DFT Engineer

Job Title

DFT Engineer

Role Summary

The DFT Engineer will develop and verify design-for-test features for mixed-signal audio SoCs used in consumer mobile audio products. The role sits on the mixed-signal audio development team and focuses on memory BIST, scan insertion, ATPG, coverage improvement, and delivering test patterns to product test and ATE teams.

Experience Level

Entry-level — typically requires around 2+ years of industry experience (see Education Requirements for degree guidance).

Responsibilities

Key responsibilities include DFT implementation, verification, and test delivery:

• Define, implement, and review DFT features within a cross-functional team.
• Generate, insert, and verify Memory BIST logic.
• Perform scan insertion and ATPG pattern generation and verification (including gate-level sims).
• Develop and review DFT timing and equivalence checking constraints.
• Identify coverage gaps and implement improvements.
• Perform test cost planning and analysis.
• Deliver MBIST and ATPG patterns to product test and support silicon bring-up on ATE.

Requirements

Must-have technical skills and constraints:

• Hands-on experience with ASIC DFT design and verification.
• Experience with industry-standard DFT/ATPG/MBIST tools such as FastScan, TestKompress, TetraMAX, Test Compiler, or similar.
• Experience with MBIST and ATPG pattern verification using gate-level simulation.
• Ability to perform test cost planning and deliver test patterns to production test groups.
• Must be able to access technical data without a requirement for an export license; employer cannot sponsor export licenses for this role.

Nice-to-have:

• Experience with Verilog, SystemVerilog, or VHDL.
• Understanding of low-power test techniques and architectures.
• Scripting skills (Perl, Python, TCL) and experience with flows and automation.
• Experience with synthesis, static timing analysis, and developing timing constraints.
• Experience debugging and root-causing silicon issues; strong written and oral communication skills.

Education Requirements

M.S.E.E. with 2+ years of relevant experience, or a B.S. with relevant industry experience (as stated in the posting).
