• Scale cloud-native detections across identity, data, endpoints, CI/CD, containers, and SaaS leveraging telemetry and modern rule engines.
• Continuously reduce false positives and missed detections through quality gates, purple teaming, and regression testing pipelines.

• Operate a world-class IR function with 24x7 coverage, incident management, executive comms, and customer/regulatory readiness.
• Drive automation and playbooks for rapid containment, eradication, and recovery; blameless post-incident reviews with durable fixes.

• Build an intel fusion capability that translates external and internal signals into prioritized detections and preemptive controls.
• Run hypothesis-driven threat hunting focused on Atlassian-specific TTPs, with measurable findings-to-detection conversion.

• Partner with Trust Engineering to evolve the security data platform; ensure reliable, privacy-aware telemetry and lineage for detections and analytics.
