О компании и продукте

• The ClickPipes - Database Integrations team builds the platform that enables real-time data replication from databases into ClickHouse at petabyte scale.
• As a member of this team, you will be solving complex database-related challenges and distributed systems problems, such as understanding database internals to optimize snapshotting strategy, handling schema evolution during live replication, managing data type compatibility across systems, maintaining low end-to-end latency under unpredictable loads, and leveraging durable execution frameworks to ensure data consistency over unreliable networks. We work in the open — our database integrations are built on PeerDB https://github.com/PeerDB-io/peerdb, an open-source CDC platform we actively maintain and contribute to.
• ClickPipes for Postgres now supports failover replication slots https://clickhouse.com/blog/clickpipes-postgres-failover-replication
• MongoDB CDC to ClickHouse with Native JSON Support https://clickhouse.com/blog/mongodb-cdc-clickhouse-preview

Задачи

• Build data-intensive systems
• Design and develop high-throughput integrations with databases (Postgres, MySQL, MongoDB), data lakes (Iceberg, Delta Lake), and data warehouses (BigQuery, Snowflake)
• Handle edge cases in real-world production scenarios: unconventional database setups, internals of data types, database upgrades/failovers, large transactions, etc
• Design integration solutions to enable users to fully harness ClickHouse's performance and throughput
• Own end-to-end reliability
• Debug complex issues in production leveraging runtime diagnostics (e.g. pprof, parca) and observability tools (e.g. metrics, logging, tracing)
• Build and improve infrastructure and tools to increase system reliability, reduce incident response time, and simplify/automate operations
• Write clear documentation, both publicly and internally
• Participate in on-call rotation
• Drive product innovation
• Work directly with customers to understand integration requirements and discover gaps in existing product
• Collaborate cross-functionally with internal teams to ensure operational efficiency

• Cloud-native experience deploying and operating services on at least one major cloud platform (AWS/GCP/Azure)
• Practical experience with Kubernetes
• Strong problem solver and solid production debugging skills
• Clear communication in writing (design docs, code review) and verbally (technical discussions, customer calls, incident response)

Будет плюсом

• Experience with database replication technologies (CDC, logical replication)
• Experience with durable execution frameworks (Temporal)
• Experience with data formats and protocols (Avro, Parquet, Protobuf)
• Experience with modern data processing frameworks (e.g. Kafka, Spark, Flink)
• Experience with maintaining/contributing to open-source software
• WHY JOIN US
