Design-for-Test (DFT) Engineer

This role is for one of the Weekday's clients

Salary range: Rs 1500000 - Rs 8000000 (ie INR 15 - 80 LPA)

Min Experience: 5+ years

Location: Bengaluru, Telangana, Hyderabad, Telangana, India, Karnataka

JobType: full-time

We are seeking an experienced DFT Engineer with 5–20 years of industry experience to drive the design-for-test strategy and implementation for complex ASIC/SoC designs. The ideal candidate will have strong hands-on expertise in ATPG and Scan, with a solid understanding of test architecture, fault coverage, test pattern generation, and DFT verification.

You will work closely with RTL, Physical Design, Verification, and Product Engineering teams to develop robust, production-ready test solutions while ensuring high test coverage, quality, and manufacturability.

Requirements

Key Responsibilities

• Define and implement DFT architectures for complex ASIC/SoC designs.

• Develop and integrate Scan-based DFT structures across blocks and top-level designs.

• Develop, run, and debug ATPG flows for stuck-at, transition, and other relevant fault models.

• Analyze ATPG coverage, fault reports, pattern quality, and test compression results.

• Debug ATPG failures and identify design, constraint, or test-logic issues.

• Work with RTL and design teams to resolve DFT-related implementation and verification issues.

• Perform DFT rule checks and ensure test structures meet project requirements.

• Support scan insertion, scan-chain verification, chain balancing, and scan connectivity checks.

• Collaborate with physical design teams to ensure DFT structures are physically implementable and timing-aware.

• Support DFT verification from block level through full-chip integration.

• Develop and maintain DFT methodologies, scripts, and automation to improve design and test efficiency.

• Participate in test architecture reviews and contribute to improving test coverage, quality, and overall silicon readiness.

• Support post-silicon debug and analysis of test-related issues when required.

Must-Have Skills

• 5–20 years of hands-on experience in DFT/ASIC design and test engineering.

• Strong expertise in ATPG (Automatic Test Pattern Generation).

• Extensive experience with Scan architecture and Scan insertion.

• Strong understanding of scan chains, scan compression, test modes, and test coverage.

• Experience debugging ATPG patterns, coverage issues, and DFT rule violations.

• Good understanding of ASIC/SoC design flows and DFT implementation methodologies.

• Experience working with RTL, synthesis, verification, and physical design teams.

• Strong scripting/automation skills using languages such as Tcl, Python, or Perl.

Good-to-Have Skills

• Experience with SSN (Serial Scan Network) and related test architectures.

• Knowledge of PDL (Procedure Description Language) and IEEE 1687/IJTAG concepts.

• Experience with DRC (Design Rule Checks) for DFT/test structures.

• Exposure to memory BIST, logic BIST, boundary scan, test compression, and IEEE 1149.x standards.

• Experience with industry-standard DFT/ATPG tools and methodologies.

• Understanding of timing, power, and physical-design considerations for scan and ATPG.

• Experience with advanced SoC designs and hierarchical DFT implementation.

What We’re Looking For

The ideal candidate is a technically strong DFT professional who can independently own DFT activities, troubleshoot complex test challenges, and collaborate effectively across multiple engineering teams. Strong analytical, debugging, communication, and problem-solving skills are essential for success in this role.
