About The Position

We are seeking a hands-on PCIe Characterization Engineer to perform post-silicon electrical characterization and validation of high-speed SerDes physical-layer interfaces in a laboratory environment. The role focuses on conducting high-speed electrical measurements, analyzing signal integrity, and validating silicon performance. You will independently operate laboratory equipment, troubleshoot signal-level issues, interpret hardware schematics and PCB layouts, and automate characterization workflows using Python. The successful candidate will have direct experience with high-speed interface characterization and the practical skills needed to investigate electrical performance issues at the measurement and probe points.

Requirements

5+ years of experience in post-silicon characterization, HSIO validation, or memory electrical validation.
Experience working at a semiconductor, silicon, or systems company in areas such as SoC, GPU, networking, storage, or automotive compute.
Hands-on experience with high-speed SerDes PHY characterization.
Practical experience measuring eye diagrams, jitter, BER, and S-parameters.
Proficiency using high-speed oscilloscopes, BERT, and VNA/TDR equipment.
Experience reading and interpreting schematics and PCB layouts.
Strong laboratory debugging and electrical measurement skills.
Python scripting experience for test and measurement automation.
Strong analytical, troubleshooting, and problem-solving abilities.
Willingness to work on-site in Palo Alto, CA.
