Jane Street is looking to solve the problem of creating high-quality documentation and training materials for their developers, as well as establishing a culture of great documentation as they grow.

Requirements

  • excellent writer
  • good enough at programming to navigate our codebase, work through our tutorials, and write up examples
  • experience with functional programming
  • expressive type systems
  • OCaml
  • finance

Responsibilities

    • Documentation. We’ve always believed that developers should spend time and effort documenting their own code, but at the same time, a great writer with a feel for the technology can raise the level of quality in a way that few developers can. Establishing a culture of great docs is especially important as we grow.
    • Building tools that support documentation. So much documentation is auto-generated by our systems, whether as error messages, logs, automated emails, or library docstrings. Getting your hands dirty hacking on documentation-adjacent tools will help not just to a first order, but will also make your other writing more effective.
    • Training material. We have a ton of programs that new and experienced hires go through, ranging from an OCaml Bootcamp to Dev Teach-ins that expose students to interesting technical problems from around the company. Part of the job is to make these better and mint more of them where valuable.
    • Writing longer pieces. We need more tutorials and overviews on a variety of topics. We have an internal developer handbook that we’re writing, with a backlog of chapters—each one an opportunity to dive deep into some part of our stack. But there’s also a lot of external writing to be done, for instance on our blog, our programming podcast, for conferences, recruiting events, and more.
