As Jane Street grows, the quality of the development tools we use matters more and more. We increasingly work on the OCaml compiler itself: adding useful language features, fine-tuning the type system and improving the performance of the generated code. Alongside this, we also work on the surrounding toolchain, developing new tools for profiling, debugging, documentation and build automation.

We’re looking to hire a developer with experience working on compilers to join us. That experience might be from working on a production compiler in industry or from working on research compilers in an academic setting. No previous experience with OCaml or functional programming languages is required.

We’re looking for candidates for both our London and New York offices, and you can apply here.
