We are looking for an experienced DFT Verification Engineer to join our VLSI design team and drive the verification of Design-for-Test (DFT) architectures for complex SoC designs. In this role, you will be responsible for verifying scan logic, ATPG, MBIST, JTAG, and boundary scan implementations to ensure high fault coverage, robust testability, and production-ready silicon quality.

You will collaborate closely with Design, DFT, Physical Design, and Verification teams to validate DFT functionality, debug issues, and ensure successful verification closure across the chip development lifecycle.

Key Responsibilities

DFT Verification

• Validate DFT architectures and ensure correct implementation across complex SoC designs.
• Perform functional verification of DFT control logic and test modes.
• Review DFT specifications and ensure implementation aligns with design requirements.

Simulation & Debug

• Execute gate-level simulations (GLS) with SDF back-annotation to verify timing accuracy and DFT functionality.
• Debug DFT-related failures and perform root cause analysis in collaboration with cross-functional teams.
• Validate scan chain integrity, chain continuity, clock domain interactions, and test logic behavior.
• Ensure proper implementation of scan compression, X-masking, and clock domain constraints.

ATPG & Test Validation

• Support Automatic Test Pattern Generation (ATPG) validation and review fault coverage metrics.
• Verify test control logic and production test readiness.
• Review DFT verification results, identify coverage gaps, and recommend improvements.
• Participate in DFT sign-off activities to ensure high manufacturing test quality.

Automation & Methodology

• Develop and maintain automation scripts for DFT verification and regression flows.
• Improve verification efficiency using Perl, Python, or Shell scripting.
• Contribute to verification methodology enhancements and process improvements.
• Maintain documentation for verification plans, test cases, and sign-off reports.

Required Qualifications

• Bachelor's or Master's degree in Electronics, VLSI, Computer Engineering, or a related discipline.
• 5–8 years of hands-on experience in DFT Verification for complex ASIC/SoC designs.
• Strong understanding of:
• Scan Architecture
• Automatic Test Pattern Generation (ATPG)
• MBIST
• JTAG (IEEE 1149.1)
