Rust Developer


Ahrefs is looking for a backend developer who possesses deep understanding of networks, distributed systems, OS fundamentals and taste for simple and efficient architectural designs. Our system high-level logic is implemented in OCaml, while lower-level and performance critical parts are implemented in C++ and Rust with the intention to gradually switch all legacy C++ components to Rust and further performance sensitive parts to be implemented in Rust too.

In this role, be prepared to deal with 30 petabytes of live data, Rust, OCaml, Linux and Git on a daily basis.

Basic Requirements:

  • Proficiency in Rust will be highly appreciated, otherwise a strong inclination to intensively learn Rust in the short term will be required
  • Understands the general concepts of functional programming and/ or experience with other FP languages (F#, Haskell, Scala, Scheme, et al)
  • Knowledge of OCaml and/or C++ is also a plus

The ideal candidate is expected to:

  • Independently deal with bugs, schedule tasks and investigate code
  • Make well-reasoned technical choices and take responsibility for it
  • 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 (DevOps), 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.

Who We Are:

Ahrefs runs an internet-scale bot that crawls the whole web 24/7, storing huge volumes of information to be indexed and structured in a timely fashion. Our backend system is powered by a custom petabyte-scale distributed key-value storage to accommodate all that data coming in at high speed. With this data, Ahrefs builds analytics services for end-users in the Search Engine Optimization (SEO) space and a web-scale search platform.

We are a lean and robust team who strongly believe that better technology leads to better solutions for real-world problems.

Our motto is "first do it, then do it right, then do it better".

What you get:

At Ahrefs, we value our people and working here has never been more rewarding. We offer:

  • Competitive compensation package
  • Informal and thriving work atmosphere
  • First-class workplace equipment (hardware & tools)
  • Above-average perks and fringe benefits
