Original job description

About the team

The Integrations Ecosystem org builds the drivers, SDKs, connectors and BI integrations that make ClickHouse feel native in any stack. The Language Clients team maintains the official clients for Python, JavaScript, Java, Go, Rust, C++ and C#, plus the ODBC, JDBC and ADBC drivers. We're small, senior and remote across North America and EMEA.

The role

We're looking for a product-minded engineer to own the ClickHouse .NET client. You'll decide what the client should do by talking to the developers who use it, reading the issues and the telemetry, and listening to the community. Then you'll build it, with deep .NET expertise, and measure whether it worked. Your scope is the SDK and what builds on it: ADO.NET, Dapper and Entity Framework Core users, and the tools and integrations that depend on your client.

What you'll do

Know who uses the client and what they're trying to do. Define what good looks like (time to first query, error clarity, adoption by key integrations), measure it, and let that drive the roadmap.
Be the voice of ClickHouse for .NET developers. Speak at .NET conferences and meet-ups, and write the posts, tutorials and samples that developers and AI assistants find when they search for how to use ClickHouse from .NET (SEO and GEO). Answer questions where the community asks them.
Own the .NET client and its ecosystem: the client, the EF Core provider and ORM integrations, NuGet releases and support. Evolve it without breaking the people who depend on it.
Review and co-maintain other clients, and take part in cross-client decisions on types, errors and protocol features.
Bring what .NET and Windows users need to the ODBC driver, since that's how many Windows and BI tools reach ClickHouse. If you write C++, contribute to it directly.
Bring written proposals about where we invest next. You set direction rather than wait for it.
Make the client enterprise-ready: TLS and certificate handling, authentication including Microsoft Entra ID, safe credential handling, signed and reproducible packages, and the audit and compliance questions large .NET shops ask before they adopt.
Shape the client for agents as users: an API, docs and error messages an AI coding agent can use correctly on the first try.
Extend our AI development platform, with new workflows for maintaining the clients: consistency checks across languages, issue triage, release checks.

About you

Product-minded. You decide what to build from user evidence, measure whether it worked, and can explain what you chose not to build.
5+ years in software, much of it on data-intensive systems: drivers, SDKs, data access, ingestion or analytics.
Deep C# and .NET expertise: memory management, async and the TPL, Span and pooling, profiling and benchmarking. You reason about throughput and latency down to allocations and bytes on the wire, and you prove it with tests and benchmarks.
Fluent in C#, and productive in at least one more of our client languages (Python, JavaScript, Java, Go, Rust, C++). You'll review and co-own across clients, not only .NET.
You've built or substantially extended a library other engineers depend on, and shipped NuGet packages across .NET Framework and modern .NET. You treat breaking changes accordingly.
Fluent in .NET data access (ADO.NET, Dapper, EF Core) and at home in the wider .NET ecosystem: ASP.NET Core, Aspire, NuGet.
Security-minded. You've shipped a library into enterprise environments and know what security, compliance and procurement teams look for in a dependency.
Enthusiastic about working in public. You've given talks or written technical content, or you're keen to, and you see it as part of the job rather than a distraction from it.
Thoughtful use of AI development tools, with the judgment to review what comes out.
Clear writing. Most coordination happens in design docs, PRs and RFCs.

Nice to have

ClickHouse, especially its type system, or another OLAP engine.
C++ and ODBC driver internals.
Building or maintaining an ADO.NET or EF Core provider.
Open-source contributions to .NET or data infrastructure.
Experience designing SDKs, docs or error messages with AI coding agents as the consumer.
Protocol or wire-format work on a database driver or network client.
