We are looking for a Senior Security Software Engineer to implement the baseline Cedar policy library and policy authoring standard for our Enterprise Agent Development Platform.

• Design parameter-level access control patterns for agent tooling
• Establish governance standards for policy authoring across engineering teams
• Collaborate with platform and security teams to enforce consistent access control practices
