What You’ll Do
Technically Lead the architecture team with strong direction, shaping system‑architecture strategy and advancing key innovations
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 system-level architectural research (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 (<10%). What You Bring
Ph.D. in Computer Science, Electrical Engineering, or a related field preferred, with 15+ years of experience in system architecture for large-scale computing platforms, with a strong focus on AI workloads
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. - Innovative and creative, you proactively explore new ideas and adapt quickly to change. #LI-SF1
