This person could potentially support two products:

• Cyber Range – (Colosseum) is an internal cybersecurity platform that allows our internal teams to quickly create and manage cyber testing and training environments through automation. The goal is to make cyber ranges "software-defined," meaning teams can spin up realistic environments for security exercises, threat simulations, and testing without manually building the infrastructure each time.

• Software-Defined Everything (SDE) platform : SDE is a platform designed to automate how mission applications are provisioned, tested, and deployed across cloud, on-prem, and edge environments. The platform enables teams to model and simulate workloads, validate them, and then deploy them to target environments, including AI-enabled and edge computing systems.
