Job summary

CoreWeave is seeking a Senior Software Engineer for HAVOCK's Runtime & Virtualization team to design and build the execution environment powering the AI platform. You will work across the Linux kernel, KVM/QEMU, container runtimes, GPU drivers, and Kubernetes, solving hard problems with hardware and software integration.

You’ll develop secure sandboxed runtimes for GPU workloads, extend virtualization for new hardware, and build tooling to observe and diagnose the stack from kernel to cloud.

Qualifications

• 5+ years building production systems software, platform infrastructure, virtualization, or Linux-based distributed systems.
• Strong Linux systems knowledge including namespaces, cgroups, scheduling, memory management, filesystems, networking, and process lifecycle.
• Experience with virtualization technologies such as KVM, QEMU, VFIO, virtio, Kata Containers, KubeVirt, Firecracker, or gVisor.
• Experience building or operating Kubernetes platforms and container runtimes at scale.
• Strong systems programming skills in Go, Rust, C/C++, or a combination thereof.
• Comfortable debugging production failures spanning hardware, OS, container runtimes, virtualization, and distributed infrastructure.
• Experience profiling and optimizing system performance using tools such as perf, eBPF, ftrace, bpftrace, flame graphs, or crash analysis.

Responsibilities

• Design secure execution environments using containerd, runc, gVisor, Kata Containers, KubeVirt, and KVM/QEMU.
• Build GPU-aware runtime infrastructure supporting VFIO, Kata, NVIDIA GPU Operator, and PCIe passthrough for multi-tenant AI workloads.
• Improve Linux kernel and hypervisor performance through optimization of scheduling, memory management, I/O, NUMA locality, and virtualization primitives.
• Debug complex interactions across Linux, KVM, GPU drivers, firmware, and Kubernetes when workloads don't behave as expected.
• Develop observability and debugging tooling using eBPF, perf, tracepoints, and kernel tracing infrastructure.
• Improve container and VM startup performance, resource isolation, and runtime efficiency for latency-sensitive AI inference and training workloads.
• Extend virtualization infrastructure supporting virtio devices, IOMMU, SR-IOV, mediated devices, nested virtualization, and hardware passthrough.
