Ahrefs is looking for a C++ developer intern with the keen interest in developing database systems.
Clickhouse DBMS is the backbone of our infrastructure, holding multiple exabytes crawler dataset updated in realtime and building advanced and flexible analytics reports for our customers. Ahrefs team is overcoming multiple challenges to adapt the opensource Clickhouse DBMS to operate with distributed clusters of massive scale on bleeding-edge hardware.
What you will be working on:
- Collaborate with the software engineers teams in charge of data gathering and business logic to identify performance optimization opportunities for low latency massively parallel data processing, and work with other opensource contributors to improve Clickhouse performance and scalability. Implement optimizations specific to Ahrefs hardware and dataset to ensure data ingestion and queries perform efficiently on our infrastructure
- Improve the robustness and fault tolerance of the data infrastructure by improving edge cases and error handling inside the database code as reported by the devops team, and adapt features of the database to simplify operations
- Implement new features in the SQL interface and Clickhouse api to help business team develop new reports
- Help maintain Ahrefs specific fork of Clickhouse for features that cannot be upstreamed
Basic requirements:
- Experience in C++ (including C++20)
- Understanding of Unix/Linux systems
- Strong production debugging skills
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
- 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

Qui nous sommes
Nous sommes une petite équipe qui croit fermement qu'une meilleure technologie conduit à de meilleures solutions aux problèmes du monde réel. Nous adorons les langages fonctionnels et le typage statique, utilisons abondamment la génération de code et la méta-programmation, valorisons la clarté et la prévisibilité du code, et cherchons constamment à automatiser les tâches répétitives et à éliminer le passe-partout.
Nous sommes guidés par DRY et suivons KISS. S'il existe une nouvelle technologie qui nous facilitera la vie, nous l'essaierons. Nous nous appuyons fortement sur le code open-source (comme le seul moyen viable de construire un système maintenable) et contribute back. We occasionally blog on tech.ahrefs.com.
Notre devise est : faites-le d'abord, puis faites-le bien, puis faites-le mieux
