• Provide senior-level support for user provisioning, deprovisioning, and access review processes.
• Configure and optimize SSO, MFA, conditional access, and federation services.
• Analyze access-related security events and support investigations in partnership with the SOC and other security teams.
• Design and maintain role models, entitlement structures, and privileged access workflows.
• Review and guide application and infrastructure integrations with IAM platforms using established standards.
• Lead automation efforts to reduce manual work and improve reliability across IAM and security processes.
• Contribute to and review security documentation, policies, standards, and audit materials.
• Partner with engineering and business teams to ensure secure access design for new and evolving technologies.
• Implement and support IAM capabilities across AWS, Okta, Entra ID, Active Directory, and SaaS platforms.
• Design and manage service accounts, application identities, and workload authentication models.
• Implement and support secrets management using KMS, Vault, and cloud-native solutions.
• Integrate IAM logging with SIEM platforms and help refine identity-focused detection and monitoring.
• Support audits, access certifications, and remediation of security findings.

Job Qualification

• 4 to 6 years of experience in information security, security engineering, or related technical roles.
• Strong hands-on experience with IAM platforms such as Active Directory, Entra ID, Okta, SailPoint, CyberArk, or similar technologies.
• Deep understanding of authentication and authorization concepts and protocols including SAML, OAuth, OIDC, LDAP, and Kerberos.
• Experience with scripting or automation using PowerShell, Python, or similar languages.
• Practical experience with identity governance, privileged access management, and access review processes.
• Solid understanding of security fundamentals, cloud security concepts, and zero trust principles.

Preferred * Experience supporting security or IAM in large, distributed, or hybrid environments.
