Overview

Profile match
Rebellions is a South Korean semiconductor company founded in 2020 by former Wall Street quantitative engineers and IBM chip designers to build accelerators specialised for AI inference rather than training. Its ATOM processor targets efficiency per watt in data centre inference, and the follow-on REBEL design uses chiplet packaging to scale to large language model workloads. The company merged with Sapeon Korea, the AI chip unit of the SK group, to consolidate the domestic effort against foreign GPUs, becoming South Korea's first AI semiconductor unicorn and working closely with SK Telecom, KT and Samsung Foundry.
Responsibilities and Opportunities
- 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
Key Qualifications
- 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
Ideal Qualifications
- Interest or hands-on experience in modern Linux kernel memory management trends, including the use of Rust for Linux (e.g., utilizing ‘zerocopy’ or safe abstractions for device drivers)
- Previous experience in GPU, NPU, or other complex accelerator device driver development (e.g., DRM subsystem)
- Understanding of device memory communication protocols and handling zero-copy data movement between user-space and kernel/hardware
- Over 5 years of experience in kernel driver development and performance tuning for large-scale systems
