The ideal candidate will have hands-on experience with DDR5 buffer of silicon bring-up and validation, including high-speed analog and mixed-signal characterization.

This position requires an experienced technical lead with a strong background in post silicon validation across multiple product iterations. The ideal candidate will have hands-on experience of silicon bring-up and validation, including high-speed analog and mixed-signal characterization.. The candidate should be comfortable leading bench-level validation and characterization activities, driving debug efforts, developing test methodologies, and collaborating cross-functionally with design, system, and product engineering teams.

Component Bench Validation and Characterization

• Leverage best‐known test and measurement techniques—including de‐embedding, high‐impedance probing, and noise compensation—to address complex signal‐integrity challenges as memory data rates continue to scale.
• Support Design and Validation teams in the characterization of critical electrical and timing parameters for high‐speed memory devices.
• Collaborate closely with designers and cross‐functional partners to debug and optimize performance using exploratory, open‐ended test approaches that extend beyond strict specification‐driven measurements.

Data Analysis and Reporting

• Synthesize experimental results and systematically define subsequent validation and characterization experiments to fully isolate and understand complex issues.
• Generate clear, consistent, and well‐structured reports tailored to a range of technical and non‐technical audiences, ensuring actionable insights and alignment across teams.
• Develop and validate innovative applications of LLM/AI techniques to analyze large-scale validation datasets, generate effective visualizations, and reduce overall cycle time to final reporting.

Technical Communication

• Effectively document test methodologies, procedures, and assumptions to ensure results are reproducible, accurate, and scalable across validation efforts.
• Communicate complex technical concepts with an appropriate level of detail tailored to each stakeholder, from deep technical audiences to broader cross‐functional teams.
• Collaborate effectively with Validation Engineers across diverse geographic regions, languages, and technical backgrounds, fostering alignment and knowledge sharing within global teams.
• Bachelor's / Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 5+ years of hands-on experience in high-speed Analog and Mixed-signal signal devices.
• Strong understanding of signaling levels, termination architectures, and signal integrity tradeoffs in systems.
• Expertise in using typical high speed interface test equipment (BERT, Scope, Compliance S/W).
• Proficiency in scripting languages (e.g., Python) for test automation and analysis.
• Excellent analytical and problem-solving skills.
• Strong communication and interpersonal skills.
• Preferred Qualifications:
• Master's degree in Electrical Engineering
• Experience with advanced signal integrity measurements and applications for Design correlation.
• Strong understanding of memory interface architecture, interface protocols, standards and operation, preferably DDR5.
