You Are:

UST is searching for a DFT Engineer with strong understanding of scan design, ATPG, fault models (stuck-at, transition, path delay), and test compression techniques.

The opportunity:

• 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 and 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.

This position description identifies the responsibilities and tasks typically associated with the performance of the position. Other relevant essential functions may be required.

What you need:

• 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, Tetra

MAX, 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

• Desired

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
