Drive end-to-end validation of high-speed Ethernet SerDes and PHY solutions across silicon, package, board, and system environments.
Develop characterization methodologies to assess performance, robustness, and design margins across operating conditions.
Support silicon bring-up activities and root-cause analysis of complex system-level issues.
Execute Advanced High-Speed Measurements
Eye-diagram measurements
BER and margin analysis
Channel loss and equalization analysis
End-to-end system interconnects
Work closely with design and architecture teams to translate lab findings into actionable design improvements.
Work with existing validation and data-analysis frameworks to improve test efficiency, repeatability, and coverage.
Contribute to automation solutions that streamline test execution, data collection, analysis, and reporting.
Work with Industry-Leading Test Platforms
Configure and operate advanced Keysight validation equipment, including:
Influence Next-Generation Products
Partner closely with SerDes, PHY, SI/PI, package, board, and system design teams.
Contribute to validation methodologies that will be used across future product generations.
Provide technical recommendations that directly influence product performance and customer success.
Drive Standards Compliance
Execute compliance and interoperability testing according to industry standards, including:
3dj Ethernet specifications
Ethernet compliance and interoperability test methodologies
Present findings to engineering stakeholders and leadership teams.
Drive issues to closure through data-driven analysis and collaboration.
