About the job
What You'll Be Working On
- Develop automation and observability tools to monitor Crusoe’s compute infrastructure, spanning from the kernel to orchestration layers.
- Support and scale the company’s virtualization stack, including technologies such as KVM, QEMU, and other hypervisors.
- Collaborate with Linux kernel and hardware teams to identify and resolve performance bottlenecks, driver issues, and optimize hardware offloads.
- Optimize performance for AI and HPC workloads across CPU, GPU, and DPU/NIC resources.
- Participate in root cause analysis for kernel crashes, hardware-software integration problems, and performance regressions.
- Integrate hypervisor-level enhancements to improve guest VM reliability and workload isolation.
- Tune kernel subsystems such as the process scheduler, NUMA configuration, memory management, and interrupt handling.
- Work closely with platform teams to implement and validate support for emerging compute hardware, including SmartNICs, BlueField devices, and TPUs.
What You’ll Bring to the Team
- 5+ years of professional experience in Compute SRE, Linux system engineering, or compute infrastructure roles.
- Strong proficiency in Linux kernel internals, with exposure to scheduler, memory allocation, and driver subsystems.
- Experience with virtualization architectures and technologies such as KVM, Xen, QEMU, or VMware.
- Familiarity with SmartNICs/DPUs (e.g., NVIDIA CX6/7, BlueField-3) and kernel bypass techniques.
- Expert-level skills in at least one programming language: Go, C or Rust.
- Experience with system-level debugging, including kdump, kexec, and kernel panic analysis.
- Proficiency in Infrastructure as Code tooling and CI/CD practices for bare-metal or cloud infrastructure.
- Strong understanding of compute scheduling, resource management, and high-throughput networking.
Bonus Points
- Experience porting or maintaining custom Linux distributions or kernels for specific platforms.
- Exposure to AI model infrastructure and workload orchestration across GPU clusters.
- Contributions to Linux kernel, KVM, or other low-level infrastructure projects.
