Principal DFT Engineer

Job Title

Principal DFT Engineer

Role Summary

Implement and drive Design-for-Test (DFT) methodologies for complex ASIC and SoC products to ensure high-quality, high-volume production and manufacturing test readiness. The role partners with RTL, verification, physical design, and manufacturing teams through signoff, silicon bring-up, and yield improvement.

Experience Level

Senior - typically requires 8+ years of ASIC/SoC DFT experience.

Responsibilities

Primary responsibilities include architecture, implementation, validation, and production readiness of on-chip test features and flows.

• Develop and implement DFT architecture for ASIC and SoC designs.
• Perform scan insertion, scan chain planning, and scan compression implementation.
• Generate and validate ATPG patterns and analyze fault coverage results.
• Implement and verify MBIST and other on-chip test features.
• Collaborate with RTL, verification, and physical design teams for DFT integration.
• Support JTAG and boundary-scan implementation and debugging.
• Drive DFT signoff activities and manufacturing test readiness.
• Participate in silicon bring-up, failure analysis, and yield improvement efforts.

Requirements

Must-have technical skills and experience.

• 8+ years of ASIC/SoC DFT experience.
• Strong understanding of scan, ATPG, fault models, and test coverage methodologies.
• Hands-on experience with tools such as Synopsys TestMAX/TetraMAX, DFT Compiler, Siemens Tessent, Cadence Modus, or equivalent.
• Knowledge of Verilog/SystemVerilog and digital design fundamentals.
• Experience with Linux and scripting (Python, Tcl, Perl, or Shell).
• Strong debugging and problem-solving abilities.

Nice-to-have

• Experience with advanced-node semiconductor technologies.
• Hands-on experience with MBIST, compression architectures, and JTAG.
• Knowledge of timing closure, physical design impacts, and low-power design techniques.
• Experience supporting silicon validation and manufacturing production ramps.

Education Requirements

Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical field.
