ClickHouse is looking to transform how companies use data by building and maintaining connectors that make ClickHouse accessible to millions of developers and data practitioners worldwide, ensuring seamless integration with existing tools and enabling efficient processing of massive datasets.
Requirements
- Proven experience with the internals of at least one of the following technologies: Apache Spark, Apache Flink, Kafka Connect, or Apache Beam.
- Experience developing or extending connectors, sinks, or sources for at least one big data processing framework such as Apache Spark, Flink, Beam, or Kafka Connect.
- Strong understanding of database fundamentals: SQL, data modeling, query optimization, and familiarity with OLAP/analytical databases.
- Strong proficiency in Java and the JVM ecosystem, including deep knowledge of memory management, garbage collection tuning, and performance profiling.
- Solid experience with concurrent programming in Java, including threads, executors, and reactive or asynchronous patterns.
- Understanding of JDBC, network protocols (TCP/IP, HTTP), and techniques for optimizing data throughput over the wire.
- Prior contributions to open-source projects: actively engaging with the OSS community, advocating for users, and influencing the evolution of the core system through your contributions.
Responsibilities
