XDR/EDR experience: Microsoft Defender, CrowdStrike, Cortex, or SentinelOne; hands-on NDR knowledge, such as Vectra AI or Corelight. Cloud security telemetry, particularly Azure; threat intelligence integration and awareness of AI-driven SOC tools. Customer-facing consultancy skills and clear technical communication. Duties & Responsibilities Build and tune SIEM/XDR detections using KQL or equivalent languages, aligned to MITRE ATT&CK and real-world threats. Map and normalise log sources, assess coverage, and close telemetry, logging, and enrichment gaps. Build SOAR automations, integrations, response workflows, and documented incident playbooks for SOC teams. Turn threat intelligence and operational lessons into stronger detections and automations. Own detection-as-code pipelines, structured use case development, and versioning. Advise customers, lead workshops, and deliver clear detection strategies, use case catalogues, and recommendations for all stakeholders. Partner with onboarding, engineering, and SOC teams to integrate practical, operationally aligned content. Evolve reusable content, delivery standards, and automation patterns through lab testing and validation.
