Senior Engineer, Architecture & Performance Research Engineer Data Centerand Agentic AI CPU

Please Note:

To provide the best candidate experience amidst our high application volumes, each candidate is limited to 10 applications across all open jobs within a 6-month period.

Our technology solutions power the tools you use every day--including smartphones, electric vehicles, hyperscale data centers, IoT devices, and so much more. Here, you'll have an opportunity to be part of a global leader whose innovative designs are pushing the boundaries of what's possible and powering the future.

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.

Daily onsite presence at our San Jose office in alignment with our Flexible Work policy

As a Senior CPU Architecture & Performance Engineer, you will drive both microarchitectural research and performance modeling for next‑generation CPU architectures. You will analyze emerging workloads, develop and refine performance models, identify architectural opportunities, and turn quantitative insights into new microarchitectural concepts. You will work closely with RTL design teams to evaluate, refine, and implement promising ideas, taking them from architectural modeling through RTL and silicon validation.

The role offers significant ownership in shaping new CPU architectures and determining which ideas can deliver meaningful performance gains in real hardware.
