Systems Software Engineer, PCIe Device Driver

About FuriosaAI FuriosaAI builds high-performance, high-efficiency AI compute for the Inference Era. Founded in 2017 by veteran semiconductor and AI algorithm engineers, Furiosa operates globally with offices in Korea and Silicon Valley, along with a compiler-focused R&D lab in Lisbon. Our vision is to make AI computing sustainable, enabling access to powerful AI for everyone on Earth. We solve the AI hardware energy and operational cost crisis at the architectural level, rather than through brute force, building the world's first truly AI-native compute platform to unlock the full potential of artificial intelligence for every enterprise. Key Responsibilities • Develop and maintain Linux PCIe device drivers and kernel modules • Optimize PCIe subsystem behavior including DMA, IOMMU, interrupts, and BAR mapping • Build user-space libraries and APIs enabling high-performance data paths • Work closely with hardware/firmware teams to build end-to-end PCIe I/O pipelines • Design efficient memory management and zero-copy data transfer paths Minimum Qualifications • Strong understanding of Linux Kernel internals and memory management (DMA/IOMMU) • Experience developing kernel modules in C • Knowledge of PCIe protocol and PCIe subsystem architecture • Experience with kernel debugging tools (gdb, ftrace, perf, etc.) Preferred Qualifications • Experience with device drivers for HPC, AI accelerators, or high-speed networking • Background in RDMA/DPDK/SPDK or other high-performance I/O frameworks • Familiarity with NUMA, huge pages, and pinned memory • Upstream contributions or open-source maintainer experience Why Join FuriosaAI The defining bottleneck of the AI era is building the right hardware and software stack to run it at global scale. Furiosa is solving this challenge holistically from the ground up. With our flagship chip, RNGD, in mass production today and our next-generation platform in development with Broadcom, we are proving that full-stack, tensor-native compute is the future of AI infrastructure. This is a pivotal moment to join our team, right as we accelerate our global expansion. At Furiosa, you will: Solve AI’s Most Urgent Challenge.
