Role Overview

We are looking for a Performance Modeling Architect who will develop the modeling and simulation frameworks used to guide architectural decisions across our platform. In thisrole, you will build models that capture the interaction between AI workloads, softwarestacks, and hardware architectures, enabling rigorous evaluation of system-leveltradeoffs. Your models will represent not only the SoC architecture and its components,but also key elements of the software stack and system behavior that ultimatelydetermine real-world performance. These frameworks will enable hardware–softwareco-design, allowing us to explore design alternatives and quantify their impact on performance, latency, scalability, and energy efficiency. Your work will directly influencethe architecture of next-generation AI compute platforms.

Responsibilities

• Develop system-level performance models for AI workloads and compute architectures.
• Build simulation frameworks that capture interactions between AI models, software runtimes, and hardware systems.
