Qualcomm•San Diego, CA

3d•$145,600 - $218,400

About The Position

Qualcomm’s System Validation & Emulation (SVE) team is part of the central SoC validation organization responsible for ensuring end-to-end silicon quality across pre- and post-silicon phases. This team focuses on content quality and system-level validation enablement, offering deep exposure to Qualcomm SoCs through bare-metal validation content, scalable automation frameworks, and complex system debugs. Engineers in this role work across HW and SW boundaries to develop, validate, and scale system-level test content, ensuring high-quality silicon validation across a wide range of SoC domains. Excellent Opportunity to work on cutting-edge SoCs across multiple product segments, including: Premium mobile and flagship platforms, Data center, AI Accelerator platform. Seeking an experienced DDR Validation Lead to drive end-to-end validation of next-generation LPDDR5X and LPDDR6 memory subsystems on AI Accelerator and Flagship mobile platforms. This role will lead memory bring-up, performance validation, system stress, debug, and production readiness from pre-silicon through post-silicon phases.

Requirements
