About the Role
As a Software Engineer on Compute Infra at SpaceXAI, you'll build the sandbox infrastructure to give every agent their own VM. These VMs power coding agents, Grok Bot, reinforcement learning, and more. We operate one of the largest set of sandbox clusters in the world, at millions of CPU cores, across third- and first-party datacenters. You'll own developing a cloud for agents, including the virtualization layer (Firecracker and Cloud Hypervisor microVMs), control plane scaling, and the networking/connectivity layer on top.

About SpaceX
SpaceX is an American aerospace manufacturer and space transportation services company founded in 2002 by entrepreneur Elon Musk. The company designs, manufactures, and launches advanced rockets and spacecraft. SpaceX has developed the Falcon 1, Falcon 9, Falcon Heavy, and Dragon spacecraft. The company was founded with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX has achieved several milestones in spaceflight, including the first privately-funded liquid-propellant rocket to reach orbit, the first privately-funded company to send a spacecraft to the International Space Station, and the first privately-funded company to send a human-rated spacecraft to orbit.
