At Jane Street, we consider trading and programming to be two ends of a continuum. As both a trading firm and a tech firm, we have room for people who love to trade, people who love to program, and people everywhere in between. Nearly all of our traders write code, and many of our software engineers trade. The role you carve out for yourself will be largely dependent on your strengths and the types of problems you enjoy thinking about.
Researchers at Jane Street are responsible for building models, strategies, and systems that price and trade a variety of financial instruments. As a mix of the trading and software engineering roles, this work involves many things: analyzing large datasets, building and testing models, creating new trading strategies, and writing the code that implements them.
About You
- Be able to apply logical and mathematical thinking to all kinds of problems. Asking great questions is more important than knowing all the answers
- Write great code. We mostly write in OCaml, so you should want to learn functional programming if you don't already have experience with it
- Have good taste in research. The problems we work on rarely have clean, definitive answers. You should be comfortable pushing in new and unknown directions while maintaining clarity of purpose
- Think and communicate precisely and openly. We believe great solutions come from the interaction between diverse groups of people across the firm

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.
