Summary ✨ AI‑Generated

An engineering organization is seeking an OCaml Backend Developer with strong knowledge of distributed systems, networking, operating systems, and efficient architecture. You will independently investigate bugs, make technical decisions, work across the software stack from network services to OS internals, and develop systems handling extremely large volumes of live data. C++ and Linux experience are valuable.

Highlights

Work on challenging backend systems involving large-scale data, networking, distributed systems, operating systems, and hardware-level concepts. The role emphasizes technical ownership, independent problem solving, thoughtful architecture, and close collaboration with an in-office engineering team.

Description

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. Ahrefs OCaml Basic Requirements:Proficiency in OCamlKnowledge of C++ is a plus but not essentialThe ideal candidate is expected to:Independently deal with bugs, schedule tasks and investigate codeMake well-reasoned technical choices and take responsibility for themUnderstand the whole technology stack at all levels: from network and user-space code to OS internals and hardwareHandle full development cycle of a single component i.e. formalize task, write code and tests, setup and support production, resolve user requestsApproach problems with a practical mindset and suppress perfectionism when time is a priorityWrite flexible, maintainable code and adapt to post-launch requirements/tweaksThese 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. What You GetWe offer: Competitive compensation packageInformal and thriving work atmosphereAbove-average perks and fringe benefitsFirst-class workplace (hardware, software, etc) in the modern officeLocation: 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.
