About the role

Key responsibilities & impact

Drive Systemic Root Cause Analysis (RCA): Lead deep-dive investigations into recurring vulnerability classifications to identify systemic design flaws.
Lead Investigative Threat Research & Pivoting: When a compromised asset is identified, perform technical correlation to determine if related infrastructure, subnets, or technically congruent stacks are also exposed.
Identify Shared Technical Vulnerabilities: Leverage external intelligence and internal data correlation to identify assets that mirror the technical configuration and exploitability of originally compromised targets, providing Defense teams with an expanded scope for remediation.
Translate Offensive Intelligence: Partner with Red, Purple, and Pen Test teams to translate 100% of validated TTPs into actionable mitigation strategies mapped to the MITRE ATT&CK framework.
Author Security Blueprints & Guardrails: Draft a suite of "Secure-by-Default" hardening guides and templates, using trend data to define high-end technical security standards.
Advocate for Preventive Controls: Provide high-level technical guidance to inform the development of tactical playbooks and lower-level hardening guides, ensuring security is baked into the foundation of the network.
Verification & Validation (V&V): Perform rigorous post-remediation testing to confirm that security fixes are implemented correctly and function as intended.
