DFT Engineer

DFT Engineer – Associate III – Semiconductor Product Validation

We are seeking a DFT Engineer with strong understanding of scan design, ATPG, fault models (stuck‑at, transition, path delay), and test compression techniques.

• Define and implement DFT architecture including scan, MBIST, LBIST, and boundary scan for ASIC/SoC designs
• Develop and integrate scan chains, compression techniques, and test points to achieve high fault coverage
• Perform ATPG pattern generation, simulation, and debug to meet coverage & quality goals
• Work closely with design, physical design, and verification teams to ensure DFT readiness across all design stages
• Execute DFT checks such as DRC, LVS, and timing closure in coordination with backend teams
• Debug silicon bring‑up issues related to test failures and yield improvement
• Analyze test coverage reports and implement strategies to improve fault coverage and reduce test time
• Support manufacturing test, including tester bring‑up, pattern validation, and failure analysis
• Develop and maintain DFT documentation, test plans, and sign‑off reports

• Bachelor's or Master's degree in Electronics/Electrical Engineering or related field
• 5+ years of experience in DFT for ASIC/SoC development
• Hands‑on experience with industry‑standard DFT and ATPG tools such as Synopsys DFT Compiler, TetraMAX, or Cadence Modus
• Experience in MBIST/LBIST insertion and validation
• Familiarity with JTAG/IEEE 1149.x standards and boundary scan implementation
• Good knowledge of Verilog/System Verilog and scripting languages like Tcl or Python
• Understanding of physical design impact on DFT (timing, congestion, power)
• Strong debugging and problem‑solving skills

• Experience with low‑power DFT techniques and multi‑voltage domain designs
• Exposure to silicon bring‑up and yield analysis
• Knowledge of tester platforms like Advantest or Teradyne
• Experience working in advanced nodes (7nm/5nm or below)
• Strong communication and collaboration skills
• Ability to work in cross‑functional global teams
• Self‑driven with a proactive approach to problem‑solving
