About the role

Senior Mixed Signal Design Validation Engineer focusing on validation of high-speed memory interfaces (LPDDR, GDDR, HBM) for NVIDIA GPUs and AI platforms. Lead bring-up, characterization, system-level validation, debugging, and collaboration across multiple teams to ensure memory interface quality and performance.

Responsibilities

  • Lead and drive the creation of validation test plan and test scripts for DDR I/O associated with LPDDR, GDDR, and HBM memory interfaces, ensuring all necessary required analog and digital circuits are covered.
  • Conduct thorough characterization of analog, digital, and mixed-signal circuit blocks under varying conditions (process, voltage, temperature) and correlate results with simulations.
  • Drive system-level validation for memory interfaces, ensuring high-speed performance and quality metrics meet the demanding standards required by our GPU and AI systems.
  • Investigation validating Memory I/O circuit to understand circuit weakness paving ways circuit improvement, architecture enhancement in future products.
  • Lead debugging efforts and design creative solutions to resolve unexpected bugs.
  • Validate silicon performance, quality, and margins for refinement of memory interface designs.
  • Develop and implement test scripts to optimize DDR I/O circuit, sub-circuits and overall system performance.
  • Work closely with multi-functional teams, including Mixed signal design, PISI team, hardware, firmware, and Memory qualification engineer, to resolve issues and improve the performance for memory interfaces.
  • Develop and implement tools and scripts to enhance electrical characterization and chip bring-up processes.
  • Mentor and train new engineers on validation practices, encouraging a culture of excellence and continuous improvement.

Qualifications

  • A BS degree or equivalent experience with 8 years experience or higher in Electrical Engineering, Computer Engineering, or a related field.
  • Solid experience in silicon bring-up and debugging, particularly for high-speed memory interfaces
  • Strong understanding of Memory system and specifications.
  • In-depth technical knowledge of mixed-signal circuits, analog, and digital systems, with a specific focus on high-speed memory technologies.
  • Strong knowledge of signal integrity and power integrity.
  • Experience with lab instrumentation, such as oscilloscopes, logic analyzers, spectrum analyzer, TDR, phase noise analyzer, signal generators and BER tester.
  • Strong scripting skills in Python, C, or similar languages, with experience in Git and JMP for version control and data analysis.
  • Ability to work in a fast-paced, dynamic environment that involves multiple-chip bring-ups and system validations.
  • Tight-knit collaboration are required to work effectively with multi-functional teams.
  • Strong problem-solving skills, with a proactive and forward-thinking approach.
