Senior Software Engineer - GPU Sandboxes

Give every AI agent its own GPU Senior Software Engineer – GPU Sandboxes

AI agents increasingly need more than access to a model. They need their own secure compute environment, with real GPU capacity available in seconds.

That is what you’ll help build.

You’ll join a well-funded AI infrastructure company creating isolated, stateful computers that agents can launch and control through an API. The GPU platform is still being built, so you won’t be maintaining someone else’s architecture you’ll be instrumental in defining how it works.

You’ll work deep in the stack across:

KVM/QEMU and GPU passthrough

VFIO, IOMMU and PCIe isolation

NVIDIA drivers and CUDA lifecycle

VM boot paths, snapshots and cold-start performance

GPU-aware scheduling and bin-packing

Health monitoring, failure detection and automated recovery

Security boundaries across shared hosts

They need someone who has built or debugged the underlying virtualization, isolation or device layer in production. KVM/QEMU, Cloud Hypervisor or Firecracker would be ideal, although similarly deep experience with crosvm, Kata Containers, Xen or another hypervisor can translate.

You should also have operated GPUs in production and be comfortable tracing difficult failures across the hypervisor, Linux kernel, drivers and physical hardware.

Go, Rust or C/C++ can all work.

This is rare, high-impact systems engineering with very little existing playbook. You’ll have genuine influence over the architecture, technical direction and foundations of a GPU platform being built for the next generation of AI agents.
