Senior Engineer - DFT

Job Title

Senior Engineer - DFT

Role Summary

Responsible for design-for-test (DFT) implementation for ultra-low-power SoCs operating at subthreshold/near-threshold voltages. The role focuses on scan insertion, MBIST, ATPG, and low-power DFT architecture and infrastructure, and works closely with RTL designers, physical design, power teams, and test engineers.

Experience Level

Senior-level - the posting specifies at least 10 years of experience in DFT implementation.

Responsibilities

Primary responsibilities include:

• Perform scan insertion, boundary scan, MBIST, and ATPG using standard EDA tools for ultra-low-power SoCs.
• Develop and implement low-power DFT architecture and infrastructure for complex SoCs.
• Generate structural test vectors and analyze/improve coverage, test time, and test cost.
• Run pre- and post-layout scan and MBIST simulations and develop test benches.
• Collaborate with designers on STA, physical, power, and logical issues related to DFT.
• Work with test engineering to bring up test vectors and production test programs on silicon.

Requirements

Must-have and preferred skills:

• Must-have: 10+ years of DFT implementation experience.
• Must-have: Proficiency with DFT structures including scan (Stuck-At, At-Speed, Path-Delay), scan compression, boundary scan, and MBIST.
• Must-have: Experience designing and implementing hierarchical DFT architecture for complex SoCs.
• Must-have: Experience with ATPG, MBIST test-bench development, and pre/post-layout simulation; strong understanding of test coverage and test time analysis.
• Must-have: RTL experience and extensive knowledge of timing concepts and constraint development.
• Must-have: Experience collaborating with test engineering for production test bring-up.
• Nice-to-have: Scripting experience (Tcl) and gate-level simulation (GLS).
• Personal attributes: motivated, self-driven, attention to detail, strong verbal and written English communication skills.

Education Requirements

BS or MS in Electrical/Electronic Engineering or Computer Engineering (ECE/EE) as stated in the posting.
