You will join the VirtSat Platform team within Leo Developer Experience. The team owns VirtSat end to end — the simulation service control plane, the virtualization host layer, fidelity of the emulated subsystems, and adoption across Leo.
This role sits on the services side of that boundary. You will own the simulation service: its public APIs, its provisioning workflows, its plugin framework, its canaries and health checks, and its availability and latency posture. A sibling role owns the bare-metal virtualization layer beneath you; you own the contract between them.
