General Summary

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
