Trades stocks, bonds and funds as a market maker
We're looking for a Cybersecurity Engineer to help us mature our vulnerability management program. You'll join our Cybersecurity team, a skilled group of programmers and security experts dedicated to keeping the firm safe.
Vulnerability management is the focus of this role, but it doesn't tell the whole story—we want a well-rounded engineer whose knowledge spans the different facets of cybersecurity, because that broader perspective is what lets you reason well about real risk and where to spend effort.
Vulnerability management is a well-established part of how we keep the firm safe, and as we grow, we're continuing to invest in it, with a particular focus on automation and on scaling the program to keep pace with an expanding environment.
This is a hands-on, build-heavy role. We want someone with a strong technical foundation who isn't afraid to build something themselves, who has good judgment about what actually matters, and who can explain the "why" behind a risk and its mitigation. Manual triage doesn't scale at our size, so you'll lean on automation, including AI tooling paired with good judgment, knowing where it helps and when we need a human in the loop.
Your work will also include:

Trades stocks, bonds and funds as a market maker
Jane Street trades stocks, bonds, options, and exchange-traded funds with its own money as a market maker, a firm that constantly quotes prices to buy and sell so other investors can trade whenever they want. In 2025, it made more money from trading than JPMorgan Chase or Goldman Sachs, the biggest trading banks on Wall Street. Its traders, researchers, and engineers build computer-driven strategies that trade on exchanges and other venues around the world, and it also trades directly with large institutional clients. It earns the small gap between buying and selling prices across huge volumes, plus gains on positions it holds for minutes to days. Jane Street was founded in 2000 and is based in New York.
