Hiring: Performance Architect, CPU Cluster Company: Tenstorrent Location: Santa Clara, CA Job Posted Time: 2026-09-17 04:54:08 Employment Type: Remote About the job Required Skills: •Analyze and optimize CPU cluster performance, including cache hierarchies, interconnects, coherence, and memory access behavior. •Build and use performance models and simulation environments such as Gem5 or equivalent to evaluate architectural concepts and identify performance opportunities. •Study real workloads to understand bottlenecks related to cache misses, coherence traffic, memory bandwidth, latency, contention, and core-to-core communication. •Lead architectural tradeoff studies across performance, scalability, bandwidth, latency, power, and implementation complexity. •Partner cross-functionally with CPU, cache, interconnect, memory, software, and system architects to translate performance analysis into concrete design decisions. •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. Qualifications: •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. Compensation: •$100,000 - $500,000 / year •Flexible work environment (work from home / hybrid options) Interested candidates, please apply directly through the job posting on company's career page or try via AI auto apply on this platform.
