Jane Street works differently. As a liquidity provider and market maker, the firm trades a broad range of asset classes on more than 200 venues in 45 countries and helps form the backbone of global markets. Jane Street's approach is rooted in technology and rigorous quantitative analysis, but its success is driven by its people. They innovate in tech, from functional programming to machine learning to programmable hardware. While Jane Street's proprietary trading business thrives, the firm puts its expertise and experience to work for its clients.
