Senior Engineer Linux BSP and Driver Development (Ethernet/SerDes/PCIe)

Job Overview We are looking for a highly experienced Senior Engineer with a strong background in Linux BSP and driver development, specifically for Ethernet, SerDes, and PCIe IPs. The engineer will be responsible for board-level platform enablement, middleware stack integration, and driver development on embedded Linux platforms. Key Responsibilities Design, implement, and maintain Linux kernel drivers for Ethernet MAC, SerDes PHY, and PCIe interfaces. Develop and maintain BSP components such as bootloader configuration, device trees, and board-specific initialization. Integrate middleware stacks and protocol layers for high-speed communication interfaces (e.g., TCP/IP stack, PCIe enumeration). Enable and validate hardware IPs such as Gigabit Ethernet, multi-lane SerDes, and PCIe Root Complex/Endpoint. Debug low-level hardware/software issues using JTAG, logic analyzers, PCIe analyzers, and trace tools. Support bring-up of new boards with Ethernet/SerDes/PCIe subsystems. Ensure compliance with industry standards such as IEEE 802.3, PCIe Base Spec, and SERDES protocols. Collaborate with SoC, hardware, and system architects to define BSP requirements and integration points. Contribute to performance tuning, power management, and data path optimization for high-throughput interfaces.
