DFT engineers

This role is for one of Weekday’s clients

Min Experience: 4+ years

Location: Hyderabad, Bengaluru, Karnataka, India

JobType: full-time

We are looking for a skilled and experienced DFT Engineer with 4-12 years of experience in semiconductor design and test methodologies. The ideal candidate will have strong hands-on expertise in ATPG and Scan Insertion, with a solid understanding of DFT architecture, testability requirements, and silicon validation. Experience with MBIST will be an added advantage.

You will work closely with RTL design, physical design, verification, and product engineering teams to develop and implement robust DFT solutions for complex SoCs and ASICs. The role involves driving DFT implementation from architecture and insertion through ATPG generation, pattern validation, coverage analysis, and production readiness.

Requirements

Key Responsibilities

• Develop and implement DFT architectures and methodologies for ASIC/SoC designs.
• Perform scan insertion across hierarchical and full-chip designs while ensuring design integrity and testability.
• Develop, configure, and debug ATPG environments for stuck-at, transition, and other applicable fault models.
• Generate, validate, and optimize ATPG patterns to achieve high fault coverage and efficient test application.
• Analyze ATPG results, identify coverage gaps, and implement corrective measures to improve test coverage.
• Work on scan chain configuration, stitching, balancing, and verification.
• Debug DFT-related issues across RTL, gate-level netlists, and post-synthesis/post-layout stages.
• Collaborate with RTL, synthesis, physical design, STA, verification, and validation teams to resolve DFT implementation challenges.
• Review DFT constraints and ensure compatibility with synthesis and physical implementation flows.
• Perform DFT rule checks, identify violations, and support their closure.
• Analyze test coverage, pattern quality, test time, and compression requirements.
• Support gate-level simulations and debug test pattern failures.
• Contribute to improving DFT methodologies, automation scripts, and overall test efficiency.
• Support silicon bring-up and post-silicon debug when required.

Must-Have Skills

ATPG

• Strong hands-on experience with ATPG generation and pattern development.
• Good understanding of stuck-at, transition, and other fault models.
• Experience with ATPG coverage analysis, pattern debugging, and coverage improvement.
• Understanding of test compression and scan-based testing methodologies.

Scan Insertion

• Strong experience in scan insertion and scan chain implementation.
• Knowledge of scan architecture, scan stitching, chain balancing, and DFT rule checks.
• Experience debugging scan-related issues at RTL and gate level.
• Understanding of DFT constraints and their interaction with synthesis and physical design flows.

Good-to-Have Skills

MBIST

• Exposure to Memory Built-In Self-Test (MBIST) architecture and implementation.
• Understanding of memory test algorithms, controllers, and MBIST pattern generation.
• Experience integrating or validating MBIST solutions in SoC/ASIC designs.

Preferred Qualifications

• Bachelor's or Master's degree in Electronics, Electrical Engineering, VLSI, Microelectronics, or a related field.
• 4-12 years of relevant experience in DFT/ASIC/SoC development.
• Strong analytical and debugging skills with the ability to work across multiple design teams.
• Experience with industry-standard DFT/ATPG tools and semiconductor design flows is highly desirable.
• Good communication and collaboration skills, with the ability to work effectively in cross-functional engineering teams.
