As a Drivers & Virtualization Engineer, you will own the host-facing software boundary. Your mission is to ensure our hardware is accessible, secure, and performant across diverse environments-ranging from bare-metal deployments to complex virtualized and multi-device cloud infrastructures. You will focus on building robust kernel-level interfaces where correctness, isolation, and long-term operational safety are paramount.
Responsibilities
Develop and maintain high-performance Linux kernel drivers for proprietary accelerator.
Implement communication protocols and virtual device interfaces to bridge hardware and software.
Manage low-level hardware interactions including PCIe, DMA, MMIO, and interrupt handling.
Enable seamless virtualized access to accelerators using QEMU and KVM.
Design and implement robust device sharing, passthrough, and isolation mechanisms.
Ensure the security of accelerator operations through strict memory protection and resource isolation.
Debug complex failures that span the entire stack: from hardware and kernel to hypervisor and guest OS.
Support the scaling of our architecture from single-device setups to large-scale multi-device deployments.
Requirements: Masters or PhD degree in Computer Science, Computer Engineering, or a related field.
Deep knowledge of OS internals, particularly kernel memory management and I/O paths.
Strong understanding of memory safety requirements in kernel space.
Proven hands-on experience in Linux kernel driver development and kernel modules.
Solid understanding of virtualization fundamentals (KVM, hypervisors).
Practical experience with emulation frameworks, specifically QEMU internals or custom device models.
Familiarity with hardware-level protocols: PCIe, DMA, MMIO, and IOMMU.
Language: English at a proficient level. French is a plus.
This position is open to all candidates.
