Job Title: Senior DFT Engineer

Experience Level: 5+ 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 5+ 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 5+ 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.
- Solid 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.
