Job Title: Senior DFT Engineer

Experience Level: 10+ Years

Work Location: Bangalore, India

Domain: VLSI / Semiconductor / ASIC Design

Employment Type: Full time

Position Overview

We are seeking an experienced and self-driven Senior DFT (Design for

Testability) Engineer with 10+ years of hands-on experience to lead and execute block-level and chip-level DFT architecture, implementation,

pattern generation, and sign-off. The ideal candidate will possess deep expertise in scan insertion, ATPG, timing analysis, and industry-standard EDA tools, along with strong cross-functional coordination skills to drive high-quality silicon testability.

Key Roles & Responsibilities:

DFT Implementation & Architecture:

Lead end-to-end DFT activities at both Block level and Chip level,

including Scan insertion, compression setup, and boundary scan integration.

Define and implement DFT modes, constraints, and timing sign-off protocols.

ATPG & Pattern Generation:

Develop and deliver ATPG patterns across various fault models,

including Stuck-at (Nominal and VBOX), IDDQ, and Transition/At-Speed faults.

Analyze fault coverage metrics and implement strategies to drive continuous coverage improvement.

Validation & Timing Sign-off:

Perform pattern validation with and without timing (Gate-Level

Simulations / GLS) to ensure zero failure rates prior to tape-out.

Perform DFT mode timing analysis, setup/hold fixing, and formal verification/sign-off.

Cross-Functional Collaboration:

Partner closely with RTL Integration, Synthesis, Static Timing

Analysis (STA), and Physical Design teams to identify, debug,



and resolve cross-functional dependencies and timing bottlenecks.

Post-Silicon & Advanced Architecture (Desirable):

Support MBIST (Memory Built-In Self-Test) design and integration.

Assist in post-silicon bring-up, silicon debug, and failure analysis for test-related issues.

Required Qualifications & Technical Skills:

Education & Experience

Education: Bachelor's or Master's degree in Electrical/Electronics

Engineering, Microelectronics, VLSI Design, or a related discipline.

Experience: Minimum 3+ years of hands-on industry experience in DFT execution for complex SoC/ASIC projects.

Tool Chain Expertise

Must have hands-on proficiency with major industry EDA toolsets:

Synopsys: DFT MAX, TetraMAX, VCS

Cadence: Genus, Modus, Xcelium

Siemens / Mentor Graphics: Tessent Toolchain, TestKompress

Technical Competencies

Proven experience in generating scan patterns and coverage statistics for Stuck-at, IDDQ, and Transition fault models.

Deep understanding of scan architectures, pattern compression techniques, and fault classification.

Strong scripting skills in TCL and Perl for automating flow execution and data parsing.

Working knowledge of MBIST and exposure to Post-Silicon Debug is a strong plus.

Core Competencies & Soft Skills:

Problem-Solving & Debugging: Advanced root-cause analysis skills for complex timing, simulation, and pattern failures.

Communication: Clear and effective communication skills to collaborate seamlessly with multi-site and cross-functional teams.

Project Ownership: Goal-oriented, highly focused mindset with a strong commitment to meeting strict project milestones and achieving high-quality closure.
