What you'll do

As a Drivers & Virtualization Engineer, you will own the host-facing software boundary of Arago's accelerator. 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.

Required 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 bonus and coverage of moving expenses for relocation within 20 minutes of the company's location.

• Healthcare coverage (including family-friendly options), pension contributions, professional development support, and 25 days of PTO, in addition to public holidays.

• Ownership of a key technical domain, with significant vertical and/or horizontal growth opportunities, based on performance and individual drive.

• Reimbursement of 50% of the public transport subscription fee.

• A high-paced, multicultural (with 10 nationalities), and engineering-led environment.
