Senior SerDes Characterization Architect – Platforms

Google; Sunnyvale (CA); On-site; USD 159,000 - 230,000; Full time

Job summary

Google is seeking a hardware-focused engineer in Sunnyvale to design and validate TX/SerDes across cutting-edge compute and networking platforms.

You will lead characterization, develop automated test pipelines, and collaborate with PHY/signal integrity teams to optimize transmitter performance, drive settings, and test coverage. The role emphasizes rapid iteration in a lab environment and partner/vendor coordination.

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Physics, a related field, or equivalent practical experience.
• 4 years of experience in high-speed electrical characterization, SerDes validation, or physical layer testing.
• Experience with high-speed TX characterization and advanced test instrumentation (e.g., DCA, real-time scopes, spectrum analyzers).

Responsibilities

• Own transmitter (TX) and receiver characterization and compliance testing for Serializer/Deserializer (SerDes) interfaces across next generation compute and networking platforms.
• Execute detailed TX physical layer metrics analysis, including Signal-to-Noise-and-Distortion Ratio, jitter decomposition, eye linearity, transition time, and pulse response measurements. Ensure test compliance against applicable IEEE 802.3, OIF-CEI, and proprietary high speed interconnect specifications.
• Define and deploy automated test suites utilizing high performance real time and equivalent time (sampling/DCA) oscilloscopes, phase noise analyzers, and spectrum analyzers.
• Partner with Physical Layer (PHY) design and signal integrity engineers to evaluate TX FIR filter presets, correlate silicon behavior against pre-silicon models, and optimize transmitter drive settings.
• Develop robust data processing pipelines and visualization dashboards to report silicon health and parametric distributions.
