Node.jsLinuxFPGAElectrical Engineering
About the role
- Successful candidates for these roles will be responsible for delivering performant and functionally accurate silicon for MatX products across compute, memory management.
- Each engineer on this team has a primary focus area, but ownership of overlapping components is shared, and you should expect (and want) to venture across the stack.
Responsibilities
- 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
- Test and validate early chip features on pre-silicon platforms: software simulation, emulation, and FPGA environments - often as the first software to ever touch a new hardware feature
- Drive first-silicon bring-up side by side with hardware, BMC firmware, and platform engineers, debugging issues that span RTL, firmware, kernel, and userspace
- Profile and optimize the host I/O path: PCIe throughput, DMA efficiency, interrupt latency, and OS overheads
- Deliver unit and regression tests for kernel and library components
- Influence next-generation chip architecture by feeding software requirements back into silicon design
- Share ownership of adjacent components with teammates - e.g., contributing to the chip initialization and telemetry daemons that build on your driver interfaces
- Commute On Us For those commuting up to 1 hour, put your rideshare cost on our company card and reclaim the drive-time to get work done!
Requirements
- Experience with pre-silicon validation environments (simulation, emulation, FPGA prototyping)
- Familiarity with SR-IOV, dma-buf, peer-to-peer PCIe, or VFIO
Nice to have
- Expose driver-level device state and error information in ways the platform telemetry and management layers (and, where relevant, the BMC) can consume
- 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
Skills
- What MatX Is Building
- High-speed connectivity and other key technologies.
