Description
CoreWeave is The Essential Cloud for AI. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence.
As a Senior Software Engineer on HAVOCK's Runtime & Virtualization team, you'll design and build the execution environment that powers CoreWeave's AI platform. This is fundamentally a Linux systems engineering role where you'll work across the Linux kernel, KVM/QEMU, container runtimes, GPU drivers, and Kubernetes to solve problems that don't have off-the-shelf solutions.
Some of what you'll work on:
- 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.
- Profile production systems and build performance analysis tooling to identify bottlenecks across kernels, hypervisors, container runtimes, storage, networking, and GPUs.
- Collaborate with security, platform, networking, and GPU infrastructure teams to define the next generation of runtime isolation and workload execution.
The base salary range for this role is $182,000 to $242,000. The starting salary will be determined based on job-related knowledge, skills, experience, and market location.
