About You - You have a background in programming languages - You are excited to build out a widely used, but relatively young language - You are eager to work with a wide variety of end users, and to help build tools that empower them - 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 [email protected] .
