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.

Responsibilities

  • 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.

Requirements

  • 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:

Nice to have

  • 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.
  • If you have any questions or comments about compensation as a candidate, please get in touch with us at paytransparency@clickhouse.com.
