Core Software Engineer (C++) - Remote

As part of the ClickHouse Core teams, you will contribute to, analyze, and optimize the performance of the core ClickHouse database. The team works on many different topics such as query optimization, distributed query optimization, relational operators (e.g. aggregation and joins), caching, and low-level optimizations like SIMD instructions.

You will ensure that the database performance does not deteriorate over time by extending existing and adding new performance tests, based on real-world or synthetic datasets.

You will serve as a resource for the Support Engineering team, helping to debug the most advanced performance issues encountered by our customers. This includes an on call rotation as well as participation in our external community support channels.

As the core ClickHouse database continues to move at a fast pace, you will closely collaborate with our other teams to assess the impact of new features on performance and reliability

You will work with our open-source community. This will include resolving issues, reviewing and finishing PRs, answering questions from mail, chats, google groups, external Slack channels, etc.

You bring along solid professional software development experience in C++. This includes experience with Unix/Linux Systems.

You have strong knowledge in database internals and design.

You have experience in performance engineering, ideally in a database but other areas like high-frequency trading, simulation, real time data processing etc. are also okay.

You communicate well with others and have the ability to work well within and across engineering teams.

You are ready to work closely with our open-source community. You participate in code reviews with patience and attention-to-detail fostering a culture of collaboration and mutual respect.

You are a strong problem-solver and have solid production debugging skills.
