As AI agents move from simple chatbots to autonomous workloads with access to sensitive enterprise data, the industry lacks a standard for Identity, Authentication, and Governance. Our platform does not stop at application code. It also creates and manages the secure cloud infrastructure in which AI-agent systems are deployed and operated. That makes infrastructure design a core product capability, not a supporting function. This role will lead the design and implementation of the multi-cloud platform that supports customer environments, secure deployment patterns, cloud networking, and production guardrails. It is a hands-on principal engineering role for someone who wants to build the underlying infrastructure that makes secure AI-agent deployment possible at scale.

Own data models, service contracts, validation logic, and service-to-service interactions for core platform workflows. Work on integrations with cloud services, identity systems, and platform components that support secure runtime environments. Improve observability, error handling, test coverage, deployment safety, and production support for backend services. Collaborate
