Full Stack Software Engineer - SQL Console

ClickHouse is hiring a Full Stack Software Engineer for its SQL Console team. The role builds interactive web applications, developer tools, and data visualizations for ClickHouse Cloud, with a focus on frontend performance and backend streaming services. It also involves taking ownership of ambiguous product problems and rapidly shipping maintainable features.

Responsibilities:

• Build highly interactive React web applications, developer tools, and IDE extensions handling real-time, high-throughput data streaming
• Optimize frontend rendering performance, state management, and DOM virtualization for large-scale datasets and complex visualizations
• Write high-performance Node.js / Express services when API, data streaming, or backend optimizations are required
• Act with a founder mindset: take ambiguous product problems, architect clean solutions, and ship maintainable code with high autonomy
• Leverage modern AI development tools (Cursor, Claude, Codex) as force multipliers to ship features rapidly

Requirements:

• Deep expertise in building complex, state-heavy web applications in React (Zustand, Redux, TanStack Query, or Context API)
• Proven ability to handle high-volume data rendering using DOM virtualization (react-window), Canvas/D3.js, or memoization techniques
• Strong hands-on experience writing asynchronous Node.js / Express microservices and streaming APIs
• Previous experience as a startup founder, side-project creator, or early engineer who thrives in fast-paced environments without rigid specifications
• Experience building VS Code extensions, web-based IDEs, query editors (Monaco), or developer tools
• Hands-on experience with ClickHouse or columnar real-time databases
