OCaml Developer
Ahrefs
Keyword research and backlink analytics SaaS
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++.
This role is based out of one of our offices — Palo Alto, Cambridge (MA), Singapore or Tokyo. You can be based in whichever of these you have the legal right to work in, but this is an on-site role: we're looking for someone who'll be in the office with the team.
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 offer:
Location: Palo Alto, Cambridge (MA), Singapore or Tokyo — on-site
Ahrefs does not engage with agencies or third party recruitment solutions for the roles we hire for. If at any point we need help, we'll let you know!
