Senior Circuit Characterization Engineer

Job Title

Senior Circuit Characterization Engineer

Role Summary

As a Senior Circuit Characterization Engineer in NVIDIA's Silicon Co-Design Group (SCG) in Shanghai, you will own post-silicon circuit bring-up and characterization from first power-on through production for GPU and SoC products. You will translate lab measurements into root-cause analysis, simulation correlation, guardband recommendations, and design changes that improve performance, power, yield, and product quality.

Experience Level

Senior - typically requires 8+ years of relevant hands-on experience in post-silicon characterization, silicon bring-up, or circuit validation.

Responsibilities

Key responsibilities include leading characterization campaigns, analysis, and cross-functional closure from hypothesis to confirmed fixes.

• Own silicon circuit bring-up from first power-on through production to optimize performance, power, yield, and quality across process, voltage, and temperature corners.
• Characterize critical on-die circuits (SRAM, PLL/DLL, clock distribution, voltage regulators, I/O interfaces, on-die sensors) and correlate measured behavior with pre-silicon simulations.
• Design experiments, execute test plans, and build models that isolate circuit-level bottlenecks.
• Lead multi-functional root-cause resolution across architecture, design, validation, firmware, reliability, ATE, manufacturing, and operations; own fixes through confirmation.
• Analyze production-silicon data across PVT corners and binning populations to quantify guardbands, yield trade-offs, and optimization opportunities.
• Develop reusable automation, data-analysis pipelines, and visualization tools to improve characterization coverage and debug velocity.

Requirements

Must-have technical skills and experience; followed by preferred qualifications.

• 8+ years of hands-on experience in post-silicon circuit characterization, silicon bring-up, or circuit validation on complex SoC or GPU products.
• Deep understanding of analog, digital, and mixed-signal circuit behavior, including SRAM, PLLs, clock networks, voltage regulators, I/O circuits, and on-die sensors.
• Hands-on lab proficiency with oscilloscopes, spectrum analyzers, DAQ systems, source meters, high-speed probing, and tester-to-system correlation workflows.
• Strong background in power-supply and substrate-noise analysis: chip- and board-level dI/dt characterization, PDN impedance, droop measurement, and mitigation techniques.
• Proficiency in Python and scripting for automation and data analysis; familiarity with C/C++ is a plus.
• Excellent problem-solving skills and proven ability to drive alignment across multi-site, cross-functional teams.

Nice-to-have:

• Experience characterizing circuits at advanced process nodes on large-scale GPU or datacenter SoC products.
• Background in on-die noise measurement methodology (NMEAS), worst-case noise test development, noise watermarking, or Bayesian/ML-driven characterization optimization.
• Familiarity with product binning, frequency-voltage optimization, guardband analysis, and statistical techniques for large characterization datasets.
• Experience with pre-silicon circuit simulation tools (SPICE, timing analysis) and silicon-to-simulation correlation workflows.
• Experience applying AI/ML methods to analysis, debug, or continuous improvement workflows.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related technical field - or equivalent practical experience.
