Rust Developer


What we need

Ahrefs is looking for a backend developer who has 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.

In this role, be prepared to deal with 25 petabytes of live data, Rust, OCaml, Linux on a daily basis.

Basic Requirements:

  • Proficiency in Rust
  • Experience with tokio and asynchronous code
  • Knowledge of OCaml and/or C++ is 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 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 (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:

We are a lean and robust team who strongly believe 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 are constantly seeking to automate repetitive tasks and eliminate boilerplate, guided by DRY and following KISS. If there is any new technology that will make our life easier - no doubt, we'll give it a try. We rely heavily on opensource code (as the only viable way to build maintainable system) and contribute back, see e.g. It goes without saying that our team is all passionate and experienced OCaml programmers, ready to lend a hand and explain that intricate ocamlbuild rule or track down a CPU bug.

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

What you get:

We offer:

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

Work location for this role could be:

  • Singapore
  • Remote
