Responsibilities

Strategy and Leadership

• Own the global detection and response strategy, roadmap, and investment plan, tying security outcomes to business risk and customer trust metrics.

• Lead a multi-layer organization across time zones; build a high-performing leadership bench and succession plan.

• Establish governance with clear OKRs, SLOs, and outcome dashboards for executive and board-level visibility.

Detection Engineering

• 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.

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.

• 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.
