Fullstack Software Engineer, Kafka

Tehtävä

We're looking for a Fullstack Software Engineer to join our Kafka Ecosystem team. You'll build features end-to-end: production Python in the platform that orchestrates managed Apache Kafka® services across clouds, contributions to Karapace (our open-source Schema Registry and Kafka REST Proxy), and the React interfaces that put those features in front of users. Your main focus is Python; your reach extends from API design to the UI that ships with it. Extend and maintain Karapace: schema compatibility logic, REST Proxy features such as exposing message headers in produce and consume paths, OpenAPI schema coverage, and Confluent API compatibility Keep the connector ecosystem healthy: upgrades and releases of connectors like Debezium, JDBC, S3, BigQuery, and the OpenSearch® sink, security fixes, and changelogs Participate in design and code reviews, write well-tested code, and help shape technical direction Ship code reliably and often through CI/CD pipelines (Buildkite, GitHub Actions) Investigate and resolve production issues across the stack, from async Python application code down to Linux system behavior Contribute to technical planning within a small team where your input directly shapes the roadmap Own features end-to-end: design the API, build the async Python backend, and wire up the React/TypeScript views in our console Use AI coding tools as part of your daily workflow to speed up development Open-source at the core. A significant part of your work ships publicly as open source. Your name goes on the commits. Deep technical problems. Multi-format schema compatibility, connector lifecycle orchestration at scale, and UIs that make both approachable. Not a typical backend role, and not a typical frontend role either. End-to-end ownership. You design it, build it, ship it, and see users work with it. No handoffs across three teams. Direct impact. The team is large enough to tackle ambitious problems and small enough that your technical judgement still shapes what gets built. Helsinki, hybrid. 3 days in the office per week.
