thousands of A/H100s to develop trading strategies in dynamic, adversarial markets.

During the program, you will focus on two projects, mentored closely by key stakeholders. You may conduct studies on new or existing datasets, build tools to support the firm’s research, or explore big-picture questions that remain unresolved. The problems we address rarely have definitive answers and often require insights from colleagues with diverse expertise.

You will gain a deeper understanding of the research challenges we face daily, including dataset generation, time series analysis, feature engineering, and model building for financial data. Your project work will be complemented by classes on market fundamentals, lunch seminars, and activities designed to help you understand the entire process of creating a new trading strategy, from initial exploration to productionizing a signal.

Most interns are current undergraduate or graduate students, but we also welcome applicants who have already graduated and are considering a career change into finance.

About You

We do not expect you to have a background in finance or any specific field. We seek smart, ambitious individuals who enjoy solving challenging problems. While most candidates have experience with data science or machine learning, we value your approach to thinking and learning more than your current knowledge. You should be:

• Able to apply logical and mathematical thinking to various problems
• Intellectually curious; eager to ask questions, admit mistakes, and learn new things
• A strong programmer comfortable with Python
• An open-minded thinker and precise communicator who enjoys collaborating with colleagues from diverse backgrounds and expertise
• Research experience is a plus
• Fluent in English

Please note: Jane Street will provide flights to and from Hong Kong as well as accommodation throughout the entire program.
