What You Bring
- Master’s degree in Computer Engineering, Computer Science, or a related field with 18+ years of relevant experience, or PhD with 15+ years of relevant experience
- 5+ years of experience in CPU microarchitecture, architecture research, or performance engineering, with a demonstrated track record of driving architectural direction
- Extensive experience designing and evaluating high-performance CPU architectures, including RISC-V, ARM, or x86 cores; experience with GPU/NPU vector or accelerator architectures is also relevant
- Proven ability to use quantitative performance analysis and modeling to identify architectural opportunities, evaluate system-level trade-offs, and influence major microarchitectural decisions
- Deep expertise in at least one major microarchitectural domain, with the ability to drive architectural direction and technical decisions in that area:
- Front-end: Branch prediction, fetch/decode, instruction delivery, and decoupled front-end architectures
- Mid-end: Out-of-order execution, scheduling, RVV/SIMD, vector execution, or matrix/tensor acceleration
- Back-end: Load/store units, MSHRs, cache and memory systems, prefetching, or irregular memory access optimization
- Hands-on experience building, extending, and applying architectural simulators and performance models, such as gem5, to guide architecture decisions
- Strong programming skills in C/C++ and Python, with experience developing tools and automation for performance analysis and architectural exploration
- Demonstrated ability to take architectural concepts from research and modeling through RTL implementation and silicon validation
Preferred Qualifications
- Experience defining or influencing CPU architecture for emerging workloads, particularly AI/ML, agentic AI, or data center applications
- Experience with AI-driven architecture and design methodologies, including AI-assisted architecture exploration, high-level design, or RTL generation
- Strong perspective on memory-centric architectures and CPU-memory co-design, with experience translating memory-system characteristics into CPU architectural opportunities
- Experience driving system-level PPA trade-offs across performance, power, area, and implementation complexity
- Experience taking architectural concepts through RTL implementation, tape-out, and silicon validation
- Experience leading cross-functional architecture initiatives and influencing technical direction across multiple engineering teams
- Proven ability to mentor and develop senior technical engineers and shape architecture research across multiple domains
- Track record of impactful architectural innovation through patents, publications, or deployed products
- 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.
- Innovative and creative, you proactively explore new ideas and adapt quickly to change
