• Perform high-speed SERDES and Ethernet device measurements using oscilloscopes, BERT, protocol analyzers, and related equipment
• Document quality engineering processes and methodologies for scalability
• Collaborate with design, validation, hardware, and systems teams on reliability improvements
• Support new product development with enhanced failure analysis capabilities

What they're looking for

• High-speed SERDES and signal integrity knowledge
• PCIe and Ethernet protocol understanding
• Lab instrumentation operation (oscilloscopes, BERT, TDR, spectrum analyzers, VNA)
• Hardware debugging and failure analysis
• Root-cause analysis methodology
• Technical documentation and communication
• Cross-functional collaboration
• Problem-solving and analytical thinking
