Linux PCIe Driver Developer

Responsibilities

• Architect and implement high-performance user-space driver libraries for Linux to support Next Gen Computational PCIe Flash Controllers.
• Design and implement mechanisms for PCIe device discovery, enumeration, and topology management in complex multi-card environments.
• Develop a custom, NVMe-like command and control protocol in user space, including command queues and orchestration.
• Integrate user-space and kernel-space interactions using ioctl, mmap, and eventfd mechanisms.
• Design memory and dataflow management strategies, including DMA buffer lifecycle management and zero-copy data paths.
• Enable concurrent multi-process access to devices while ensuring isolation and scalability.
• Collaborate with runtime, kernel driver, firmware, and hardware teams to deliver cohesive end-to-end solutions.

Requirements

• 8+ years of experience in system software or runtime development.
• Proven expertise in building user-space drivers or high-performance system software interacting with kernel interfaces (ioctl, mmap, eventfd).
• Deep understanding of PCIe and NVMe-like queue models, including submission/completion queues and asynchronous execution.
• Mastery of C/C++ and a strong understanding of memory management, concurrency, and virtual memory.
• Experience designing scalable APIs and abstractions for complex hardware/software systems.
• Bachelor's or Master's degree in Computer Science, Electrical Engineering, or a related field.
