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 C# integrations, you'll be the architect and maintainer of ClickHouse's .NET ecosystem. This role sits at the intersection of high-performance database engineering and developer experience, where you'll craft tools that enable C# developers to harness ClickHouse's incredible speed and scale.

You'll own the full lifecycle of .NET-based integrations—from the core ADO.NET provider and Entity Framework Core integration that handles billions of records per second, to SDKs and ORM adapters that make ClickHouse feel native in C# applications. This isn't just about writing code; you're building the foundation that thousands of .NET developers rely on for their most critical data workloads.

Your work will directly impact how companies process massive datasets, from real-time analytics platforms ingesting millions of events per second to AI and machine learning systems feeding training pipelines and serving feature stores at scale. You'll collaborate closely with the open-source community, internal teams, and enterprise users to ensure our C# integrations set the standard for performance, reliability, and developer experience across the entire .NET ecosystem.

About you:

  • Experience: 5+ years of software development experience focusing on building and delivering high-quality, data-intensive solutions in the .NET ecosystem.
  • C# & .NET Proficiency: Strong proficiency in C# and .NET, including advanced knowledge of memory management, performance tuning, profiling, and debugging with tools like PerfView, dotMemory, or Visual Studio Diagnostic Tools.
  • Data Access Technologies: Deep experience with .NET data access technologies: ADO.NET, Entity Framework Core, Dapper, and other popular ORMs.
  • .NET Ecosystem: Experience with .NET Framework and .NET Core/5+ ecosystems, including cross-platform development, NuGet package management, and modern C# language features.
  • Asynchronous Programming: Expertise in asynchronous programming and concurrent patterns in C#, including Task Parallel Library (TPL), async/await patterns, and high-throughput data processing scenarios.
  • Database Concepts: Strong understanding of database concepts: SQL, data modeling, query optimization, and familiarity with OLAP/analytical databases.
  • Framework Integration: Experience integrating with popular .NET frameworks: ASP.NET Core, Blazor, WPF, and understanding of dependency injection patterns and middleware pipelines.
  • Communication: Outstanding written and verbal communication skills to collaborate effectively within the team and across engineering functions.
  • Open-Source Passion: 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 open-source .NET projects, particularly database drivers, SDK, ORM providers, or data ac
