Requirements

Proven deep knowledge of hypervisor internals (e.g., KVM, QEMU, Xen, or other bare-metal hypervisors), including CPU virtualization (VT-x/AMD-V), memory virtualization (EPT/NPT, MMU), and I/O virtualization (SR-IOV, virtio)
Strong understanding of virtual machine lifecycle, live migration, snapshotting, and fault tolerance mechanisms
Experience with Linux kernel internals as they pertain to virtualization, including device drivers, memory management

Responsibilities

Design, develop, and optimize core hypervisor components (e.g., KVM, QEMU, or custom solutions) to achieve maximum performance and efficiency for AI workloads, focusing on CPU, memory, and I/O virtualization techniques
Conduct in-depth research into advanced virtualization technologies, exploring novel approaches for isolating and accelerating AI compute, storage, and networking resources; identify and prototype new virtualization features and enhancements to improve density, throughput, and latency
Develop and enhance virtual hardware components and device emulation, ensuring optimal performance and compatibility for specialized AI accelerators (e.g., GPUs, DPUs) within the virtualized environment
Analyze and enhance the performance of the entire virtualization stack, from the hypervisor to the virtualized guest OS, with a specific focus on optimizing for AI/ML workloads, including profiling, bottleneck identification, and implementing low-level optimizations
Diagnose and resolve complex system issues within the virtualization layer; work closely with hardware and guest OS teams to debug and resolve integration challenges
Conduct thorough code reviews to ensure the highest level of software quality, reliability, and security within the hypervisor and virtualization components
Collaborate with other engineering teams, including hardware design, OS development, and AI/ML application teams, to ensure cohesive and integrated product development
