Principal SoC DFT Engineer

The Principal DFT Engineer will work on cutting-edge ASIC implementation for the Network Infrastructure Optical Network group

You will be working on DFT architecture and implementation across logic BIST, MBIST, BISR, Boundary Scan, and JTAG. This is a highly execution-driven role requiring end-to-end ownership of DFT insertion, verification, DRC closure, and test coverage closure from RTL/netlist through post-silicon debug. As a senior member of the DFT team, you will work closely with the architecture, IP design, Physical Design and product engineers to achieve first pass silicon success.

Perform hands-on DFT implementation and verification, including:

• Logic BIST and scan compression
• MBIST and BISR
• Boundary Scan (IEEE 1149.x) insertion
• JTAG insertion and connectivity
• High-speed analog/mixed signal IP integration
• Execute DFT verification, debug, and DFT DRC closure
• Identify, debug, and resolve DFT rule violations at both block and top levels
• Run, analyze, and debug DFT/RTL checks, working with design teams to close violations
• Generate, simulate, and debug MBIST and logic ATPG patterns
• Analyze test results and drive test coverage improvement and closure
• Develop and validate DFT timing constraints for scan, BIST, and test modes
• Create and maintain TCL scripts to automate DFT insertion, verification, and analysis flows
• Support hierarchical DFT implementation and resolve integration issues
• Collaborate with RTL and Physical Design teams to address DFT-related design issues
• Support pre-silicon DFT signoff and assist with post-silicon pattern bring-up and debug
• Assist with ATE pattern conversion and debug as needed

Experience with gate-level simulations and debugging with industry simulator tools

You Have:

• Bachelor’s degree in computer science, Electrical Engineering or related fields and 8 years

  • ATPG pattern generation and coverage analysis
• Proven ability to resolve DFT DRCs, connectivity issues, and testability problems
• Strong TCL scripting skills for DFT automation and flow execution
• Experience developing and validating scan and test-mode timing constraints
• End-to-end DFT lifecycle experience, from RTL/netlist through silicon debug
• Strong debugging skills, attention to detail, and sense of ownership
• Excellent verbal and written communication skills
