DFT Engineer

This role is for one of the Weekday's clients

Salary range: Rs 700000 - Rs 2500000 (ie INR 7 - 25 LPA)

Min Experience: 3 years

Location: NCR, Bengaluru, Hyderabad

JobType: full-time

We are looking for a talented and detail-oriented DFT Engineer with 3-8 years of experience in Design-for-Test methodologies to join our semiconductor design team. The ideal candidate will play a key role in implementing and validating robust DFT architectures that ensure high manufacturing test coverage, improved product quality, and efficient silicon bring-up. You will work closely with RTL designers, verification engineers, physical design teams, and test engineers throughout the ASIC/SoC development lifecycle.

This role requires strong expertise in Automatic Test Pattern Generation (ATPG) and RTL, along with a solid understanding of scan insertion, fault modeling, and testability concepts. Experience with JTAG and boundary scan implementation will be an added advantage.

Requirements

Key Responsibilities

• Develop and implement DFT architectures for complex ASIC and SoC designs.
• Perform scan insertion, scan chain stitching, compression implementation, and DFT rule checks.
• Generate and optimize test patterns using ATPG tools to achieve high fault coverage while minimizing test time.
• Analyze stuck-at, transition, bridge, and path delay faults to improve manufacturing test quality.
• Collaborate with RTL designers to integrate DFT features early in the design cycle and ensure design-for-test compliance.
• Review and debug RTL code to resolve DFT-related issues and optimize testability.
• Validate DFT implementation through simulation, verification, and silicon bring-up activities.
• Work closely with physical design teams to ensure successful scan chain implementation and timing closure.
• Support post-silicon debug, yield improvement, and failure analysis by identifying root causes and implementing corrective actions.
• Maintain DFT documentation, test plans, and implementation guidelines while ensuring adherence to project milestones.

Required Qualifications

• Bachelor's or Master's degree in Electronics, Electrical Engineering, Computer Engineering, or a related discipline.
• 3-8 years of hands-on experience in DFT implementation for ASIC or SoC designs.
• Strong understanding of digital design principles and semiconductor design flow.
• Experience working in cross-functional engineering environments with the ability to solve complex technical challenges.

Must-Have Skills

• Strong expertise in Automatic Test Pattern Generation (ATPG), including test pattern generation, fault coverage analysis, pattern optimization, and debug.
• Solid experience with RTL design, debugging, and integration, with the ability to analyze and resolve DFT-related design issues.
• Good understanding of scan insertion, scan compression, scan chain verification, and DFT rule checking.
• Knowledge of fault models, test coverage metrics, and manufacturing test methodologies.
• Familiarity with industry-standard EDA tools used for DFT implementation and ATPG.

Good-to-Have Skills

• Experience with JTAG, IEEE 1149.x standards, boundary scan implementation, and debug.
• Exposure to MBIST, LBIST, memory repair techniques, or embedded test methodologies.
• Understanding of synthesis, static timing analysis, physical design constraints, and silicon validation.
• Familiarity with scripting languages such as Tcl, Perl, or Python for automation.
• Knowledge of low-power DFT techniques and compression technologies.
