About the role
Senior Circuit Characterization Engineer to define and drive post-silicon circuit setting and performance across NVIDIA’s GPU and SoC product families. Owns characterization of analog, digital, and mixed-signal circuits from first silicon through production, translating lab measurements into design improvements and product decisions. Not a test-and-report role; owns analysis from hypothesis through root cause and design impact.
Responsibilities
- Own Silicon Circuit bringup from first power on through production to optimize performance, power, yield, and quality for the world’s fastest products across process, voltage, and temperature corners.
- Drive circuit characterization for critical on-die circuits including SRAM, PLL/DLL, clock distribution, voltage regulators, I/O interfaces, and on-die sensors — correlating measured silicon behavior with pre-silicon simulations to close the design loop.
- Design experiments, execute test plans, and build models that isolate circuit-level bottlenecks.
- Lead multi-functional root-cause closure across architecture, design, validation, software/firmware, power and thermal, reliability, ATE, product management, manufacturing, and operations, own fixes through confirmation.
- Analyze production-silicon data across PVT corners and binning populations to quantify guardbands, yield trade-offs, and circuit optimization opportunities that feed directly into product definition and future architecture decisions.
- Establish reusable automation, data analysis pipelines, and visualization tools that improve characterization coverage, execution efficiency, and debug velocity across simultaneous product.
Qualifications
- BS or MS degree in Electrical Engineering, Computer Engineering, or equivalent experience.
- 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, PLL, 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, data analysis, and tool development; familiarity with C/C++ is a plus.
- Excellent problem-solving skills and a collaborative mindset — demonstrated ability to drive alignment across multi-site, cross-functional teams including offshore engineering organizations.
