Jane Street is looking to hire an experienced compiler engineer to work on improving the OCaml compiler. The focus would be on performance-related improvements to the compiler and runtime system. The job would also include working on other aspects of the compiler and the supporting toolchain including our internal development tools. We’re particularly interested in people with experience in areas like optimization, GC and language runtimes, and are happy to consider candidates who are not (yet) OCaml experts. The position would be full-time, and could be based in either London or New York.

If you’re interested (or know someone I should reach out to), please email me directly, at yminsky@janestreet.com.
