Senior DFT Engineer

About the Role

onsemi is seeking a DFT Engineer to support the design and implementation of Design‑for‑Test (DFT) features for complex ASIC/SoC products across automotive and industrial applications. This role focuses on scan, ATPG, MBIST, and boundary scan, with close collaboration across design, PD, and test teams.

Key Responsibilities

• Develop and integrate DFT architectures including Scan, ATPG, MBIST, and JTAG
• Implement and debug DFT logic to ensure high fault coverage and test quality
• Generate and analyze ATPG patterns using industry‑standard tools
• Support at‑speed and transition fault testing
• Collaborate with RTL, Physical Design, STA, and Test Engineering teams
• Address timing, CDC, and low‑power DFT considerations
• Support test coverage analysis, DFT signoff, and silicon bring‑up

• #LI-RT1

Required Qualifications

• 3–5 years of experience in ASIC / SoC DFT
• Strong understanding of: 
  • Scan, ATPG, MBIST, JTAG
  • Fault models: stuck‑at, transition, at‑speed
• Hands‑on experience with DFT tools such as: 
  • Synopsys DFT Compiler / TestKompress
  • Siemens Tessent or equivalent
• Familiarity with timing, CDC, and low‑power DFT flows
• BS/MS (B.Tech/M.Tech) in Electrical Engineering or related field

 #LI-RT1

Preferred Qualifications

• Experience with advanced nodes and large SoCs
• Exposure to physical‑aware DFT and test‑related ECOs
• Working knowledge of UPF and low‑power test strategies
• #LI-RT1
