Validation Engineer Post Silicon- Validation & Characterization in Tempe

Company Overview

Renesas is a global semiconductor company providing hardware and software solutions for a range of cutting‑edge technologies including self‑driving cars, robots, automated factory equipment, and smart home applications. We are a key supplier to the world’s leading manufacturers of electronics, and our solutions drive products developed by major innovators around the world.

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 with DDR5 silicon bring‑up and validation, including high‑speed analog and mixed‑signal characterization, and will 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.

• 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.
• 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.
• 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, technical backgrounds, fostering alignment and knowledge sharing within global teams.

• Bachelor's or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 8+ years of hands‑on experience with high‑speed analog and mixed‑signal devices.
• Strong understanding of signaling levels, termination architectures, and signal‑integrity trade‑offs in systems.
• Expertise in using typical high‑speed interface test equipment (BERT, oscilloscope, compliance software).
• Proficiency in scripting (e.g., Python) for test automation and analysis.
• Excellent analytical and problem‑solving skills.
• Strong communication and interpersonal skills.
• Master’s degree in Electrical Engineering (preferred).
• Experience with advanced signal‑integrity measurements and applications for design correlation.
• Strong understanding of memory interface architecture, protocols, standards, and operation, preferably DDR
