## About the Role

* A CPU architect, performance architect, or performance modeling engineer with experience influencing CPU architecture or microarchitecture decisions.
 * You have a strong understanding of modern processor architecture and enjoy digging into why a CPU performs the way it does.
 * You are comfortable combining hardware architecture, software, data, and analytical modeling to solve complex performance problems.
 * You can move between high-level architectural questions and detailed analysis of CPU pipelines, memory systems, workloads, and bottlenecks.
 * A strong collaborator and technical communicator who can turn complex modeling results into clear recommendations and drive decisions across engineering teams.

What We Need

 * 8+ years of experience in CPU architecture, performance modeling, microarchitecture, performance analysis, or a closely related field.
 * Strong understanding of CPU architecture and microarchitecture, including areas such as pipelines, execution, scheduling, branch prediction, caches, memory hierarchy, and data movement.
 * Demonstrated experience using performance models, simulation, or quantitative analysis to guide real architectural decisions.
 * Strong programming skills in C++, Python, or similar languages, with experience developing or extending modeling and analysis tools.
 * Strong analytical, problem-solving, and communication skills, with the ability to work effectively across architecture, hardware, and software teams.

## Description

* Gain deeper exposure to the full CPU architecture and development process, from early architectural exploration through implementation and silicon.
 * Expand your ability to connect performance models and workload behavior to real hardware design decisions.
 * Work across CPU architecture, software, compilers, and system teams to understand performance from multiple perspectives.
 * Develop new approaches to modeling, workload analysis, and architectural exploration as processor designs become increasingly complex.
 * Help shape the performance characteristics and architectural direction of future generations of Tenstorrent CPUs.
