Intern will collaborate with engineers on database systems, optimize performance, enhance fault tolerance, implement SQL features, and maintain Clickhouse fork.
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.

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
