About the Position

We're looking for an Apache Kafka Platform Administrator who wants real ownership of a modern, business-critical streaming platform - not a generalist who touches Kafka occasionally, but a specialist who wants to go deep.

Why this role is worth your attention:

You own the platform end to end. Cluster architecture, brokers, replication, min.insync.replicas - the durability and availability decisions are yours to make.
Modern Kafka, not legacy. We run KRaft (ZooKeeper-free) - the architecture the ecosystem is moving to. You'll work on where Kafka is going, not where it's been.
The full streaming stack. Kafka Connect and Schema Registry with Avro/JSON - real data-integration and schema-governance work, not just topic management.
Security is yours. You'll design and own the platform's security posture - mTLS, ACLs, hardening.
Deep performance engineering. JVM tuning, retention and cleanup policies, storage and Persistent Volumes - the specialist work that actually separates Kafka engineers from everyone else.
High visibility. When the event backbone matters to the business, you're the person they trust.

Responsibilities

Manage and maintain the Apache Kafka platform
Design and implement Kafka cluster architecture
Ensure data durability and availability
Implement and manage Kafka Connect and Schema Registry
Design and enforce the platform's security posture
