About the Role

This role focuses on provisioning, configuring, and managing Kafka clusters and Confluent Platform components to ensure high availability, resilience, and security. The position involves implementing and maintaining various Kafka features, governing data policies, and deploying monitoring and automation tools.

Responsibilities

Provision, configure, and manage Kafka clusters (Apache Kafka KRaft or ZooKeeper-backed), Confluent Platform components (Schema Registry, Kafka Connect, ksqlDB, REST Proxy, Control Center), and Confluent Cloud resources.
Ensure high availability (HA) and resilience across multi AZ/region deployments; manage partition replication, min.insync.replicas (ISR), and rack awareness.
Implement and maintain client quotas, broker quotas, throttling, and back pressure strategies.
Plan and execute upgrades/patching with zero/minimal downtime; maintain version currency against EOL and security advisories.
Own backup/restore workflows for metadata, Schema Registry, and Connect configs.
Implement authentication (mTLS/SASL) and authorization (Kafka ACLs, Confluent RBAC).
Enforce encryption in transit and at rest, secret management, secure endpoint exposure, and private connectivity.
Govern topic naming conventions, retention policies, schema evolution rules, and PII handling.
Maintain audit trails and compliance artifacts.
Coordinate vulnerability management.
Deploy and maintain metrics pipelines, logs, and tracing.
Define and monitor SLOs/SLIs.
Analyze broker hotspots, partition skew, large message handling, compaction and retention settings, and tune GC/JVM for sustained throughput.
Implement consumer lag monitoring and alerting with actionable runbooks.
Model workload growth, topic/partition scaling, storage/IOPS, network egress/ingress, and broker sizing.
Optimize Confluent Cloud environments for throughput, cost, and data flow.
Design partitioning strategies to meet throughput targets while balancing consumer concurrency.
Automate cluster and topic lifecycle using Terraform, Helm, GitOps workflows.
Operate and scale Kafka Connect with distributed workers; manage connectors, transforms, and converter settings.
Administer Schema Registry (compatibility levels, subject naming strategies, serializers/deserializers, schema size & references).
Operate ksqlDB and/or Flink for streaming SQL; enforce resource limits and multi tenant governance.
Engineer low latency and secure connectivity across data centers/VPCs/VNETs; manage DNS, TLS SANs, LB configurations, advertised.listeners, and inter cluster networking.

Requirements

5–10 years in platform/SRE/DevOps; 3+ years dedicated to Kafka/Confluent admin in production.
Strong hands on with Apache Kafka internals: brokers, controllers (KRaft), partitions/replication, log segments, compaction/retention.
Confluent Platform: Schema Registry, Kafka Connect, ksqlDB, Control Center, Confluent REST APIs; or Confluent Cloud admin (environments, clusters, RBAC, audit logs, networking).
Proficiency with Kafka CLI tools and AdminClient usage; deep knowledge of ACLs, quotas, transactions, idempotent producers, and exactly once semantics scenarios.
Prometheus/Grafana, JMX exporters, alerting systems (Alertmanager etc).
JVM tuning, Linux performance (NUMA, file descriptors, page cache, disk/RAID, XFS), and network tuning (TCP buffers, MTU, jumbo frames where applicable).
Linux administration (systemd, journald, kernel params), virtualization/containers (Docker, Kubernetes).
Cloud networking (VPC/VNET peering, transit gateways, PrivateLink/Private Service Connect), multi region architectures.
