Linux Device Driver Engineer

About Company:

AI chip뿐 아니라 card / server / rack-scale solution 및 proprietary full-stack software까지 함께 개발·제공하고 있습니다.

Key Competencies:

• Develop and maintain Linux device drivers for Rebellions NPUs, building robust foundations for high-performance AI computation
• Design and implement high-throughput, low-latency data transfer solutions and complex DMA operations across PCIe subsystems
• Architect and optimize advanced memory management subsystems, ensuring high stability, zero-overhead, and safe memory handling during host-device communication
• Investigate and adopt modern kernel development paradigms (e.g., safe memory abstractions, Rust-for-Linux concepts) to eliminate memory reference vulnerabilities and maximize DRM subsystem stability
• Design and implement effective communication interfaces with device firmware, developing customized features for seamless hardware integration
• Support and debug complex system-level issues across the software stack and hardware interfaces, optimizing overall system architecture

An Ideal Candidate:

• Bachelor’s or higher degree in Computer Science, Electrical Engineering, Computer Engineering, or related fields
• Minimum of 5 years of experience in general Linux kernel and device driver development (e.g., PCIe, DMA, Network, Storage, DRM)
• Deep understanding of SR-IOV / PCIe device virtualization, IOMMU/SMMU, and DMA (dma-mapping, dma-buf, scatter-gather)
• Strong command of kernel concurrency(locking and ordering (AB-BA), refcounting/object lifetime, RCU, workqueues/kthreads) and the ability to debug deadlocks and use-after-free
• Proven low-level debugging from kernel logs, KASAN/ASAN, and coredumps
• Proficiency in C/C++/Rust
• Strong foundation in handling hardware-software interfaces and interrupt handling
• Excellent communication, analytical, and problem-solving skills
