ASIC DFT Engineer

Job Title

ASIC DFT Engineer

Role Summary

Join the Common Hardware Group within the Silicon One development organization as an ASIC Design-for-Test (DFT) Engineer. The role drives DFT requirements and integration across front-end RTL, back-end physical design, implementation, and post-silicon validation for high-performance networking ASICs.

Experience Level

Senior — requires 7+ years of relevant industry experience.

Responsibilities

The engineer will define, implement, and validate DFT solutions across the full chip lifecycle.

• Specify and implement hardware DFT features supporting ATE, in-system test, debug and diagnostics.
• Develop and integrate DFT IP with RTL and full-chip design flows.
• Collaborate with RTL design, design-verification, and physical design teams to enable test logic integration and validation during implementation and post-silicon phases.
• Drive reusable test and debug strategies for new device models (bare die, stacked die).
• Lead DFT and quality processes through implementation signoff and post-silicon validation.
• Debug complex silicon/test failures with minimal supervision.

Requirements

Must-have technical skills and experience.

• 7+ years of industry experience in DFT, test, or silicon engineering.
• Hands-on experience with JTAG protocols, scan architectures, and BIST (including memory BIST and boundary scan).
• Practical experience with ATPG and EDA tools such as TestMax, Tetramax, Tessent tool sets, and PrimeTime.
• Gate-level simulation and debugging experience using simulators (e.g., VCS).
• Post-silicon validation and debug experience, including work with ATE patterns and P1687.

Nice-to-have / preferred:

• Verilog experience for custom DFT logic and IP integration.
• DFT CAD development experience: test architecture, methodology, and infrastructure.
• Test static timing analysis (Test STA) expertise.
• SystemVerilog skills for logic equivalency checking and validating test timing.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering or Computer Engineering is required (as stated in the posting).
