Job Description

We're looking for a Principal Software Engineer with 8+ years of experience to lead the design and implementation of our host-side PCIe drivers. You will architect and build a high-performance, multi-OS driver solution that supports complex hardware topologies. This role requires deep expertise in low-level system software, cross-platform driver development, and a proven ability to lead technical initiatives.

Key Responsibilities 🛠️

• Multi-OS PCIe Driver Development: You will serve as the technical lead for designing and implementing high-performance PCIe kernel-mode drivers for both Linux and Windows. Your work will be crucial in developing a robust architecture that supports multiple endpoints across multiple cards and ensures reliable communication.
• User-Space Library & PyTorch Runtime Integration: Architect and implement a high-performance user-space library that directly interfaces with the kernel-mode driver. This library will be the primary communication channel for the PyTorch runtime, providing a seamless and efficient way to send commands and data to the device.
• PCIe Switch Management: Architect and implement the driver logic to support complex hardware topologies involving multiple PCIe cards connected over an external PCIe switch. You'll be responsible for the sophisticated driver logic required to identify and correctly set up the PCI device address for each individual PCIe device on each card.
• Performance & Reliability: Take ownership of the driver's performance, ensuring high-bandwidth and low-latency data transfers. You'll be responsible for the stability and reliability of the system, designing robust error handling and recovery mechanisms.
• Cross-Functional Leadership: Collaborate closely with hardware, firmware, and user-space software teams. You will be a key voice in defining system-wide architectural requirements and ensuring a cohesive, end-to-end solution.
• Mentorship: Guide and mentor other engineers, providing technical direction and fostering a culture of excellence in low-level software development.

Required Qualifications 🧠

• Experience: 7+ years of hands-on experience in low-level system software development.
• Kernel-Mode Expertise: Deep, hands-on experience designing and developing kernel-mode drivers for both Linux and Windows.
• Linux: In-depth knowledge of the Linux kernel driver model and debugging tools.
• Windows: Extensive experience with the Windows Driver Kit (WDK) and the WDM/KMDF driver models.
• PCIe Architecture: Expert-level understanding of the PCIe specification, including complex topologies involving switches, bus numbering, and device address management.
• Problem-Solving: Exceptional debugging skills and a proven track record of solving the most challenging system-level problems.
• Leadership: Demonstrated ability to lead technical projects and mentor engineers.
• Education: Bachelor's or Master's degree in Computer Science, Electrical Engineering, or a related field.
• Linux: In-depth knowledge of the Linux kernel driver model and debugging tools.
• Windows: Extensive experience with the Windows Driver Kit (WDK) and the WDM/KMDF driver models.
