DFT Engineer

Position : DFT Engineer
Location : Austin,TX / San Jose,CA 
Duration : Long-term contract

The Role

We are seeking highly skilled and motivated Senior/Staff DFT (Design for Test) Engineers with a strong focus on high-performance digital design to take end-to-end ownership of robust, testable silicon, from early test strategy definition to verified DFT implementation, pattern generation, and silicon bring-up. You will join a multidisciplinary group creating next-generation accelerators where digital, optical, and mixed-signal domains intersect. The ideal candidate will have extensive experience in the DFT of large-scale, high-volume ASICs and a passion for developing reliable, high-coverage test architectures that drive breakthrough AI hardware

Responsibilities

• Architect, own, and implement the comprehensive Design-for-Test (DFT) strategy for complex high-throughput digital pipelines in advanced CMOS nodes, ensuring high test coverage and efficient test execution.
• Lead the integration and verification of all DFT features, including Scan, JTAG, Boundary Scan, and Memory BIST, ensuring adherence to industrial standards and sign-off criteria.
• Partner with the test engineering team to develop, validate, and optimize ATE-compatible test patterns (stuck-at, transition, bridging, etc.) to achieve aggressive fault coverage and maximise manufacturing yield.
• Drive RTL development (SystemVerilog / Verilog / VHDL) with a focus on DFT architecture, including synthesis constraints for test structures, and collaborate on formal and constrained-random verification of DFT logic.
• Analyse and minimise the DFT impact on power, performance, and area (PPA), implementing innovative techniques for efficient test access and execution.
• Collaborate with mixed-signal and software teams to define and optimise DFT interfaces, test modes, and firmware abstractions for test control and diagnosis.
• Mentor junior engineers, lead DFT design reviews, and champion best-practice methodologies for testability and debug across the ASIC development lifecycle.

Skills & Experience

• 7+ years of handson DFT architecture, implementation, and verification for highperformance ASICs or SoCs, including ownership of at least one product with comprehensive DFT coverage.
• Proven success implementing and verifying advanced DFT features (e.g., Scan/ATPG, Boundary Scan, Memory BIST/Repair) on multihundredMHz to multiGHz clock domains.
• Expertise with industrystandard EDA flows: Scan insertion, ATPG, pattern simulation (gate-level), fault modeling, and diagnosis tools.
• Demonstrated proficiency with DFT flows: compression techniques, EDT, JTAG/IEEE 1149.1/1687, and managing large pattern sets.
• Proficiency using Python/Tcl scripting for DFT flow automation, pattern generation/management, and silicon debug/bring-up.
• Solid grounding in semiconductor device physics, fault models (stuck-at, transition, bridging), and yield enhancement strategies.
• Excellent communication and crossfunctional collaboration abilities; thrives in a fastmoving, ambiguous environment.
