Staff Engineer CPU IP Design Engineer

Job Title

Staff Engineer CPU IP Design Engineer

Role Summary

Lead RTL development of an AI-enabled RISC-V CPU core and associated matrix/vector engines. The role owns microarchitecture, RTL design, and collaborates with verification, modeling, and physical design teams to meet performance, power, area, and timing targets.

Experience Level

Senior — staff-level engineering role. See Education Requirements for the employer's specified experience guidelines.

Responsibilities

Primary responsibilities include microarchitecture and RTL development, performance optimization, and cross-team integration.

• Define and drive micro-architecture for critical CPU blocks.
• Design RISC-V vector CPU core and custom ISA extensions.
• Design and integrate AI-enabled matrix engine that augments the vector datapath.
• Perform microarchitecture exploration and produce detailed specifications from early models to final RTL.
• Develop and refine RTL to meet power, performance, area, and timing goals.
• Support functional verification and contribute to verification strategy.
• Assist verification of RTL performance and work with modeling teams on high-performance strategies.
• Collaborate with physical design teams on timing, area, reliability, testability, and power integration.
• Follow and support Environmental, Health, Safety & Security requirements.

Requirements

Must-have technical skills and practical experience; preferred items listed separately.

• Hands-on knowledge of CPU pipeline stages for in-order or out-of-order high-performance cores.
• Deep microprocessor architecture experience, including one or more of: instruction fetch/decode and branch prediction; instruction scheduling and register renaming; ROB and out-of-order execution; integer/FPU pipelines; load/store execution; prefetch; vector datapaths; cache and memory subsystems.
• Understanding of cache coherence and memory consistency models.
• Proficiency in SystemVerilog, Verilog and/or VHDL and experience with simulators and waveform debugging tools.
• Solid grasp of digital logic design, timing, and power trade-offs.

Education Requirements

Employer requests a Master's degree with approximately 4–7 years of relevant experience, or a PhD with approximately 2–5 years of relevant experience. No other degree fields or equivalents were specified.
