Who you are

Ahrefs is looking for a backend developer with deep understanding of distributed systems, OS fundamentals, reliability, networks, and a taste for simple and efficient architectural designs
This role is ideal for a SRE with a backend engineering background or a backend engineer who has an interest in SRE

What the job involves

Our backend is mostly implemented in OCaml with some D and C++, we use Puppet and OCaml for infrastructure as code, and we run on baremetal servers without any clouds (and we setup our datacenter halls ourselves)
In this role, be prepared to deal with 400+ petabytes of storage, OCaml and Linux on a daily basis (and CPU bugs occasionally)
Build monitoring and operations tools for developers
Build configuration as code tooling and use this tooling to setup infrastructure for product development needs
Work with the wider engineering team to understand what improvements are required
Take care of the large heterogeneous production infrastructure under high load
System and infrastructure analysis to understand performance, security and reliability improvements through the stack and coordinate with other engineering teams to implement them
Technologies:
OCaml (main day-to-day programming language)
Puppet (understand concepts, read and integrate with existing puppet code)
Distributed systems (everything is distributed here)
Modern C++ (investigating issues in external C++ codebases)
Linux kernel code (tracking down performance regressions, debugging, etc)
Clickhouse
OpenTelemetry
No docker
No cloud
