• Leading security design reviews for critical systems including model serving environments, multi-tenant isolation, authentication and authorization frameworks, and data handling pipelines
• Driving AI-specific security initiatives including defense against prompt injection, model extraction, adversarial inputs, data poisoning, and model supply chain attacks
• Owning compliance readiness for regulatory frameworks (FedRAMP, SOC 2, GDPR), and emerging AI governance standards, partnering with legal and compliance teams
• Developing and maturing the platform's security incident response capabilities including detection, investigation, and remediation playbooks for both traditional and AI-specific threats
• Collaborating with Akamai's broader security organization to align inference platform security practices with enterprise standards and share learnings across product lines
