Job Description

Were 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
. Youll 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 drivers performance, ensuring high-bandwidth and low-latency data transfers. Youll 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

- 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:
Bachelors or Masters degree in Computer Science, Electrical Engineering, or a related field.Qualifications
