• Design and implement security controls that protect AI agents, machine identities, service accounts, and other non-human identities.
• Support governance frameworks and security controls for AI-enabled technologies, agentic workflows, and Model Context Protocol (MCP) integrations.
• Develop and enhance privileged access management capabilities that provide strong authentication, authorization, and access governance controls.
• Partner with cybersecurity architecture, infrastructure, engineering, and platform teams to embed security controls into enterprise technology solutions.
• Design and implement automated access certification, approval, attestation, monitoring, and audit workflows.
• Maintain comprehensive audit trails and control evidence supporting regulatory, risk, governance, and compliance requirements.
• Analyze emerging risks associated with AI technologies and recommend appropriate security controls and mitigation strategies.
• Contribute to security architecture reviews and provide technical guidance on identity security best practices.
• Support continuous improvement initiatives focused on automation, operational efficiency, and risk reduction.
• Share knowledge and mentor less experienced team members while contributing to team objectives and security program maturity.

Required Qualifications:

• Experience integrating IAM platforms such as Entra ID, Okta, CyberArk, or similar technologies into modern application architectures and cloud-based platforms.
