Job Description: Principal Digital DFT Engineer

Role Summary

The Principal Digital DFT Engineer is responsible for architecting, implementing, and verifying advanced DFT solutions for complex digital ASICs and SoCs. This position emphasizes direct technical execution, deep problem-solving, and ownership of DFT flows for robust testability and manufacturing yield.

Key Responsibilities

• Own and drive all aspects of DFT architecture, definition, and implementation for digital chips, including scan insertion, ATPG, boundary scan, MBIST, logic BIST, JTAG and test compression techniques.
• Hands-on execution with EDA tools for scan synthesis, test pattern generation, fault simulation, and DFT rule checks.
• Create and validate test plans targeting high coverage for stuck-at, transition, and critical path faults.
• Integrate DFT with RTL and physical design teams; resolve complex trade-offs impacting fault coverage, PPA, or manufacturability.
• Optimize test modes, design for manufacturability, and debug silicon failures from bring-up through production ramp.
• Develop and implement low-overhead test structures and warranty schemes for new and legacy IP.
• Directly debug, analyze, and resolve DFT-related issues in simulation, emulation, and in the lab using standard test equipment.
• Deliver documented DFT architectures, test strategies, implementation scripts (TCL/Python/Perl), and design guidelines for engineering teams.
• Collaborate with ATE test engineers to implement production test solutions, reduce test costs, and improve coverage.
• Mentor engineers in DFT methodology, best practices, tool usage, and industry standards.

Required Qualifications

• Bachelor's or Master's degree in Electrical/Electronics/VLSI Engineering or equivalent.
• 10+ years' proven hands-on experience in DFT for digital ASIC/SoC development, with multiple tapeouts for large designs.
• Expert skills in DFT flows: scan, ATPG, MBIST, BIST, JTAG, boundary scan, fault simulation.
• Strong command of EDA tools: Synopsys DFT Compiler, Tessent, Cadence Modus, or equivalent.
• Scripting abilities (TCL, Python, Perl) for DFT automation and reporting.
• Solid knowledge of RTL design, synthesis, timing, and SoC architecture constraints.
• Demonstrated ability to debug complex DFT and test-mode issues at lab and production level.
• Ability to create technical documentation, guides, and mentor junior engineers.

Nice-to-Have Skills

• Experience with DFT for advanced nodes (≤ 7nm), 2.5D/3D packaging, or high-speed IP.
• Production ATE pattern development and test data evaluation.
• Knowledge of safety (ISO or security-oriented DFT requirements.
• DFT for memory BIST (SRAM/DRAM), and custom macro testing.
