Duration: 3+ Months (Extension Possible)

Experience: 15+ Years

Primary Skills: IAM Policy Templates, Cedar Policies

Role Overview:

Seeking an experienced Security Engineer with 15+ years of experience in cloud security and identity management to secure enterprise AI applications on AWS. The role focuses on authentication, reusable IAM policy templates, Cedar-based authorization, and secure access to tools, APIs, and enterprise resources.

Key Responsibilities

  1. IAM Policy Templates & Access Management
    • Design, develop, and maintain reusable AWS IAM policy templates for AI agents and AgentCore infrastructure.
    • Implement role-based access control (RBAC) and least-privilege security principles.
    • Define IAM roles, trust policies, permission boundaries, and resource-based policies.
    • Configure IAM execution roles for AgentCore Runtime and AgentCore Gateway.
    • Develop standardized IAM templates for accessing AWS services such as Lambda, S3, Bedrock, API Gateway, Secrets Manager, and CloudWatch.
    • Automate IAM policy deployment and configuration using Terraform, AWS CloudFormation, or AWS CDK.
    • Conduct IAM access reviews, permission audits, and policy validation.
    • Troubleshoot access-denied issues, role-assumption failures, and authorization misconfigurations.
  2. Cedar Policies at AgentCore Gateway
    • Design, author, test, and deploy Cedar authorization policies using Amazon Bedrock AgentCore Policy.
    • Implement fine-grained authorization for AI agents accessing tools through AgentCore Gateway.
    • Define policies specifying which identities can invoke particular tools, APIs, and operations.
    • Configure policy engines and associate them with AgentCore Gateways.
    • Implement attribute-based access control (ABAC) using identity attributes, roles, scopes, and contextual conditions.
    • Develop policies that restrict sensitive tool operations based on business roles, permissions, and security requirements.
    • Validate Cedar policies against gateway schemas and test permitted and denied access scenarios.
    • Enforce default-deny authorization and prevent unauthorized tool execution.
    • Monitor and troubleshoot authorization decisions and policy evaluation failures.
  3. Security Governance & Compliance
    • Implement security controls for enterprise AI agents and Generative AI applications.
    • Develop security standards for agent identities, API integrations, and access management.
    • Support audit logging, access traceability, and security monitoring using AWS CloudTrail and CloudWatch.
    • Identify and mitigate risks including excessive privileges, credential exposure, unauthorized tool access, and privilege escalation.
    • Conduct security reviews of agent architecture and integrations.
    • Collaborate with AI engineering and DevOps teams to ensure secure production deployments.
  4. Security Automation & DevSecOps
    • Automate security policy deployment through GitHub Actions and infrastructure-as-code pipelines.
    • Integrate IAM and Cedar policy validation into CI/CD workflows.
    • Implement automated security checks and policy compliance testing.
    • Maintain version-controlled security configurations across development, testing, and production environments.
    • Support security incident investigation, access troubleshooting, and remediation.

Required Technical Skills

  • AWS Security: IAM, IAM roles, policies, STS, AWS Secrets Manager, CloudTrail, CloudWatch.
  • Authorization: Cedar policy language, RBAC, ABAC, fine-grained access control.
  • Authentication: OAuth 2.0, OIDC, JWT, AWS IAM authentication.
  • Infrastructure as Code: Terraform, AWS CDK, or CloudFormation.
  • Automation: Python, GitHub Actions, CI/CD security integration.
