• Expertise in using high-bandwidth oscilloscopes such as Keysight UXR/URC series or equivalent platforms.
• Experience with active differential probes, probe amplifiers, interposers, test fixtures, and advanced high-speed measurement techniques.
• Strong knowledge of eye diagrams, jitter analysis, setup/hold timing, impedance, insertion loss, return loss, noise, and transmission line behavior.
• Ability to interpret schematics, PCB layouts, PHY specifications, and compliance requirements.
• Experience debugging hardware and PHY-level issues in pre-silicon or post-silicon environments.
• Proficiency in Python or similar scripting languages for test automation and data analysis.
• Strong analytical, troubleshooting, documentation, and communication skills.
• Experience with MIPI compliance methodologies, CTS procedures, and validation tools.
• Familiarity with protocol analyzers, pattern generators, BER testers, MIPI exercisers, and validation platforms such as Introspect, Unigraf, or Keysight solutions.
• Knowledge of signal integrity simulation tools such as ADS, HFSS, HyperLynx, or Sigrity.
• Exposure to post-silicon characterization, voltage and temperature corner testing, and margin analysis.
• Experience working in semiconductor, mobile, automotive, display, camera, or AR/VR product environments.
• Familiarity with Linux, Android, display pipelines, camera pipelines, or embedded systems environments.
