About the role

The Integrations Ecosystem org is the bridge between ClickHouse and the rest of the data world.
Our scope spans low-level database drivers, ingestion and CDC pipelines, data framework integrations, and BI connectivity - ensuring ClickHouse feels native in whatever stack our users already have.
This role sits on the Language Clients team, which provides the JVM foundation that everything else in the ecosystem is built on.

As a Senior Software Engineer on Language Clients, you'll be a technical owner of ClickHouse's Java client and JDBC driver, the foundation that our own Connectors team and a long list of external
Your primary users are engineers: the Connectors team building ClickHouse connectors for Kafka, Flink, Spark, and others, and the broader JVM ecosystem (data ingestion tools, BI platforms, data visualizations) that consumes the driver directly.
Your job is to make sure they have a fast, reliable, well-designed foundation and to treat their feedback as the signal for where the driver goes next.
Own the Java client and JDBC driver end-to-end: roadmap, API design, performance, release engineering, and partner-facing support.
Drive throughput and latency work across the client and ClickHouse server
Partner day-to-day with the Connectors team as an embedded internal customer: understand what their connectors need from the driver, and ship it.
Engage directly with external partners across data ingestion, and data visualization on interoperability, regressions, and roadmap alignment.
Hands-on experience building or substantially extending a library that other engineers depend on. You understand that API design compounds, and that a breaking change in a widely used library is a very different thing from a breaking change in an application.

5+ years of software engineering experience with a significant portion focused on data-intensive systems: drivers, SDKs, ingestion, CDC, streaming, or analytics.
In your first year you can expect to:

Working knowledge of JDBC internals, ADBC, or Arrow / Arrow Flight SQL.
Experience designing or evolving wire protocols, or contributing to a widely-used network client.
Prior contributions to open-source data infrastructure (Kafka, Spark, Flink, dbt, Debezium, Iceberg, or similar).
Working knowledge of ClickHouse or another columnar/OLAP engine.
The actual compensation may be higher or lower than the amounts listed, and the ranges may be subject to future adjustments.
