Ahrefs is looking for a backend developer with deep understanding of networks, distributed systems, OS fundamentals and taste for simple and efficient architectural designs. Our backend is mostly implemented in OCaml with some C++ and Rust.
In this role, be prepared to deal with 25 petabytes of live data, OCaml and Linux on a daily basis.
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.
We are a small team that strongly believes that better technology leads to better solutions for real-world problems. We worship functional languages and static typing, extensively employ code generation and meta-programming, value code clarity and predictability, and constantly seek to automate repetitive tasks and eliminate boilerplate.
We are guided by DRY and follow KISS. If there is new technology that will make our life easier, we'll give it a try. We rely heavily on open-source code (as the only viable way to build maintainable system) and contribute back, see e.g. https://github.com/ahrefs
Our motto is first do it, then do it right, then do it better
