Senior Performance Modeling Architect, CPU Fabric and LLC

Job description

We are looking for a highly skilled Performance Modeling Architect to lead the architectural definition and improvement of our next-generation CPU Cache Hierarchies and interconnects. This is an outstanding chance to create scalable solutions that connect two fast-paced domains: the high-reliability, low-latency needs of Automotive and the massive efficiency, high-density demands of Data Center systems. You will build the "source of truth" models that govern data movement across our silicon, ensuring our next-level caches (L3/System Cache) and coherent fabrics achieve ambitious performance goals. What you'll be doing: As a core member of the architecture team, your daily work will involve: Developing and maintaining high-fidelity, cycle-accurate performance models (C++/SystemC) for coherent interconnects and large-scale shared caches. Modeling and analyzing performance bottlenecks across varying scales, from small-cluster automotive SoCs to massive, multi-mesh data center architectures. Evaluating the performance impact of different coherency protocols (e.g., CHI, ACE, or proprietary) and snooping filters. Running and analyzing industry-standard benchmarks (SPEC, MLPerf, Automotive...
