Job Description

This position is for a hands-on validation and characterization engineer with solid experience across multiple product iterations. The ideal candidate has strong expertise in DDR5/high-speed memory interfaces and is comfortable working at the bench as well as collaborating closely with design and global validation teams. Experience with buffer chips and server/enterprise memory applications is highly desirable

Component Bench Characterization

• Perform detailed bench characterization of high-speed memory devices using best-known measurement techniques and test methodologies.
• Apply de-embedding, high-impedance probing, noise mitigation, and signal integrity best practices to resolve complex measurement challenges at increasing data rates.
• Support Design and Validation teams in the characterization of key electrical and performance parameters.
• Work collaboratively with Designers and other cross functional teams to debug and optimize performance using open-ended tests not solely driven by specifications.

Validation Infrastructure Development

• Develop new test infrastructure to support effective characterization and validation of high-speed memory interfaces.
• Design and implement custom test procedures, scripts, and automation to improve test coverage and efficiency.
• Identify cycle-time and cost improvements, including automation, to improve validation efficiency.

Data Analysis and Reporting

• Synthesize results and identify the next set of relevant experiments to fully understand issues.
• Generate consistent, well-written, and easily understandable reports and presentations tailored to different audiences.
• Develop and validate creative uses of LLM/AI techniques to analyze large validation datasets, generate effective visualizations, and reduce cycle time to final reports.

Technical Communication

• Effectively document test methodologies and procedures to ensure reproducible and accurate results.
• Explain complex topics at an appropriate level of detail for each stakeholder.
• Work effectively with Validation Engineers across diverse regions, languages, and technical backgrounds.

Qualifications

Required Qualifications:

• • Bachelor's / Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
  • 6+ 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).
  • Expertise in using typical high speed interface test equipment (BERT, Scope, Compliance S/W).
  • Proficiency in scripting languages (e.g., Python, Perl) for test automation and analysis.
  • Excellent analytical and problem-solving skills.
  • Strong communication and interpersonal skills.

Preferred Qualifications:

• • Master's degree in Electrical Engineering or a related field.
  • Experience with advanced signal integrity measurements and applications for Design correlation.
  • Experience with modern software tools for data visualization, analysis, and reporting; in particular dynamic interactive tools – including LLMs
