About the job
About the Role
Jane Street is seeking talented Software Engineers who are eager to contribute to the design and development of the systems and tools that drive our operations. Our Software Engineers are integrated throughout the company, tackling complex challenges that span from trading desks to accounting, as well as creating essential infrastructure, including network monitoring solutions and risk models.
We are strong advocates of functional programming, primarily utilizing OCaml, a statically-typed functional programming language. Recently, Python has emerged as a crucial component in our research and trading initiatives, serving as the primary language for data analysis, visualization, and machine learning.
In addition to our internal practices, we value the significance of open-source software. We actively incorporate it into our daily operations and have released over a million lines of our code as open source. We are continually looking for ways to enhance open-source projects and provide ongoing support for tools like Mercurial, the OCaml compiler, and the OPAM package manager. We welcome passionate engineers with experience in any programming language; most of our team members started with minimal practical knowledge of OCaml.
