• Experience with Non-Human Identity (NHI) lifecycle management in highly dynamic environments.
• Experience working with AI-enabled or automation-heavy systems.
• Experience building AI solutions from start to finish.
• Familiarity with security risks unique to agentic and autonomous systems.
• Ability to reason about non-deterministic AI execution and enforce deterministic security controls.
• Knowledge of MCP security standards and agent runtime authorization.
• Experience with WAFs, API gateways, and edge security controls.
• Familiarity with cloud-native architectures and service-to-service security.
• Strong DevSecOps and Application Security experience.
• Ability to ensure consistent security enforcement across edge, API, service, and AI runtime layers.
• Ability to collaborate effectively with product, platform, AI/ML, and identity teams.
• Strong written and verbal communication skills with the ability to translate complex security concepts into practical guidance.

Responsibilities

• Design and implement security control planes for agentic AI systems.
• Define runtime authorization boundaries for AI agents, including tool-level access controls and least-privilege execution.
• Establish policy enforcement points governing agent behavior before high-impact actions.
• Support human-in-the-loop workflows for sensitive or high-risk AI-initiated actions.
• Design and review identity models for guests, employees, and non-human agent/workload identities.
• Implement or advise on OAuth/OIDC-based delegation and short-lived credential strategies.
• Ensure end-to-end attribution across user, agent, and tool execution chains.
• Secure guest-facing eCommerce flows including search, personalization, cart, and booking.
• Review backend service architectures supporting AI-driven eCommerce experiences.
• Promote agent-safe API patterns including idempotency, preview/apply, rollback, and rate limiting.
• Collaborate on edge security controls including WAFs, bot mitigation, and API gateways.
• Ensure consistent security enforcement from edge to API to service to AI runtime layers.
• Support secure cloud-native, containerized, and sandboxed deployment patterns across Google Cloud, AWS, and Azure.
