• Define and govern the AD Delegation and Tiered Administration model to ensure strict adherence to the principle of least privilege across the enterprise.
• Spearhead the onboarding and integration of applications and services with modern identity platforms such as Okta for authentication and authorization.
• Mentor teams on security best practices, driving continuous improvement in identity reliability and lifecycle management.
• Own and publish standards/best practice documentation for identity architecture, administration, and security, serving as the domain's authority.
