## Description

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.
SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.
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.
Responsibilities
- Rearchitecting the control plane / scheduler to support 1 million concurrent VMs per cluster.
- Building a ublk block device that can dedupe, lazy load, and efficiently snapshot VM data.
- Designing an egress proxy and network isolation to securely filter, monitor, and route agent traffic.
- Designing resilient systems that can operate across a mixture of cloud and on-premise datacenters.
Basic Qualifications
- Bachelor's degree in computer science, engineering, math, or scientific discipline; OR 2+ years of professional experience building software in lieu of a degree
Preferred Skills and Experience
- You have deep experience with building compute orchestration (e.g. Kubernetes, Mesos).
- You have built and operated large fleets of VMs / isolated sandboxes.
- You have experience with the Linux kernel and virtualization technologies.
- You enjoy thinking about infrastructure primitives that future agents will require.
