• Integrate and customize vendor SAI implementations for SONiC and other NOS, and resolve SDK/SAI interaction issues.
• Bring up high-speed links and transceivers (112G/224G PAM4, QSFP-DD/OSFP, CMIS), debugging with PRBS, FEC/BER, and eye diagnostics.

BSP & Platform

• Lead BSP development for x86 and ARM switch platforms: ONIE, bootloader (GRUB/U-Boot), Linux kernel configuration, and device tree/ACPI.
• Design and maintain Linux kernel and platform drivers for CPLD/FPGA, I2C/SMBus, LPC, PCIe, and fan/PSU/thermal management (SONiC platform API / pmon).

Technical Ownership

• Define platform software design for new programs and lead design and code reviews.
• Drive root-cause analysis of cross-domain issues together with hardware engineers and Broadcom/Marvell FAEs.
• Support EVT/DVT/PVT builds and manufacturing diagnostics, and represent the team in customer technical reviews.

• Hands-on experience with at least one Ethernet switch ASIC SDK (Broadcom or Marvell).
• Expert C programming skills; working proficiency in C++ and Python.
• Strong Linux kernel and driver development skills: interrupts, DMA, PCIe, I2C, and concurrency.
• Delivered platform bring-up of at least one switch or server product from EVT to mass production.
• Solid knowledge of L2/L3 forwarding (MAC learning, VLAN, IP routing, ARP, LAG, ECMP).
• Good English communication skills for working directly with vendors and customers.

Preferred Qualifications

• Experience with Broadcom Tomahawk / Trident / Jericho or Marvell Prestera / Teralynx silicon.
• SONiC platform porting experience (device/platform packages, pmon, syncd) or ONIE.
• PAM4 SerDes tuning and CMIS transceiver management at 400G/800G.
• Data center / AI fabric features: RoCEv2, PFC/ECN, buffer tuning.
