General Summary:

About the Team

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

Role Overview

Seeking an experienced DDR Validation Engineer for 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.

Key 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.

Required Qualifications

• 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
  • DDR controllers and PHYs
  • Memory training and calibration algorithms
  • Cache, coherency, and NoC architectures
  • Power management and low-power memory features
• Strong post-silicon debug experience.
• Proficiency in C/C++ and low-level software development.

Preferred 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.

Minimum Qualifications:

OR

Master's degree in Science, Engineering, or related field and 3+ years of ASIC design, verification, validation, integration, or related work experience.

OR

PhD in Science, Engineering, or related field and 2+ years of ASIC design, verification, validation, integration, or related work experience.
