DFT Engineer

Job Title

DFT Engineer

Role Summary

Work on design-for-test (DFT) for a multi-core AI accelerator ASIC. The role focuses on scan insertion, ATPG, memory BIST, tool integration, and silicon bring-up to deliver a robust and scalable test solution for large SoCs.

The position sits on the SoC/test team and collaborates with physical design, test engineering, and product teams to enable production test and yield ramp.

Experience Level

Mid-level. No specific years of experience stated.

Responsibilities

Deliver and integrate DFT features across the SoC and support test execution.

• Contribute to DFT architecture for a multi-core AI accelerator SoC.
• Implement scan insertion, compression, and test logic.
• Generate and analyze ATPG patterns for structural faults.
• Support MBIST implementation and memory test strategies.
• Integrate DFT tools into the EDA flow and develop automation scripts.
• Coordinate with physical design to ensure clean scan chains and timing closure.
• Support silicon bring-up, debug, ATE pattern bring-up, and production test activities.

Requirements

Must-have technical skills and competencies for the role.

• Experience in DFT, digital design, or related ASIC development.
• Good understanding of scan, ATPG, memory BIST, and digital test concepts.
• Familiarity with mainstream EDA tools and flows.
• Scripting skills (Python, Tcl, or similar) to develop automation and analysis scripts.
• Ability to collaborate with cross-functional teams and work on complex system-level problems.
• Willingness to support silicon debug and production test activities.
• May require eligibility checks for export-controlled technologies; ability to comply with export control requirements.

Education Requirements

Degree in Electrical Engineering, Computer Engineering, or a similar field is specified.
