About the role

Senior SerDes Characterization Engineer role within Google's Platforms and AI & Infrastructure teams, focusing on transmitter/receiver characterization and high-speed interconnect testing across compute and networking platforms. Involves hands-on hardware characterization, test automation, collaboration with PHY/design teams, and reporting silicon health metrics. Based in Sunnyvale, CA.

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.

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).
