Principal SerDes Validation Engineer
$150,680–$225,700 year
On-site · Santa Clara, California, United States
Job Summary
Complete responsibility for PCIe/Ethernet PHY Validation in post-silicon environment. Define, document, execute and report the overall PHY validation/test plan for Marvell storage devices. Lab-based silicon bring-up and unit test execution focused on PCIe Physical and PCS layer hardware and firmware functionality, while also extending to the protocol layer of the PCIe stack. Perform high speed signal validation and analysis using various test equipment to measure Eye diagram/Jitter/BER. Analyze and debug issues on Phy protocol of storage interface ( SATA, SAS, PCIe, Ethernet ). Troubleshoot failing tests with diagnostics, software tools, hardware analyzers, oscilloscopes, meters, logic/protocol analyzers. Lead collaborative technical discussions to drive resolution on technical issues. Work with cross-functional teams and external vendors to debug post-silicon and/or customer issues related to PCIe PHY. Work closely with customers to address design issue and debug failure cases. Note: We welcome candidates at various experience levels for this role and offers will align with the level.
