Principal Engineer, RISCV Architect

Job Description

We are seeking a Principal/Sr. Principal RISC-V CPU Architect with 10 to 15 years of experience to lead the architecture, development, and assessment of next-generation RISC-V processor cores. The ideal candidate will have deep expertise in high-performance CPU micro-architecture and a comprehensive understanding of the RISC-V and thorough understanding of Micro controller and micro processor architecture.

Responsibilities:

• Core Architecture & Specification: Define and develop detailed micro-architecture specifications for RISC-V units, including branch predictors, rename logic, instruction scheduling, and vector execution.
• Design & Development: Lead the RTL development of CPU cores, ensuring alignment with power, performance, area (PPA), and timing goals.
• Assessment & Benchmarking: Evaluate and benchmark various RISC-V core implementations (in-order vs. out-of-order, superscalar) against target workloads and performance models.
• Virtualization & Security: Implement and optimize hardware-assisted virtualization features and architectural extensions for secure execution environments.
• Infrastructure & Fabric: Architect and integrate critical infrastructure elements, including Bus fabrics (e.g., CHI, AXI), clocking, reset logic, and power management subsystems.
• Full Design Flow Management: Oversee the complete design lifecycle from architectural exploration to physical design delivery, including functional and performance verification. 

Qualifications

• Education: Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, or a related technical field.
• Experience: 10–15 years in CPU/SoC architecture and RTL design.
• RISC-V Expertise: Thorough knowledge of the RISC-V ISA, including standard extensions (e.g., V-extension) and custom instruction sets.
• Micro-architecture Knowledge: Deep understanding of advanced techniques such as deep pipelines, cache hierarchies, MMUs, and SIMD units. Exposure to C/SystemC based models is preferred.
• Design Skills: Proficiency in Verilog/SystemVerilog and experience with simulators, waveform debuggers, and PPA optimization tools.
• Systems Integration: Familiarity with modern SoC fabric protocols and the integration of infrastructure elements like PLLs and power controllers.
• Mentorship: Proven ability to mentor junior architects and establish best practices across the design team.
