Job Description

We are looking for an experienced Memory Subsystem Performance Architect to lead HBM performance modeling, analysis, and optimization of high-bandwidth memory subsystems for next-generation SoCs. This role drives architecture exploration from early concept through post-silicon, partnering closely with architecture, design, and software teams.

Responsibilities

• Develop and maintain C++ / SystemC performance models for HBM-based memory subsystems.
• Define and execute experiments to evaluate HBM architecture features, memory controller behavior, and system-level trade-offs.
• Identify performance bottlenecks across HBM, interconnect, caches, and compute, and propose architecture improvements.
• Collaborate with cross-functional teams (SoC, NoC, memory controller, power, software) to influence design decisions.
• Research and track industry trends and innovations in HBM, 3D-stacked memory, and advanced packaging.
• Support post-silicon performance characterization, correlation, and model refinement.

Minimum Qualifications

• 3+ years of experience in performance modeling, memory architecture, or system architecture.
• Strong C++ proficiency; experience with SystemC/TLM modeling.
• Solid understanding of memory hierarchies and DRAM systems.

Preferred Qualifications

• Hands-on experience with HBM2/HBM2E/HBM3 architectures.
• Experience with AI/ML, GPU, or HPC-class SoCs.
• Familiarity with post-silicon performance analysis and silicon correlation.
• Ability to translate performance data into clear architectural recommendations.
