Network & Micro-Segmentation Architecture: Translate Zero Trust Network Access (ZTNA) principles into operational controls, including network micro-segmentation, secure access models, and perimeter defense strategies.
Incident Readiness for AI-Driven Threats: Support the evolution of incident response playbooks to defend against AI-accelerated threats, automated attack vectors, and machine-speed exploitation.
Cross-Functional Collaboration & Metrics: Define key performance indicators (KPIs), facilitate tabletop exercises, and partner with security operations, cloud engineering, and technical leads to embed security controls into day-to-day operations.
Qualifications
Cyber Security Seniority: 7–10+ years of dedicated experience in cyber security, with a strong background in CSIRT and Security Operations Center (SOC) environments (Strictly Required).

Incident Communication & Governance: Demonstrated success authoring executive briefings, incident reports, and developing incident response playbooks, policies, and standards (Strictly Required).
Hands-On Zero Trust Delivery: Proven hands-on experience implementing Zero Trust technologies, conducting security gap analyses, and operationalizing Zero Trust models (Strictly Required).
Identity & Network Security Controls: Direct expertise with identity security controls (MFA, Conditional Access, RBAC, PAM/PIM, Entra ID) and Zero Trust network principles (segmentation, ZTNA) (Strictly Required).
Nice-to-Have Assets:
Prior cyber security experience within a public sector environment.
Professional certifications such as CISSP, CISM, GIAC, or Azure Security Engineer.
