Job Overview:
We are looking for a highly experienced Senior Engineer with a solid 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.
