• Proficiency in Verilog/SystemVerilog and simulation tools (VCS, Xcelium, Questa).
• Exceptional debugging and problem-solving skills with ability to work independently.
• Team organization, leading and driving skills.

Responsibilities

• Architect, set up, and debug functional verification environments across multiple design blocks and subsystem levels.
• Serve as the protocol expert, providing clarity on expected behaviors of AMBA and high-speed interfaces (DDR/LPDDR).
• Debug mismatches between RTL, DV models, and specifications, ensuring functional correctness and compliance.
• Develop and maintain UVM-based testbenches, scripts, and flows to automate verification compile/run cycles.
• Triage and root-cause simulation failures, track bugs, and drive closure with cross-functional teams.
• Optimize simulation runtime, capacity, and compile turnaround for large-scale designs.
• Maintain detailed documentation of methodologies, flows, and known issues.
