We think big, start small, and move fast.

Who we are

Ahrefs Pte Ltd is looking for a backend developer to join our small high-skilled team of professionals.

At Ahrefs we have built an internet-wide crawler and a custom distributed petabyte-scale database to store the index of the whole Web. On top of that we are currently building various analytical services for end-users. This is where you will be able to apply your skills and push the world forward.

We are a small company enjoying global visibility of our work and vivid feedback from users, with an everyday opportunity to leverage our skills to maximum potential, limited only by our own ideas.

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

What we need

Our backend is implemented in OCaml, as such the knowledge of OCaml is a big plus. Otherwise, understanding of functional programming in general and interest in learning OCaml is required. The candidate will have to deal with the following technologies on the daily basis:

• networks & distributed systems

• 4+ petabyte of live data

• OCaml

• linux

• git

Knowledge of C++ is a plus.

The ideal candidate is expected to:

• Independently deal with and investigate bugs, schedule tasks and dig code

• Make argumented technical choice and take responsibility for it

• Understand the whole technology stack at all levels : from network and userspace 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)

• Approach problems with practical mindset and suppress perfectionism when time is a priority

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.
