DFT Engineer

Job Title

DFT Engineer

Role Summary

Work on mixed-signal audio SoC designs as part of the ASIC development team in Austin. The role focuses on design-for-test (DFT) implementation, memory BIST and scan insertion, ATPG and verification, and delivering validated test patterns for production test and silicon bring-up.

Experience Level

Mid-level. The team expects candidates with practical ASIC DFT experience; typical hires meet or exceed 2 years of relevant industry experience.

Responsibilities

Primary responsibilities include planning and implementing DFT features and producing validated test patterns for product test and bring-up.

• Define, implement, and review DFT features within the project team.
• Generate, insert, and verify memory BIST logic.
• Perform scan insertion and ATPG pattern generation.
• Develop and review DFT timing and equivalence-checking constraints.
• Verify MBIST and ATPG patterns with gate-level simulations.
• Identify and close test coverage gaps; perform test cost planning and analysis.
• Deliver MBIST and ATPG patterns to product test group and support ATE silicon bring-up.

Requirements

Must-have technical skills and experience for successful performance in the role.

• Hands-on ASIC DFT design and verification experience.
• Experience with industry DFT EDA tools (examples: FastScan, TestKompress, TetraMAX, Test Compiler).
• Practical experience with MBIST insertion and verification, scan insertion, ATPG pattern generation, and gate-level verification.
• Familiarity with DFT timing and equivalence-checking constraints and with test coverage analysis.
• Experience supporting delivery of patterns to test groups and ATE silicon bring-up.

Nice-to-have skills and behaviors.

• Experience with Verilog, SystemVerilog, or VHDL.
• Understanding of low-power test techniques and architectures.
• Scripting experience (Perl, Python, Tcl) and experience with flows and automation.
• Familiarity with synthesis, static timing analysis, and developing timing constraints.
• Experience debugging and root-causing silicon problems; strong oral and written communication; able to work independently and in a team.

Education Requirements

MSEE with 2+ years of industry experience, or BS with relevant industry experience.
