You will ensure that every Action Point™, AI decision, and workflow is securely authorized, auditable, and aligned with human intent. This role sits at the intersection of frontend, backend, and cloud security. Everything you build is expected to be revenue-ready and enterprise-grade. Key Responsibilities Identity & Authentication - Implement and manage authentication using Clerk across frontend and backend. - Design RBAC and permission models aligned with human-led decision workflows. - Implement secure session handling, JWT validation, and token lifecycles.

Agent & AI Action Security - Design and implement identity and permission models for AI agents, tools, and automated workflows. - Define and enforce capability-based permission scopes for agents (what actions they can take, on what data, in which contexts). - Implement human-in-the-loop approval gates and policy enforcement points for sensitive or high-impact actions. - Prevent privilege escalation, cross-tenant access, and unauthorized tool or data usage by agents. - Design sandboxing and blast-radius containment strategies for semi-autonomous workflows.
