Software Engineer - Data Analysis in London

We\’re always hiring software engineers for all of our offices. We are big believers in functional programming and use OCaml, a statically typed functional programming language, as our primary tool. More recently, Python has become a vital part of Jane Street’s research and trading work, acting as the go-to language for data analysis, visualization, and machine learning. We also believe in the value of open source software, using it in our daily work and releasing over a million lines of our own code as open source. Top-notch programming skills we use software to approach a variety of problems, so we\’re interested in everything from machine learning to systems administration to programming language design Software engineering at Jane Street is highly collaborative, and we are looking for people who can work effectively in small, close-knit teams We don’t expect you to have experience with functional programming, OCaml, Python, or finance; Fluency in English required If you\’d like to get an idea of what we cover in our software engineering interview process, you can visit our interview prep page .
