Senior Software Engineer, Agent Policy Fabric

The Agentic Safety Engineering team is building Agent Policy Fabric (APF), an enterprise governance layer for AI agents. APF combines signed policy, runtime verification, policy projection, credential mediation, and audit records to help govern the actions agents take across enterprise systems. We are looking for a Senior Software Engineer to help turn the APF proof of concept into diligent production software. You will build, implement, test, and operate features in policy verification, runtime integration, or conformance testing. Working with experienced platform and security engineers, you will own a defined feature or subsystem and help ensure that policy decisions are accurate, integrations are reliable, and failures are handled safely! Join us! What You'll Be Doing: Build policy-verification features: Implement components of the Runtime Policy Verifier and authorization APIs, including signed policy validation, freshness and revocation checks, rollback protection, and binding decisions to the correct subject and runtime context, following reviewed security contracts. Implement policy projection: Translate canonical APF policy into runtime-specific rules and adapter constraints. Handle unsupported policies and partial updates safely so runtimes admit work only when the required policy has been accepted. Develop runtime integrations: Work with OpenShell and other runtime engineers to implement and test agreed interfaces for policy consumption, runtime context, admission d
