Job summary

Unconventional is building a new foundation for AI hardware, seeking a Senior DFT Engineer to advance testability in advanced nodes. You will lead DFT architectures, implement scalable test strategies, and drive sign-off across complex designs.

You will work at the intersection of architecture and silicon, delivering reliable testability for novel computing platforms and collaborating with foundries and design teams to optimize yield and performance.

Qualifications

• BS or MS in Electrical/Computer Engineering or related field.
• 10+ years of industry experience in digital DFT and test architecture with tapeouts on modern process nodes (7nm, 5nm, or newer preferred).
• Deep expertise in scan compression, MBIST generation, fault modeling (stuck-at, transition, path delay), and ATPG.
• Understanding of physical design challenges in advanced nodes and their impact on test reliability.
• Expertise in Static Timing Analysis (STA) and timing closure for complex designs in shift and capture test modes.
• Mastery of standard EDA CAD tool suites for DFT implementation and vector generation; strong scripting in Tcl, Python, or Perl.

Responsibilities

• Lead DFT architecture and testability implementations for complex SoCs.
• Drive hierarchical DFT methodologies for large-scale designs and integrate test patterns.
• Collaborate with foundry interfaces to analyze defect densities and improve test yield.
• Advance 2.5D/3D multi-stacked die DFT coverage across die interfaces.
• Develop analog mixed-signal DFT strategies and ensure testability of custom blocks.
• Optimize test time, coverage, and yield in collaboration with architects and PPA goals.
• Own ATPG, ATPG vector validation, and STA timing closure for test modes.
• Contribute to design flow automation and engage partners for AI tooling.
