What You Will Do Perform MIPI D-PHY and C-PHY electrical characterization and compliance testing. Validate MIPI DSI/DSI-2 and CSI-2 transmitter and receiver interfaces. Configure and operate high-bandwidth oscilloscopes, including Keysight UXR/URC series. Set up MIPI electrical compliance test applications and automated validation environments. Execute high-speed and low-power mode measurements including: Eye diagram analysis Jitter and timing measurements Rise/fall time analysis Voltage level measurements Lane-to-lane skew analysis HS/LP transition timing verification Clock-to-data timing measurements Common-mode and differential voltage analysis Perform C-PHY three-wire signal measurements and eye-diagram validation. Debug electrical failures related to signal integrity, impedance, termination, reflections, noise, crosstalk, and power integrity. Analyze compliance test failures and determine root causes across PHY, PCB, package, firmware, test setup, and device configuration. Develop validation plans, characterization procedures, automation scripts, and test reports. Collaborate with silicon, hardware, firmware, display, camera, and system validation teams to drive issue resolution. Support board bring-up, silicon characterization, qualification testing, and production-related debug activities. Maintain detailed documentation of test setups, results, defect analysis, and corrective actions. What You Will Bring Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, or a related field. 5-10 years of experience in electrical validation, high-speed interface validation, signal integrity, or post-silicon characterization. Hands-on experience with MIPI D-PHY and/or C-PHY electrical validation and compliance testing. Strong understanding of MIPI DSI/DSI-2, CSI-2, display, and camera interface technologies. 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.
