- Continuously reduce false positives and missed detections through quality gates, purple teaming, and regression testing pipelines.
Incident Response and Operations
- 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.
Threat Intelligence and Hunting
- 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.
Platform, Data, and AI Enablement
- Partner with Trust Engineering to evolve the security data platform; ensure reliable, privacy-aware telemetry and lineage for detections and analytics.
- Leverage ML/LLM-assisted detections, triage, and summarization responsibly; define evaluation frameworks and human-in-the-loop controls.
Risk, Compliance, and Partnering
- Align with Product Security, Corporate Security, Governance/Risk, and Security Assessments to close systemic risks and meet customer/regulatory commitments.
- Represent DnR in executive forums, customer escalations, and external audits; build trust through transparency and evidence.
