Job Description:

• Testplan Ownership: Review architectural and micro-architectural specifications to define, architect, and author comprehensive, feature-driven verification plans (testplans).
• Environment Development: Design, build, and maintain scalable, reusable, and robust constrained-random verification environments from scratch using SystemVerilog (SV) and the UVM methodology.
• Verification Strategy: Define effective verification strategies at the block, sub-system, and/or SoC level, incorporating both simulation and formal techniques where applicable.
• Debugging & Triage: Efficiently debug complex test failures, identify RTL or testbench defects, and collaborate closely with Design and Architecture teams for rapid resolution.
• Coverage & Sign-off: Define, implement, and analyze functional (covergroups, coverpoints, crosses) and code coverage. Drive the verification closure process to achieve 100% coverage targets.
• Mentorship: Provide technical guidance and mentorship to junior verification engineers, participating in code and testplan reviews to maintain high engineering standards.

• 5+ years of dedicated experience in ASIC/SoC Design Verification with bachelors or master's in ECE, EEE, Embedded Systems, VLSI

• Core Fundamentals: Strong understanding of digital logic design, computer architecture, FIFO, pipelines, memory controllers, and clock/reset domains.
• Languages: Advanced proficiency in SystemVerilog (SV) and Object-Oriented Programming (OOP) concepts.
• Methodology: Extensive, hands-on experience with UVM (Universal Verification Methodology) including writing sequences, drivers, monitors, scoreboards, and predictors.
• Coverage Closure: Proven track record of writing complex functional coverage models and successfully closing both code and functional coverage.
• Debugging: Mastery of industry-standard debugging tools (e.g., Verdi, DVE) and a methodical approach to root-causing complex RTL/TB bugs.
• Protocols: Familiarity with standard on-chip protocols (e.g., AXI, AHB, APB, PCIe, NVMe, USB, or Ethernet) depending on the specific team focus.
• Scripting: Experience with scripting languages (Python, Perl, or Tcl) and Shell scripting to automate verification workflows.

• Excellent analytical and problem-solving skills.
• Strong communication skills with the ability to collaborate effectively across cross-functional teams (Design, Architecture, and Validation).
• Self-motivated with a strong sense of ownership and attention to detail.
