- Apply enterprise identity and access management practices, including SSO, SAML, OAuth 2.0, OIDC, SCIM, RBAC, and JWT-based authentication.
- Conduct security testing of AI agents and integrations, including unauthorized access, privilege escalation, prompt injection, token misuse, and tool-abuse scenarios.
- Build repeatable validation and evaluation frameworks to assess agent behavior, security, and reliability.
- Configure custom agents, GPTs/assistants, tool integrations, and multi-agent workflows.
- Troubleshoot complex integration and access issues while partnering with engineering and security teams.
- Establish best practices and technical standards for the safe and scalable adoption of AI coding agents.
Required Qualifications
- 5+ years of hands-on experience administering, configuring, and troubleshooting GitHub Copilot and/or OpenAI Codex in production environments.
- Demonstrated experience with enterprise AI coding tool governance, access controls, repository permissions, model configuration, and usage policies.
- Experience building and securing MCP servers, including scope management, authentication, authorization, identity propagation, and credential security.
- Strong understanding of enterprise IAM concepts, including SSO, SAML, OAuth 2.0, OIDC, SCIM, RBAC, and JWT/bearer tokens.
- Strong AWS experience, particularly with IAM, Bedrock/Bedrock Agents, ECS, Lambda, API Gateway, CloudWatch, Secrets Manager, and VPC/networking.
- Strong Python programming skills, including REST API development, automation, integrations, and testing frameworks.
- Experience with AI agent security testing, including prompt injection, unauthorized tool access, privilege escalation, and credential-handling vulnerabilities.
- Experience developing or configuring custom AI agents, assistants, tool integrations, and multi-agent workflows.
- Ability to work independently, resolve complex technical issues, and establish enterprise implementation standards.
- Bachelor's degree in Computer Science, Information Systems, or a related field.
Preferred Qualifications
- Bash and shell scripting experience.
- PowerShell scripting experience.
- Dedicated AI security testing or AI red-teaming experience.
- Experience supporting large-scale enterprise developer tooling and cloud security initiatives.
