You will be tasked with building the secure "sandbox" where autonomous agents live, ensuring zero-trust connectivity and managing the specialized data stores that power agentic reasoning. You will lead the setup of the AWS production environment and the implementation ofFirecracker MicroVMs to provide isolated, ephemeraly runtimes for agents. You are the guardian of the platform's "Egress Controls," ensuring that while agents can reason over proprietary data, they can never exfiltrate it.
