Intellia's mission is to help the client with the engineering of a comprehensive software ecosystem for a game-changing Io T product on the margin of innovative consumer experience and cutting-edge technology. Our teams are involved in the engineering of core platform components for best-in-class e Commerce, Digital Marketing and Io T solutions. As an Engineer, you will become a part of Core Architecture Team and be responsible for the architecture, implementation of best practices in our Digital Engineering Enterprise Platform. The Platform is a set of services and internet applications that accelerate the development and delivery of software applications by taking care of common SDLC challenges. The Platform provides access and consumption for engineering teams to a set of services, technologies, practices for their development and for operating their application, ensuring a set of compliance and best practices. Requirements: • AWS Agent Core Policy (Cedar) • Cedar policy language (principals, actions, resources, conditions) • OAuth 2.0 / JWT / MS Entra integration • Policy-as-code patterns • Default-deny authorization models • Audit logging for policy decisions Experience: • 5+ years cloud security or identity engineering • Attribute-based access control (ABAC) design • OAuth 2.0 / JWT token inspection and claims mapping • Enterprise security review (Info Sec, ARB processes) Will be a plus: • AWS Cedar (open source) prior exposure • AWS Verified Permissions or Agent Core Policy early experience • Zero-trust architecture design Responsibilities: Design and implement authorization policies using Cedar and AWS Agent Core Policy. Develop and maintain policy-as-code frameworks for cloud-native and AI-agent platforms. Build and govern Attribute-Based Access Control (ABAC) models following least-privilege and default-deny principles. Integrate authorization systems with OAuth 2.0, JWT, and Microsoft Entra ID. Define and maintain principals, resources, actions, and conditional access policies. Design token validation, claims mapping, and authorization decision workflows. Implement audit logging and traceability for policy evaluation and access decisions. Partner with security, architecture, and platform teams to support enterprise security reviews and governance processes. Contribute to zero-trust security architecture and authorization strategy across distributed systems. Evaluate and adopt emerging AWS authorization technologies, including Cedar and AWS Verified Permissions.
