PCIe FW Engineer

Responsibilities

• Design and implement firmware for PCIe initialization, link bring-up, and configuration space programming (BARs, capabilities, MSI/MSI-X)
• Develop MMIO-based control and status interfaces used by host software
• Work closely with DMA engines to enable high-bandwidth, low-latency data transfers
• Collaborate with hardware design teams on PCIe IP integration and bring-up
• Partner with validation teams on FPGA, emulation, and ASIC debug
• Profile and optimize PCIe throughput, latency, and interrupt efficiency
• Debug complex system-level issues spanning firmware, hardware, and host

Requirements

• Bachelor's or Master's degree in Computer Engineering or a related field
• 8+ years of hands-on experience in firmware or embedded systems development
• Strong experience with PCIe protocol fundamentals, including configuration space, BARs, MSI/MSI-X, and link states
• Proven experience in C/C++ firmware development on RTOS or bare-metal environments
• Solid understanding of MMIO, interrupts, DMA, cache coherency, and memory ordering
• Experience debugging low-level issues using JTAG, logic analyzers, or PCIe protocol analyzers
• Experience with storage or accelerator devices (NVMe-like protocols or custom command interfaces)

Preferred Qualifications

• Exposure to PCIe switch topologies and peer-to-peer (P2P) flows
• Experience with pre-silicon validation environments such as FPGA, emulation, or virtual platforms
• Familiarity with security, reset isolation, or secure boot interactions at the Front-End
