## About the role

Architect, design, and implement the Linux kernel driver stack for MatX's AI accelerators (PCIe endpoint devices), including memory management, DMA, interrupt handling, and command submission paths Build the low-level userspace libraries that sit directly on top of the driver — ioctl/sysfs interfaces, memory mapping, direct chip access utilities

- BS or higher in Computer Science, Electrical Engineering, or equivalent practical experience, with 8+ years in low-level systems software
- Strong hands-on Linux kernel development experience — you've written and shipped device drivers, ideally for PCIe devices
- Strong C programming skills, comfortable in userspace and kernel space
- Able to read hardware datasheets and register definitions and program a device from them, without waiting for someone to explain the hardware
- Deep understanding of computer architecture and OS internals: MMIO, DMA, interrupts, IOMMU, memory hierarchy, processes/threads, virtual memory
- Experienced debugging complex hardware/software interaction issues with limited visibility
