Senior Principal Verification Engineer

Job Title

Senior Principal Verification Engineer

Role Summary

Lead verification of CPU cores and related subsystems (coherency and cache controllers) on the CPU verification team. Define verification strategy, develop UVM-based testbenches and test cases, and work with architects and designers to ensure functional correctness and performance.

Experience Level

Senior-level — 15+ years of experience in design verification, preferably with CPU or SoC verification.

Responsibilities

Key responsibilities include:

• Perform functional verification of CPU cores and related subsystems, including coherency and cache controllers.
• Interpret microarchitectural specifications and translate them into verification plans and strategies.
• Develop UVM-based testbenches and write directed and constrained-random tests in SystemVerilog, C, and assembly.
• Analyze coverage reports and drive closure of functional and coverage gaps.
• Automate regression and verification flows using scripting (Python, Perl, Shell).
• Collaborate with architects, designers, and senior engineers to resolve design issues and improve verification quality.
• Follow Environmental, Health, Safety & Security (EHS&S) requirements in day-to-day activities.

Requirements

Must-have skills and experience:

• 15+ years of hands-on design verification experience, preferably in CPU or SoC verification.
• Proven experience with SystemVerilog and UVM and constrained-random verification methodologies.
• Familiarity with CPU architectures such as RISC-V, ARM, or MIPS.
• Basic understanding of cache and coherency concepts.
• Strong scripting skills (Python, Perl, or Shell) to automate flows and regressions.

Nice-to-have:

• Exposure to RISC-V architecture.
• Knowledge of interconnect protocols (AXI, ACE, CHI).
• Experience with FPGA prototyping or emulation platforms.

Education Requirements

Bachelor's degree in Electronics, Electrical, or Computer Engineering.
