Ahrefs jobs – OCaml Developer

Requirements

: Proficiency in OCaml Knowledge of C++ is a plus but not essential The ideal candidate is expected to: Independently deal with bugs, schedule tasks and investigate code Make well-reasoned technical choices and take responsibility for them Understand the whole technology stack at all levels: from network and user-space code to OS internals and hardware Handle full development cycle of a single component i.e. formalize task, write code and tests, setup and support production, resolve user requests Approach problems with a practical mindset and suppress perfectionism when time is a priority Write flexible, maintainable code and adapt to post-launch requirements/tweaks These requirements stem naturally from our approach to development with fast feedback cycle, highly-focused personal areas of responsibility and strong tendency to vertical component splitting. If your preference is leaning towards making the web functional and working on user-facing stuff, you may want to consider our ReasonML position instead.
