Financial firms that deal with banking, investing, and trading employ mathematicians. These firms include Goldman Sachs, Capital One, RBS, ING, and Jane Street.

In 2017, the BYU math department took a group of 18 students to Europe for four weeks to visit companies that hire mathematics students. One of the companies the group visited in London was Jane Street, a quantitative financial trading firm. The group’s contact was a mathematician working for Jane Street. During the visit, the students learned about what the company does, what financial trading is, and how mathematics is involved.
