• Implement and manage data pipelines using tools like Logstash, Fluentd, or custom solutions for efficient data ingestion.

• Define and enforce security policies, including fine-grained access control, encryption, and network segmentation.

• Automate deployment, configuration, and monitoring using Infrastructure-as-Code (IaC) tools like Terraform or CloudFormation.

• Participate in on-call rotations to diagnose and resolve production incidents related to the search platform.


Optimization & Strategy:

• Proactively identify and resolve performance bottlenecks, conducting regular cluster performance testing and optimization, and enhance the search functionality using AI.

• Stay current with the OpenSearch/Elasticsearch ecosystem, new features, and best practices to drive platform innovation.
