Principal Engineer – DFT (Design for Test)
Location: Bengaluru, India
Experience: 12–18 Years
About the Role
We are seeking a Principal Engineer – DFT to lead the architecture, implementation, and signoff of Design-for-Test solutions for complex, high-performance SoCs. You will drive end-to-end DFT strategy, collaborate with Architecture, RTL, Physical Design, and ATPG teams, and ensure high test quality, manufacturability, and first-pass silicon success across advanced technology nodes.
Key Responsibilities
Define and drive the DFT architecture for complex SoCs from specification to silicon.
Own end-to-end DFT implementation, including Scan Insertion, Scan Compression, MBIST, LBIST, JTAG (IEEE 1149.1/1500), Boundary Scan, and TAP Controller integration.
Develop and validate DFT specifications, test modes, and test access mechanisms.
Generate and optimize ATPG patterns for stuck-at, transition, path-delay, bridge, and cell-aware fault models.
Drive test coverage closure, pattern optimization, diagnosis, and silicon bring-up support.




Collaborate with Physical Design teams on scan chain reordering, DFT-aware timing closure, and DRC cleanup.
Work closely with RTL and Verification teams to ensure DFT functionality through simulation and formal verification.
Develop DFT automation flows and improve methodology using Tcl, Python, or Perl.
Mentor engineers and provide technical leadership across DFT execution.
Required Qualifications
12–18 years of hands-on experience in Design for Test (DFT) for complex ASIC/SoC designs.
Strong expertise in Scan Insertion, Scan Compression, ATPG, MBIST, LBIST, JTAG/TAP Controller, and Boundary Scan.
Extensive experience with Mentor Tessent or equivalent DFT tool suite.
Strong knowledge of fault models, test coverage analysis, pattern generation, and diagnosis.
Valuable understanding of Physical Design, STA, scan timing, and DFT signoff.
Experience with advanced technology nodes (7nm/5nm/3nm) is highly preferred.
Proficiency in Tcl, Python, or
