Lead ASIC DFT (Design-for-Test) Engineer - Remote

Key Responsibilities

• Lead DFT architecture, implementation, verification, and sign-off for complex ASIC and SoC designs.
• Drive scan architecture, scan insertion, scan chain stitching, and scan compression workflows to achieve high coverage and robust testability.
• Own MBIST/LBIST integration, implementation, verification, and debug across design and silicon bring-up phases.
• Perform DFT debug, failure analysis, root-cause investigation, and fault coverage closure for complex silicon issues.
• Develop and validate DFT constraints, including DFT SDC, timing checks, and DFT-specific timing analysis.
• Collaborate with RTL design, verification, physical design, STA, and silicon validation teams to resolve integration and implementation issues.
• Support ATPG pattern generation, ATPG simulations, DRC analysis, test coverage analysis, and diagnosis/debug.
• Work on JTAG, boundary scan, iJTAG, SSN, and IP-level DFT integration.
• Review RTL, synthesis, LEC, and physical design impacts on DFT implementation and test quality.
• Act as a technical escalation point for advanced DFT and post-silicon debug issues.
• Mentor junior and mid-level DFT engineers and promote best practices in DFT methodology and automation.
• Develop scripts and automation using TCL, PERL, or Python to improve flow efficiency and debug productivity.
