Taking on the most difficult trading challenges

Markets are defined by uncertainty. This is why quantitative thinking is crucial for our business. At Jane Street, we emphasize understanding the edge cases and tail risks that others overlook, and that matter most when markets deviate from expectations. We hire researchers and traders whose ideas and algorithms are informed by a deep mathematical fluency, and technologists who understand their systems from the hardware on up. We understand individual products and the context that informs their prices down to their subtlest details. This allows us to provide liquidity during the market’s most volatile moments.

All the pieces fit together

We work hard to untangle knotty problems together. Traders, researchers, and software engineers work in a tight loop to build our trading systems and implement strategies. Experts in distributed systems, security, networking, IT, and compilers build tools in support. Operational teams from legal and compliance to finance, tax, and HR help a complex global operation run smoothly. The institutional team works with clients to execute their transactions and provide liquidity. And leading talent in physical engineering, hospitality, and food services keep colleagues happy in our world-class offices.
