Systems Software Engineer PCIe Device Driver

You will develop and maintain Linux PCIe device drivers and kernel modules. You will optimize DMA, IOMMU, interrupts, and BAR mapping; build user-space libraries and APIs; collaborate on PCIe I/O pipelines; and design efficient memory management and zero-copy transfer paths.

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 for high-performance data paths
• Collaborate with hardware and firmware teams on end-to-end PCIe I/O pipelines
• Design efficient memory management and zero-copy data-transfer paths

Requirements

• Understanding of Linux kernel internals and memory management
• Experience developing C kernel modules
• Knowledge of PCIe protocol and subsystem architecture
• Experience with kernel debugging tools including gdb, ftrace, and perf
