Build realistic enterprises. Connect applications, networks, identities, and third-party services across Azure, AWS, GCP, and on-premises systems, including realistic user activity and security telemetry. Make environments repeatable. Build reusable infrastructure, images, and self-service automation to provision, validate, reset, and retire complete environments. Enable AI training and evaluation. Deliver interfaces for agent actions, observations, and evidence collection so teams can reliably compare model, agent, and harness changes. Engineer for safe scale. Support concurrent experiments with strong isolation, synthetic data, health checks, recovery, and cost controls. Own capabilities end to end. Partner with security researchers and AI engineers to ship dependable systems, resolve cross-stack challenges, and mentor engineers.
