Principal CPU Microarchitect - RISC-V & AI Compute

The role

The Principal CPU Microarchitect will drive the microarchitecture of custom RISC-V CPU cores. This role involves dissecting AI workloads to identify bottlenecks and designing custom instructions for the AI platform.

What you will do

• Dissect cutting-edge AI workloads to identify execution bottlenecks
• Translate insights into definitive CPU performance requirements
• Drive the microarchitecture of custom RISC-V CPU cores
• Balance Performance, Power, and Area (PPA) targets
• Design and implement custom instructions
• Partner across compiler, software, and hardware teams to co-design AI compute architecture

Required qualifications

• 10+ years of deep expertise in CPU performance modeling and microarchitecture design
• Deeply familiar with the computational and memory bottlenecks of modern AI workloads, particularly Large Language Models (LLMs)
• Driven to architect custom instruction set extensions and validate their performance gains against real-world workloads

Nice to have

• Familiarity with open-source RISC-V cores
• AI-based agentic workflow experience

Benefits

• Highly competitive compensation package

Before you apply

• Candidates will be assessed for the appropriate level during the interview process
• Offer of employment is contingent upon being eligible to access U.S. export-controlled technology
• Offer may be contingent upon citizenship/permanent residency status or ability to obtain prior license approval from the U.S. Commerce Department or applicable federal agency
