In short

Qualcomm seeks an experienced DDR Validation Engineer for end-to-end validation of LPDDR5X and LPDDR6 memory subsystems on AI Accelerator and Flagship mobile platforms. The role involves memory bring-up, performance validation, system stress, debug, and production readiness across pre- and post-silicon phases.

Responsibilities

Define and execute DDR validation strategy across emulation, FPGA, and silicon platforms.
Drive LPDDR5X/LPDDR6 bring-up, training validation, frequency scaling, low-power state validation, and feature enablement.
Develop and execute validation plans covering memory functionality, performance, reliability, power, and corner-case scenarios.
Lead debug of DDR controller, PHY, firmware, SI/PI, timing, and system-level issues.
Validate interactions between DDR, CPU, GPU, NPU, cache hierarchy, NoC, and system software.
Drive bandwidth, latency, QoS, memory pressure, and AI workload characterization.
Develop scalable automation, regression infrastructure, and debug analytics frameworks.
Partner with Architecture, Design, Firmware, SI/PI, Package, and DRAM vendors to root-cause and resolve issues.

Requirements

BS/MS/PhD in EE, CE, CS, or related field.
5+ years of experience in DDR/memory subsystem validation or silicon bring-up.
Strong understanding of LPDDR4/5/5X/6 architectures.
Strong understanding of DDR controllers and PHYs.
Strong understanding of memory training and calibration algorithms.
Strong understanding of cache, coherency, and NoC architectures.
Strong understanding of power management and low-power memory features.
Strong post-silicon debug experience.
Proficiency in C/C++ and low-level software development.
Bachelor's degree in Science, Engineering, or related field and 4+ years of ASIC design, verification, validation, integration, or related work experience.
Master's degree in Science, Engineering, or related field and 3+ years of ASIC design, verification, validation, integration, or related work experience.
PhD in Science, Engineering, or related field and 2+ years of ASIC design, verification, validation, integration, or related work experience.

Desired Qualifications

Mobile SoC, AI compute, automotive, or server platform validation experience.
Familiarity with SI/PI analysis, memory performance tuning, and thermal characterization.
Experience driving first-silicon memory bring-up and volume production qualification.
