Job summary

Fractile is seeking a DRAM Product Engineer to design, implement, and support production-ready test solutions for a high-volume board integrating multiple AI accelerators and PCIe Gen6 interconnect. You will develop robust tests, diagnose DRAM issues, and collaborate across design, architecture, and manufacturing to drive memory test innovation.

This role focuses on understanding DRAM behavior across logical, architectural, and physical domains, using simulation, statistics, and modeling to

Qualifications

• BS or MS in Electronics and Electrical Engineering or related field.
• Strong background in DRAM architecture and interfaces.
• Solid understanding of CMOS circuit behavior and memory operation.

Responsibilities

• Develop and execute DRAM test strategies for DRAM devices and interconnects, covering functional, timing, signal integrity, and reliability fault modes.
• Diagnose 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.
