About the role
About the Position
We're looking to hire an experienced Software Engineer with a background working on programming languages to join us. Jane Street's OCaml Language team focuses on improving OCaml as a foundation for our ever-growing technology stack, in collaboration with the greater OCaml community. We work on many different aspects of the language, aiming to make it easier for developers to express their ideas in OCaml, to improve the performance of the generated code, and to make the OCaml compiler itself faster and easier to use.
Over the years, we’ve extended the type system with support for novel language features, re-engineered the optimizer ground-up, and added feedback-directed optimization. We also extend and enhance the surrounding toolchain, working on tools for profiling, debugging and generating documentation. The vast majority of our work is open-source, and we upstream as much as we can to the mainstream OCaml compiler.
About You
For this specialised role within the OCaml Language team, we are seeking candidates with multiple years of experience in practical language design and implementation in an industrial-strength implementation. Research experience and publications in programming languages is a plus, but not a requirement. No previous experience with OCaml or functional programming languages is required.
If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com.
