Job Description
CoreWeave is seeking a highly skilled and motivated Senior Systems Engineer to join our Kernel HAVOCK Team. In this role, you will play a crucial part in the design, development, and optimization of our bare-metal systems from POST through joining a Kubernetes cluster. The team’s primary responsibilities include maintaining a custom Linux kernel, various OS images (Ubuntu-based), the virtualization stack (kubevirt/qemu/vfio), and the container/pod runtime stack (containerd/nydus/kubelet). You will collaborate closely with cross-functional teams, up stack engineering teams, and stakeholders to ensure the successful delivery of highly performant and reliable software solutions.
Kernel Hardware - Acceleration - Virtualization - Operating Systems - Containerization - Kubelet
Our Team’s Stack:
- Linux Kernel (custom build, currently tracking Ubuntu HWE)
- Intel/AMD CPUs, Nvidia GPUs, DPUs, Infiniband and Ethernet NICs
- KubeVirt, QEMU, SR-IOV, vfio-pci
- Ubuntu 22.04
- Containerd, Kubelet
Responsibilities:
- Develop and maintain tooling to build custom Linux kernels and stateless OS images
- Automate packaging of critical components (drivers, microcode, components with out-of-tree patches, etc)
- Serve as a senior point of contact for hardware issue escalation and troubleshooting
- Collaborate with cross-functional teams to define Linux and OS requirements, specifications, and system architecture
- Analyze and optimize the performance of bare-metal and virtualized systems, identify bottlenecks, and propose improvements for enhanced efficiency
Requirements:
- Must have at least 5 years of professional experience maintaining large fleets of Linux servers
- Deep professional experience with troubleshooting and debugging hardware, OS, and kernel issues
- History of improving system efficiency within different subsystems (network, storage, security)
- Strong familiarity with sysctls, cgroups, iommu, init systems, seccomp/apparmor
- Ability to effectively prioritize and communicate proposed features and fixes
- Strong passion for automation, with a commitment to automating processes comprehensively
- Excellent documentation skills and attention to detail
- Strong analytical and problem-solving abilities
Nice-to-haves:
- Experience with kexec, kpatch, kdump
- Experience building CI/CD pipelines (GitHub or GitLab)
- Opinions about software version control and team collaboration
- Experience writing software tests
Our compensation reflects the cost of labor across several US geographic markets. The base pay for this position ranges from $130,000/year in our lowest geographic market up to $210,000/year in our highest geographic market. Pay is based on a number of factors including market location and may vary depending on job-related knowledge, skills, and experience.
