Senior Software Engineer II - KORA

We’re not just building better tech. We’re rewriting how data moves and what the world can do with it. With Confluent, data doesn’t sit still. Our platform puts information in motion, streaming in near real-time so companies can react faster, build smarter, and deliver experiences as dynamic as the world around them. The Kora Group Coordinator team is responsible for the core coordination layer that ensures large fleets of consumers and transactional workloads within Kora remain balanced, fault-tolerant, and predictable. We are transitioning from broker-embedded coordination to a standalone, cloud-native service, prompting us to rethink how group membership, state, and metadata are stored, replicated, and recovered at scale. The challenges we address are at the intersection of distributed systems, storage, and cloud operations: designing replicated state machines, managing high-volume, low-latency traffic, handling failures and rebalances gracefully, and achieving all of this across multiple regions and tenants while meeting strict reliability and performance requirements.
