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.

Good to Have: 

• Experience with SR-IOV, PCIe Hotplug, and PCIe Switches. 
• Familiarity with Linux networking features like DPDK, Netfilter, VLAN, and TSN. 
• Exposure to secure boot and secure firmware loading for Ethernet/PCIe devices. 
• Understanding of PHY/Link layer testing procedures for SerDes. 
• Experience with embedded Linux distributions in networking SoCs or server-class edge devices. 

Soft Skills: 

• Strong analytical and debugging skills for complex SoC platforms. 
• Good communication and documentation skills. 
• Ability to lead technical discussions and mentor junior engineers.
