Обязанности

We're looking for a Backend Engineer to join our small, focused ClickHouse team. You'll work on the systems that power our managed ClickHouse service – building, scaling, and operating infrastructure that thousands of customers depend on daily.
You'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'll work in a modern async-first Python codebase alongside engineers who care about code quality, type safety, and automation.
If you have experience with ClickHouse internals or C++ – even better. But what matters most is strong backend fundamentals and a genuine interest in databases and distributed systems.
Design, build, and maintain backend services in Python (FastAPI, asyncio, psycopg2) that manage the ClickHouse service lifecycle
Work with CI/CD pipelines (Buildkite, GitHub Actions) to ship code reliably and often
Investigate and resolve production issues across the stack – from Python application code down to Linux system behavior
Contribute to technical planning within a small team where your input directly shapes the roadmap
Write well-tested, type-checked code and participate in thorough code reviews
Use AI coding tools as part of your daily workflow to accelerate development

Требования

Solid Python development skills -- you write clean, production-grade Python and understand async patterns (asyncio, aiohttp)
Strong understanding of databases -- you know how relational and analytical databases work under the hood, not just how to query them
Deep Linux knowledge (Fedora preferred) -- comfortable with systemd, process management, filesystem internals, and debugging at the OS level
CI/CD experience -- you've built and maintained delivery pipelines, not just used them
Familiarity with automated testing -- unit, integration, and system tests are part of how you work
Experience with AI coding tools -- you actively use AI-assisted development in your workflow and understand how to get the most out of it
Distributed systems awareness -- you understand the challenges of running services across multiple nodes and regions
Fluent English -- written and verbal

Будет плюсом

ClickHouse experience -- operational knowledge, query optimization, or contributions to the project
C++ or C -- ability to read and contribute to database engine code
Cloud infrastructure experience (AWS, GCP, Azure) with Terraform or similar IaC tools
PostgreSQL operational experience
Software and network security knowledge
