Location: Palo Alto, CA (On-site) Job Type: Contract Job Overview We are seeking an experienced PCIe Characterization Engineer to perform post-silicon electrical characterization and validation of high-speed SerDes PHYs. This role involves hands-on laboratory testing, electrical measurement, signal integrity analysis, and debugging of high-speed interfaces across PCIe, Ethernet, UFS, and LPDDR5 technologies. The ideal candidate has a strong background in post-silicon characterization or high-speed I/O (HSIO) validation, with practical experience using advanced lab equipment and developing Python scripts for test automation. Key Responsibilities • Perform post-silicon electrical characterization of high-speed SerDes PHYs and memory interfaces. • Conduct eye diagram, jitter, bit error rate (BER), and S-parameter measurements. • Operate high-speed oscilloscopes, bit error rate testers (BERT), vector network analyzers (VNA), and TDR equipment. • Analyze schematics and PCB layouts to identify signal integrity issues and support electrical debugging. • Perform hands-on troubleshooting and debug at the probe point to isolate and resolve hardware-level issues. • Develop and maintain Python scripts for laboratory test automation, data collection, and analysis. • Analyze characterization results, document findings, and collaborate with cross-functional engineering teams to improve interface performance. • Support validation activities for high-speed interfaces, including PCIe, Ethernet, UFS, and LPDDR5. Required Qualifications • 5+ years of experience in post-silicon characterization, HSIO validation, SerDes validation, or memory electrical validation. • Hands-on experience characterizing high-speed electrical interfaces in a semiconductor or systems engineering environment. • Proficiency with high-speed oscilloscopes, BERT, VNA, and/or TDR measurement equipment. • Practical experience measuring and analyzing eye diagrams, jitter, BER, and S-parameters. • Ability to read and interpret schematics and PCB layouts for hardware-level debugging. • Experience with Python scripting for laboratory automation and test data analysis. • Strong troubleshooting, analytical, and problem-solving skills. • Ability to work on-site in Palo Alto, California. Preferred Qualifications • Experience with PCIe, Ethernet, UFS, LPDDR5, or other high-speed SerDes and memory interfaces. • Background working with SoCs, GPUs, networking hardware, storage systems, or automotive computing platforms. • Experience with signal integrity analysis and post-silicon hardware validation. • Previous experience in semiconductor, silicon design, or systems companies. Ideal Candidate Profile Candidates with titles such as PCIe Characterization Engineer, Signal Integrity Engineer, HSIO Validation Engineer, Post-Silicon Validation Engineer, or SerDes Validation Engineer are encouraged to apply. Candidates currently based in the San Francisco Bay Area are strongly preferred due to the on-site nature of the position.
