AI CPU Design Engineer

Job Title

AI CPU Design Engineer

Role Summary

Design engineer responsible for microarchitecture and RTL development of AI-enabled RISC-V CPU cores in the MIPS S8200 family. The role owns feature definition, performance/power/area trade-offs, and collaborates with verification and physical design teams to deliver a production CPU IP.

Experience Level

Mid-level — preference for candidates with 6–10 years of relevant CPU/RTL design experience.

Responsibilities

Primary responsibilities include microarchitecture, RTL design, and support for verification and physical implementation.

• Drive microarchitecture and design of critical CPU core blocks.
• Design RISC-V vector CPU core and custom vector extensions.
• Design AI-enabled matrix engine to augment the vector datapath.
• Conduct high-level architectural exploration and translate results into detailed microarchitectural specifications.
• Develop, assess, and refine RTL to meet power, performance, area, and timing targets.
• Support functional verification and contribute to verification strategy.
• Work with CPU modeling and physical design teams on timing, area, reliability, testability, and power trade-offs.
• Comply with Environmental, Health, Safety & Security requirements in all activities.

Requirements

Must-have technical skills and experience required to perform the role.

• Hands-on experience with vector processors or GPUs.
• Experience in datapath design for vector and matrix processing (floating-point and integer datatypes).
• Strong knowledge of microprocessor architecture, including one or more of: instruction fetch/decode and branch prediction; instruction scheduling, register renaming, ROB; out-of-order execution; integer and floating-point execution; load/store execution; prefetch; vector datapath; cache and memory subsystems.
• Proficiency in RTL languages: SystemVerilog, Verilog and/or VHDL.
• Experience with simulation and waveform debugging tools.
• Understanding of logic design principles and the timing and power implications of design decisions.

Nice-to-have:

• Experience designing RISC-V, ARM, and/or MIPS CPUs.
• Experience with hardware multithreading, virtualization, and SIMD designs.
• Experience with vector- and matrix-enabled CPUs, preferably RISC-V.
• Knowledge of low-power microarchitecture techniques and high-performance trade-offs.
• Scripting experience (Perl, Python) and SoC-level CPU integration knowledge.
• Familiarity with safety and security microarchitecture concepts.

Education Requirements

Bachelor's degree required. The posting specifies 6–10 years of work experience. Fields of study were not specified in the source.
