What You Can Expect
We are looking for a Senior Staff DFT Engineer with hands-on experience in scan-based DFT implementation, including Scan Streaming Network (SSN) and IJTAG (IEEE 1687). This role focuses on end-to-end scan execution, from insertion and verification through DRC closure, coverage improvement, and final DFT signoff. The ideal candidate will own scan quality, coverage closure, and DFT signoff for complex SoC designs.

ESSENTIAL DUTIES AND RESPONSIBILITIES
Lead hands-on scan DFT implementation, including:Scan insertion and stitching
Scan Streaming Network (SSN) implementation
IJTAG (IEEE 1687) insertion and connectivity

Perform scan DFT verification, debug, and DFT DRC closure
Debug and resolve scan-related DRCs, connectivity issues, and control signal problems
Run, analyze, and debug SpyGlass DFT/RTL checks, partnering with design teams to resolve violations
Generate, simulate, and debug ATPG scan patterns
Analyze ATPG results and drive scan coverage improvement and closure
Develop and validate DFT-related timing constraints (scan, shift, capture, and test modes)
Create and maintain TCL scripts for scan insertion, ATPG setup, and coverage analysis
Optimize scan implementations for pattern efficiency and test quality
Support hierarchical scan integration at both block and SoC levels
Collaborate closely with RTL and Physical Design teams to resolve scan-related issues
Support pre-silicon DFT signoff and post-silicon pattern bring-up and debug
Assist with ATE pattern conversion and scan debug activities

What We're Looking For
Bachelor’s degree in Computer Science, Electrical Engineering or
related fields and 5-10 years of related professional experience OR Master’s degree and/or PhD in Computer Science, Electrical Engineering or
related fields with 3-5 years of experience.
8+ years of hands-on experience in DFT scan implementation

ATPG pattern generation and coverage analysis
IJTAG (IEEE 1687) and SSN implementation

Strong understanding of:Scan Streaming Network (SSN)
IEEE 1149.x, IEEE 1500, and IEEE 1687 standards

Proven ability to resolve scan DFT DRCs and drive coverage closure
Strong TCL scripting skills for automation and flow customization
Experience developing and validating scan and test-mode timing constraints
Full DFT lifecycle experience, from RTL/netlist through silicon debug
Strong debugging, ownership, and problem-solving skills
Excellent verbal and written communication skills

PREFERRED QUALIFICATIONS
Experience with scan compression and advanced scan architectures
Post-silicon experience, including:Pattern bring-up and debug
Silicon characterization and yield learning

Experience mentoring junior engineers or owning DFT scan signoff
