Our vision is to help developers, builders, and creators bring their ideas to life with speed and simplicity, by providing a cloud data platform that makes open-source databases, search, streaming, and application infrastructure easily accessible to everyone.&amp;nbsp;&lt;/p&gt; &lt;h2&gt;The Role&lt;/h2&gt; &lt;p&gt;We&#39;re looking for a Backend Engineer to join our small, focused ClickHouse team. You&#39;ll work on the systems that power our managed ClickHouse service – building, scaling, and operating infrastructure that thousands of customers depend on daily.&lt;/p&gt; &lt;p&gt;You&#39;ll write Python that orchestrates database lifecycle operations, dig into Linux internals when things get interesting, and ship features through a well-established CI/CD pipeline. You&#39;ll work in a modern async-first Python codebase alongside engineers who care about code quality, type safety, and automation.&lt;/p&gt; &lt;p&gt;If you have experience with ClickHouse internals or C++ – even better.
