We’re dedicated to empowering people to be their true selves. Together, we’re building a better tomorrow for our employees, customers, partners, and communities. Staff Engineer , Architecture & Performance Research Engineer for Data Center and Agentic AI CPU   What You’ll Do Architecture Research Lab is focused on researching next-generation CPU (RISC-V) microarchitecture and performance for emerging computing workloads. We explore new architectural ideas, evaluate their performance potential, and rapidly turn promising concepts into working designs that can be validated on real silicon. Our research is driven by emerging opportunities in data center and agentic AI workloads, where we investigate how CPU architecture can evolve to meet new performance and efficiency requirements. We also explore CPU-memory co-design from the CPU perspective, in alignment with the broader shift toward memory-centric architectures. A distinctive aspect of our team is the way we approach architecture research. We develop and apply AI-driven methodologies to accelerate architectural exploration, broaden the design space we can investigate, and quickly iterate from ideas to implementation and silicon validation. Rather than simply following established design flows, we continuously seek new ways to explore, evaluate, and realize CPU architectures. The role offers an opportunity to work across the full spectrum of architecture research—from workload and performance analysis, microarchitectural innovation, and architectural modeling to implementation and silicon validation—while helping shape new methodologies for how future CPUs are designed.   Location: Daily onsite presence at our San Jose office in alignment with our Flexible Work policy Job ID: 43004 As a Staff CPU Architecture & Performance Engineer, you will shape the architecture and performance direction of next-generation CPU architectures. You will identify opportunities across emerging workloads, develop and refine performance models, evaluate system-level architectural trade-offs, and drive new microarchitectural concepts from research to implementation. You will work closely with RTL design teams to translate architectural concepts into implementable designs, guide key technical decisions, and validate their impact from modeling through silicon. The role offers broad ownership across architectural domains, with the opportunity to define new research directions, influence CPU architecture strategy, and drive ideas that can deliver meaningful performance gains in real hardware.  Propose new architecture ideas and take ownership of one or more microarchitectural domains, including front-end, mid-end, and back-end Use AI-driven design methodologies to rapidly implement architectural ideas and validate them on real silicon Build, extend, and validate performance models and architectural simulators Perform CPI/IPC analysis and identify root causes of performance bottlenecks Evaluate microarchitectural features and optimizations using trace-driven, analytical, and cycle-accurate models Characterize workloads and benchmarks, including SPEC, server, client, AI/ML, agentic AI, and internal traces Translate performance analysis and modeling results into architectural direction and design decisions Drive research leading to patents and technical publications What You Bring   Master’s degree in Computer Engineering, Computer Science, or a related field with 8+ years of relevant experience, or PhD with 5+ years of relevant experience 4+ years of experience in CPU microarchitecture or performance engineering Experience designing RISC-V, ARM, x86 CPU cores, or GPU/NPU vector unit Strong understanding of out-of-order execution, branch prediction, pipelines, speculation, and cache/memory systems Hands-on experience with architectural simulators such as gem5 Proficiency in C/C++ and Python Experience analyzing large-scale performance data and traces Preferred Qualifications Experience with AI-driven or agentic design workflows, including high-level design languages and AI-assisted RTL generation, or a strong interest in and ability to quickly learn such methods Understanding of agentic AI workload execution patterns Domain-specific experience in one or more of the following areas: Front-end: Branch prediction and decoupled fetch, particularly for compiler- or interpreter-driven workloads Mid-end: RVV/SIMD, matrix/tensor engine design, and out-of-order vector execution Back-end: LSU/MSHR design and prefetcher design for irregular access patterns Experience with PPA trade-off analysis Experience leading and mentoring junior engineers Experience with CPU tapeout or silicon validation Experience with patents or technical publications You’re inclusive, adapting your style to the situation and diverse global norms of our people. You approach challenges with curiosity and resilience, seeking data to help build understanding. You’re collaborative, building relationships, humbly offering support and openly welcoming approaches.
