Validation Engineer

Staff Validation Engineer 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.

• 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, 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.

• 8+ years of hands‑on experience in characterizing high‑speed interfaces, particularly memory‑related applications.

• Strong understanding of memory interface architecture and operation, preferably DDR
  5.

• 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.
