What you’ll do:

As a Senior ASIC Verification Engineer, you will be responsible for the verifying of inference chiplet & sub blocks that will run the smallest to largest AI models. Your primary duties and responsibilities include:

• Lead comprehensive verification planning and execution for fabric-level and full-chip designs, ensuring robust validation across all design hierarchies.
• Collaborate cross-functionally with architecture, firmware, and design teams to develop detailed test plans that validate implementation against specifications and requirements.
• Design and implement advanced testbenches featuring constrained random stimulus generation, intelligent checkers, comprehensive scoreboards, and targeted assertions to ensure design correctness and coverage.
• Architect and execute verification strategies encompassing test planning, coverage analysis, automated regression management, and data-driven insights to maximize verification efficiency and quality.
• Drive verification excellence through established methodologies including structured code reviews, agile sprint planning, and systematic feature deployment processes.
• Innovate verification approaches by researching and implementing next-generation methodologies, automated flows, and emerging technologies including AI-driven verification tools.

What You Bring To The Table:

• Educational Foundation: Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related technical discipline.
• Proven Experience: 5-10 years of hands-on verification experience spanning test plan development, simulation environment creation, test implementation, and complex debugging across diverse IP blocks, SoCs, and system-level designs.
• Specialized Expertise: Demonstrated proficiency in fabric-level and chip-level verification methodologies and best practices.
• Technical Mastery: Advanced skills in SystemVerilog/Verilog, UVM methodology, and C/C++ programming, including embedded code development and validation for RISC-based processors.
• Verification Leadership: Established track record in creating scalable verification flows, implementing coverage-driven verification strategies, and developing assertion-based verification frameworks.
