What is a PCIe engineer?

A PCIe Engineer is a professional who specializes in designing, developing, testing, and troubleshooting hardware and firmware related to PCI Express (PCIe) technology. PCIe is a high-speed serial computer expansion bus standard used to connect components like GPUs, SSDs, and network cards to a computer's motherboard. PCIe Engineers work on ensuring compatibility, optimizing performance, and resolving issues in systems that use PCIe interfaces, often collaborating with hardware, firmware, and software teams.
