PSV DDR Validation Engineer

Position: PSV DDR Validation EngineerLocation: San JoseOnsite 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. Key skills - DDR, LPDDR4x, LPDDR5x, SOC, RISC-V, ARM, Python, Perl, C/C++), oscilloscopes, logic analyzers, BERTs, power analyzers, Lauterbach, JTAG, JEDEC LPDDR B.E/M. E in Electronics & Communication Engineering 10 to 15 years of experience 10+ years of SOC validation experienceAt 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.
