· Lead deep-dive forensic Root Cause Analysis (RCA) for recurring issues and production outages, permanently eliminating recurring problems.
· Manage the health and scaling of distributed clusters (Kafka, Cassandra, Elasticsearch, OpenSearch, Solr), including partition rebalancing and node decommissioning.
· Lead the configuration and tuning of Elasticsearch/OpenSearch and Solr indexing strategies for shard stability and search optimization.
· Develop Terraform modules and Ansible roles to standardize and automate environment management and deployments.
· Maintain the stability of large-scale big data solutions (MapR/Hadoop).
· Participate in a 24/7 on-call rotation and cover weekend interventions as required, with flexibility in business week scheduling.
Requirements:

- Solid experience with Redis, RabbitMQ, and MapR/Hadoop.

- Willingness and availability to take part in a 24/7 on-call rotation.
- Commitment to flexible shift patterns, including weekends, balanced with business week time-off to ensure a sustainable allocation.
