Validation engineer Jobs in Phoenix, AZ

Job Description

This position requires an experienced technical lead with a strong background in silicon validation across multiple product iterations. The ideal candidate will have hands-on experience with DDR5 buffer, including high-speed analog and mixed-signal characterization. A solid understanding of memory interfaces used in server and enterprise applications is highly preferred. 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.

Qualifications

• Bachelor's / Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 8+ years of hands-on experience in characterizing high-speed interfaces, particularly memory-related applications.
• Strong understanding of memory interface architecture and operation, preferably DDR5.
• In-depth knowledge of memory interface protocols and standards (e.g., JEDEC specifications).
• Strong understanding of memory-interface signaling levels, termination architectures, and signal integrity tradeoffs in high-speed DDR 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.
