Performance Architect, CPU Cluster

Job summary

Responsibilities

Compensation for all engineers at Tenstorrent ranges from $100k - $500k including base and variable compensation targets. Experience, skills, education, background and location all impact the actual offer made.

• How to architect, model, and optimize a multi-core CPU cluster from early performance exploration through implementation and silicon.
• How cache coherence, interconnects, memory hierarchy, and core architecture interact to determine overall system performance.
• How to model and reason about scaling across cores, including contention, bandwidth limits, latency, and workload behavior.
• How architectural decisions at the cluster level translate into real-world application performance.
• How Tenstorrent approaches scalable CPU and chiplet-based system architecture across compute, interconnect, and memory.

What they're looking for

• You have a strong foundation in CPU microarchitecture and performance, with an understanding of how cores, caches, interconnects, and memory systems interact.
• You enjoy using modeling, simulation, and workload analysis to understand cluster-level performance bottlenecks and scaling challenges.
• You’re comfortable moving between detailed microarchitecture and broader system-level questions around latency, bandwidth, quality of service, utilization, and scalability.
• You’re analytical and hands-on, with the ability to turn large amounts of performance data into clear architectural recommendations.
• You’re a strong communicator who enjoys working across architecture, RTL, compiler, software, and system teams.
