• Develop relationships quickly and easily with other teams, communicating the complexities of security with a wide variety of audiences, including senior management.
• Manage infrastructure and cybersecurity controls, including enhanced detection and vulnerability capabilities and improved event correlation in large enterprises.
• Lead risk and vulnerability assessments in network, system, and application areas.
• Leverage big data analytics and traditional security event types to identify advanced threats or indicators of compromise.

You Have

• 6+ years of experience administering Elastic Stack, including Elasticsearch, Kibana, Logstash, Beats, or Fleet.
• Experience managing Elasticsearch index lifecycle policies, index templates, and data streams at scale, and building Kibana dashboards, visualizations, and lens-based analytics for security operations.
• Experience with Elastic Security detection rules, alerts, and case management workflows.
• Experience with log ingestion pipeline design, including parsing, enrichment, and normalization across heterogeneous log sources such as network, endpoint, identity, and cloud.

Nice If You Have

• Experience building SOAR‑related automation around Elastic, including webhook actions, connector integrations, or n8n or XSOAR orchestration.
• Experience with Elastic's transforms and runtime fields for creating enriched security datasets and risk scoring indices.
• Experience with RAG architectures or vector search in Elasticsearch for security knowledge retrieval, including TTP lookup and incident context enrichment.
• Experience with Elastic's ML jobs, including for User and Entity Behavior Analytics (UEBA), rare process detection, or anomalous login patterns.
• Experience with Elastic AI Assistant or integration of LLMs into Elastic Security workflows such as natural language querying and alert triage assistance.
• Experience building or fine‑tuning ML models outside Elastic, including Python, scikit‑learn, and PyTorch, for security use cases such as threat detection or lateral movement scoring.
• Knowledge of AI / ML concepts applied to security analytics such as anomaly detection, behavioral baselining, or threat scoring.
