DFT Engineer

Job Title

DFT Engineer

Role Summary

Responsible for implementing and validating Design-for-Test (DFT) methodologies for advanced ASIC/SoC products to improve testability and manufacturing quality. Works within the SoC engineering team and coordinates with RTL, Physical Design, and Verification groups.

Position is onsite/hybrid in Santa Clara, CA and focuses on pre-silicon DFT implementation and post-silicon test support.

Experience Level

Mid-level — experience listed as 3–12 years.

Responsibilities

Primary duties include designing, implementing, and validating DFT solutions and supporting silicon bring-up.

• Develop and implement DFT architectures for complex ASIC/SoC designs.
• Perform scan insertion, ATPG, MBIST, LBIST, and boundary-scan implementation.
• Run fault-coverage analysis and generate test patterns.
• Collaborate with RTL, Physical Design, and Verification teams on testability and integration.
• Debug DFT-related issues during simulation and silicon bring-up.
• Support compression techniques and low-power DFT methodologies.
• Validate test structures and support post-silicon activities and bring-up.
• Ensure required test coverage and quality metrics for tapeout.

Requirements

Must-have technical skills and experience required for the role; preferred items listed separately.

• Must-have: Strong understanding of DFT concepts and methodologies.
• Must-have: Hands-on experience with scan, ATPG, JTAG, MBIST, and compression flows.
• Must-have: Experience with DFT tools such as Tessent, SpyGlass DFT, Modus, or Tetramax.
• Must-have: Knowledge of Verilog/SystemVerilog and simulation/debug flows.
• Must-have: Familiarity with semiconductor design and test processes.
• Must-have: Scripting experience in Tcl, Perl, or Python.
• Nice-to-have: Experience with advanced process nodes and large SoC designs.
• Nice-to-have: Understanding of low-power DFT techniques.
• Nice-to-have: Prior silicon debug and bring-up experience.
• Nice-to-have: Strong analytical and communication skills.

Education Requirements
