Job Level

Tech Stack

About the role

  • Own SoC-level DFT implementation, including scan, MBIST, LBIST (as applicable), boundary scan (JTAG), and test access architectures for HBM base-die designs
  • Drive DFT architecture definition early in the design cycle, ensuring alignment with SoC integration, floor planning, timing, power, and physical design constraints
  • Implement and integrate DFT logic at the block, subsystem, and full-chip levels, working closely with RTL and integration teams
  • Own DFT flow execution and signoff, including lint, CDC, DFT rule checks, ATPG readiness, and coverage closure
  • Collaborate with physical design teams to ensure DFT solutions are optimized for placement, routing, timing closure, and DRC/LVS signoff
  • Work closely with verification, product engineering, test, probe, and manufacturing teams to ensure testability, diagnosability, and smooth silicon bring-up
  • Support pre-silicon debug of DFT-related issues and assist with post-silicon bring-up and yield/debug analysis
  • Partner with CAD and methodology teams to define, improve, and standardize DFT flows across HBM SoC programs

Requirements

  • Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, or related field
  • 7+ years of relevant experience in SoC design, DFT, or implementation for complex digital ASICs or SoCs
  • Experience with scan insertion, MBIST/LBIST architectures, JTAG/boundary scan, and ATPG concepts
  • Familiarity with full RTL-to-GDS SoC flows, including interaction between DFT, synthesis, STA, and physical design
  • Experience working with large, complex SoCs involving multiple IPs and subsystems
  • Proficiency with industry-standard EDA tools from Siemens, Synopsys, and/or Cadence for DFT and implementation
  • Familiarity with scripting languages (Python, Tcl, Perl, etc.) for flow automation
Benefits
  • Health insurance
  • 401(k) matching
  • Paid time off
  • Paid family leave
  • Medical, dental and vision plans
  • Income protection programs
  • Robust paid time-off program
