Skills And Experience Master’s 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. Responsibilities Develop and maintain high-performance Linux kernel drivers for Arago’s 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. Pay and benefits Competitive cash compensation, with final package based on location, experience, and the pay of team members in similar positions. Meaningful stock option plan offered at the earliest stage of the company (included in the majority of full time offers). Relocation
