We are hiring Production Engineers in our London office. Jane Street Production Engineers are software developers who spend time both developing software and also providing high-quality support for software systems that are critical to Jane Street's trading business.
Many of our Production Engineers are embedded in various software teams; others are in standalone teams. In both situations we work alongside application developers with a common goal of creating and running great software systems. As a firm we are big believers in functional programming, and use OCaml as our primary development language.
Production Engineers play an essential role interacting with a wide variety of departments and functions at Jane Street. We solve real-time issues and make a firm-wide impact. We take ownership of the architecture and design of systems that monitor and support the firm’s trading. We also design and develop the tools that we use, and it feels great to be able to shape these tools and then enjoy the improvements.

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.
