Jane Street is a quantitative trading firm with a unique focus on technology, a scientific approach, and a deep understanding of markets to guide our business. Our entrepreneurial culture is driven by our talented team of traders and programmers. We are a global liquidity provider and market maker, operating around the clock and around the globe, out of offices in New York, London, Hong Kong and Amsterdam.

The markets change rapidly, and we need to change faster still. Every day, we come to work with new problems to solve, new systems to build and new theories to test. We’re always looking for people to join us and help come up with that next great idea.

The environment is intellectual and collaborative, relaxed and playful, with a strong focus on education. You’ll learn about trading and our technology stack through in-house classes, guest lectures and on-the-job experiences. You’ll have the freedom to get involved in many different areas of the business and we’re small enough that you can quickly and clearly see the impact of your work.

Quantitative Trading

Our trading is based on our own proprietary models and on busy days we engage in over a million trades. Technology is at the core of how we approach trading, and we consider ourselves as much a technology company as a trading firm. We use OCaml, a statically-typed functional programming language, as our primary development language, and have the largest team of OCaml developers in any industrial setting.

Traders work in teams to seek out and trade on pricing inefficiencies, develop models, manage risk, investigate new products, and push into new business areas. Experienced traders teach and oversee the less-experienced. New traders serve as assistants while they learn the ropes, getting increasing responsibility as they demonstrate their ability to handle it.

You should be:

• Excellent quantitatively, with strong understanding of probability and statistics.
• An effective communicator in a close-knit team setting.
• Motivated, competitive and eager to learn.
• A responsible, adaptive and logical thinker.
• Interested in expanding technical skills; prior exposure to programming a plus but not required.

Undergraduate and graduate students from all disciplines are encouraged to apply. Previous experience or coursework in finance, business or economics is not required. We’re more interested in how you think and learn than what you know.
