Responsibilities
Take lead responsibility for validating DDR memory subsystems (LPDDR4x, LPDDR5x) on multiple SoC platforms
Define comprehensive test plans and execute tests covering memory training procedures, performance benchmarks, stress scenarios, timing margin analysis, and overall reliability
Collaborate with design and firmware teams to develop, integrate, and debug firmware essential for memory training. Write necessary firmware components (like bootloaders, memory drivers, test hooks) to enable testing
Integrate and debug firmware for memory initialization and training, specifically on systems using RISC-V or ARM processors
Work closely with software and hardware teams to ensure firmware and hardware components interact correctly. Coordinate with board and Signal/Power Integrity (SI/PI) teams for related evaluations
Utilize standard lab equipment (oscilloscopes, logic analyzers, BERTs, power analyzers) for test execution, data collection, and troubleshooting memory-related issues. Perform root cause analysis for failures
Develop scripts (Python, Perl, C/C++) to automate test procedures and validation workflows
Qualification
Required
BSEE/BSCE or equivalent experience
10+ years of SOC validation experience
At least 5 years of experience in post-silicon Memory subsystem validation, with a specific focus on LPDDR4x or LPDDR5 memory subsystems
Strong C/C++ programming skills, particularly for low-level code (like hardware abstraction layers) used in system bring-up
Proven experience integrating and debugging firmware in memory validation or general SoC environments
Deep understanding of DRAM operations, memory controller architecture, standard memory training algorithms, and JEDEC LPDDR standards (including timing parameters)
Experience with silicon bring-up processes and associated tools like Lauterbach debuggers, JTAG interfaces, and trace analyzers
Familiarity with embedded operating systems and the typical boot sequences
System-level memory performance tuning and characterization
