Senior Performance Modeling Architect

Tenstorrent; Santa Clara (CA); On-site; USD 180,000 - 240,000; Full time

Job summary

Tenstorrent in Santa Clara, CA, is seeking a senior CPU architect for performance modeling and architectural exploration. You will bridge hardware and software perspectives, connect workload behavior to design decisions, and influence future CPU directions through rigorous modeling and analysis.

The role requires strong C++/Python skills, 8+ years in CPU architecture or related fields, and excellent communication to drive decisions across engineering teams.

Qualifications

• 8+ years of experience in CPU architecture, performance modeling, microarchitecture, or a closely related field.
• Strong analytical, problem-solving, and communication skills across architecture, hardware, and software teams.
• Experience using performance models, simulation, or quantitative analysis to guide real architectural decisions.
• Strong programming skills in C++, Python, or similar languages.

Responsibilities

• 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.
