Backend Engineer, Aiven

• 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

Desirable

• 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
