About the role

DRAM Product Engineer responsible for developing advanced test methodologies and diagnostic techniques for next-generation memory systems, focusing on DRAM behavior across logical, architectural, and physical domains, and contributing to production-ready board/PCBA test solutions for high-volume AI accelerator boards.

Responsibilities

  • Develop and execute test strategies for DRAM devices and their interconnects, covering functional, timing, signal integrity, and reliability failure modes.
  • Diagnose complex DRAM issues across logical, architectural, and physical domains, including cell behavior, addressing, timing margins, and interface interactions.
  • Build, modify, and maintain simulation models to study DRAM behavior, interfaces, and test scenarios at multiple abstraction levels.
  • Use simulation tools to explore corner cases, stress conditions, and failure mechanisms prior to and alongside silicon testing.
  • Transform and correlate data between logical representations (addresses, transactions, algorithms) and physical implementations (cells, banks, rows/columns, wires, timing paths).
  • Analyze DRAM behavior with a deep understanding of circuit operation, including variability, noise, leakage, and process effects.
  • Apply statistical methods to large test datasets to identify trends, characterize distributions, isolate root causes, and support yield and reliability conclusions.
  • Use mathematical models to describe, predict, and explore DRAM test behavior, limitations, and tradeoffs.
  • Collaborate with design, architecture, and manufacturing teams to feed diagnostic insights back into design and test improvements.

Qualifications

  • BS or MS in Electronics and Electrical Engineering or related field.
  • Strong background in DRAM architecture, operation, and interfaces.
  • Solid understanding of DRAM failure modes, and associated test and characterisation methods.
  • Solid understanding of advanced CMOS electronic circuit behavior and its impact on memory operation.
  • Experience applying statistics to hardware test and characterization problems.
  • Strong mathematical skills applied to modeling, analysis, and problem solving in test development.
  • Ability to reason rigorously across abstraction levels, from physical circuits to logical test algorithms.
