The Architecture Research Lab (ARL) focuses on addressing fundamental system‑level bottlenecks in modern AI, particularly in memory capacity/bandwidth and system‑scale communication. By leveraging Samsung’s world‑class memory technologies, ARL explores and defines next‑generation AI system architectures that deliver step‑function improvements in performance, efficiency, and scalability.

• Conduct system‑level architectural research for next‑generation AI systems, spanning compute, memory, and interconnect/network subsystems.
• Develop and maintain analytical and simulation‑based system modeling frameworks to evaluate AI workloads and identify performance, scalability, and efficiency bottlenecks at rack‑ and system‑scale.
• Analyze representative and emerging AI workloads (e.g., LLMs, DLRMs, and future AI models) to derive architecture requirements and trade‑offs across compute, memory, networking, and power.
• Drive architecture‑level design decisions through quantitative modeling, design‑space exploration, and performance/power projections.
• Perform comparative studies of alternative system architectures, reporting performance and performance‑per‑watt metrics to guide strategic technology choices.
• Collaborate closely with cross‑functional teams in hardware architecture, memory, interconnect, and system engineering to align modeling insights with implementation realities.
• Communicate architectural insights and recommendations through clear technical presentations and documentation.

Occasional domestic and international travel.

• Proven hands‑on experience developing analytical and event‑driven simulation models for system‑level performance evaluation.
• Deep understanding of AI system hardware architectures, including compute, memory hierarchies, and high‑performance interconnects.
• Strong knowledge of modern and emerging AI workloads, including LLMs, DLRMs, and large‑scale training and inference systems.
• Demonstrated ability to translate workload characteristics and modeling results into actionable architectural design decisions.
• Proficiency in Python, C++, and PyTorch for modeling, analysis, and experimentation.
• Excellent written, verbal, and presentation communication skills, with the ability to influence technical direction across teams.
• A collaborative mindset, intellectual curiosity, and resilience in tackling complex, open‑ended system‑level challenges.
• You’re inclusive, adapting your style to the situation and diverse global norms of our people.
• You approach challenges with curiosity and resilience, seeking data to help build.
• Understanding. You’re collaborative, building relationships, humbly offering support and openly welcoming approaches.
