About Ahrefs →

The full posting

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 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.

What You Get

We offer:

  • Competitive compensation package
  • Informal and thriving work atmosphere
  • Above-average perks and fringe benefits
  • First-class workplace (hardware, software, etc) in the modern office

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!
