Senior Software Engineer - Rust (Integrations)

About the Team

The Integrations team is the bridge between ClickHouse and the entire data ecosystem. We build and maintain the connections that make ClickHouse accessible to millions of developers and data practitioners worldwide. Our work spans from low-level database drivers to high-level data visualization plugins, ensuring that ClickHouse seamlessly integrates with the tools our users already know and love.

We're responsible for the official language clients (Python, JavaScript, Java, Go, Rust, C++), major data connectors (Kafka, dbt, Spark, Fivetran), and integrations with leading visualization platforms (Grafana, Tableau, PowerBI, Metabase).

What will you do?

As a Senior Software Engineer specializing in Rust integrations, you'll be the architect and maintainer of ClickHouse's Rust ecosystem. This role sits at the intersection of high-performance database engineering and developer experience, where you'll craft zero-cost abstractions and memory-safe tools that enable Rust developers to harness ClickHouse's incredible speed and scale.

You'll own the full lifecycle of Rust-based integrations—from the core database driver that handles billions of records per second with minimal overhead, to SDKs and connectors that make ClickHouse feel idiomatic in Rust applications. You'll also drive integration with the rapidly growing Rust data processing ecosystem, including frameworks like Polars, DataFusion, Tokio-based streaming platforms, and emerging analytical libraries.

You'll collaborate closely with the open-source community, internal teams, and enterprise users to ensure our Rust integrations set the standard for performance, reliability, and developer experience. You'll also work on bridging ClickHouse with modern Rust data processing frameworks, enabling seamless data pipelines that span from ingestion to analysis.

About you:

• 5+ years of software development experience focusing on building and delivering high-quality, data-intensive solutions.
• Strong proficiency in Rust and its ecosystem, including advanced knowledge of ownership semantics, async programming, zero-cost abstractions, and performance optimization techniques.
• Experience with Rust's async runtime, concurrent programming patterns, and building high-throughput applications using channels, futures, and async streams.
• Strong understanding of database concepts: SQL, data modeling, query optimization, and familiarity with OLAP/analytical databases.
• Experience with Rust profiling and performance analysis tools, WebAssembly 
• Experience integrating with data processing frameworks and building connectors that enable seamless data pipeline workflows.
• Outstanding written and verbal communication skills to collaborate effectively within the team and across engineering functions.
• Passion for open-source development: actively engaging with the OSS community, advocating for users, and influencing the evolution of the core system through your contributions.

Bonus points for:

• Prior contributions to Rust open-source projects, particularly in the data/analytics space.
• Familiarity with ClickHouse or similar high-performance data platforms.
• Deep understanding of Rust's data processing ecosystem: experience with libraries like Polars, DataFusion, Arrow, Serde, or similar analytical/streaming frameworks.
• Familiarity with or eagerness to learn C++ for contributing to ClickHouse's multi-language ecosystem and core engine optimizations.
• Understanding of TCP/IP, HTTP protocols, and network optimization techniques.
• Experience with data serialization formats (Arrow, Parquet, Avro) and their Rust implementations.
• Knowledge of distributed systems patterns and building fault-tolerant data processing pipelines.
