Senior CPU Architect

Job Title

Senior CPU Architect

Role Summary

Senior CPU modeling architect responsible for defining and implementing modeling architecture for RISC-V based embedded CPUs used in NVIDIA GPU and Tegra SoC. The role focuses on SystemC, QEMU, and performance models and requires collaboration with system software, system architects, and CPU architects to deliver accurate, high-quality virtual platforms.

Experience Level

Senior — typically 3+ years with a master's degree or 5+ years with a bachelor's degree in relevant experience; similar senior-level experience accepted.

Responsibilities

Accountabilities include defining model architecture, building virtual platforms, and improving model performance and power efficiency.

• Define architecture for next-generation SystemC and QEMU models for RISC-V CPUs.
• Develop and maintain performance models and virtual platforms.
• Optimize model performance and power efficiency.
• Validate models, diagnose and fix functional and performance issues, and deliver production-quality CPU models for GPU and Tegra SoC integration.
• Collaborate with CPU architects, system architects, and system software teams to capture requirements and ensure models meet use cases.

Requirements

Must-have technical skills and relevant experience. See Education Requirements for degree information.

• 3+ years (MS) or 5+ years (BS) experience in CPU, DSP, vector processor design, or related areas.
• Strong programming skills in C/C++ and SystemC.
• Practical experience with CPU model frameworks (e.g., GEM5, QEMU, Spike).
• Experience building and validating virtual platforms and performance models for embedded CPUs.
• Proven ability to diagnose and resolve model functional and performance issues.

Education Requirements

BS or MS in Electrical Engineering, Computer Engineering, Computer Science, Electronics Engineering, or a related technical field; PhD candidates also welcome. Equivalent practical experience is explicitly accepted.
