Job Description

Job Title: Senior DFT Engineer (Architecture & Implementation)
Location: Bengaluru
Experience: 5+ Years
About the Mission At Best NanoTech, we are building the silicon engines of the future. Whether it's AI accelerators or autonomous driving processors, our chips are massive and complex. Our DFT team is responsible for ensuring that every transistor we print works exactly as intended. We are looking for a Senior Engineer to lead DFT implementation and drive yield improvement.
The Role As a Senior DFT Engineer, you will own the testability logic from architecture to post-silicon. You will work closely with RTL designers to make the design testable without compromising performance.
Key Responsibilities:

• Architecture: Define DFT architecture specifications including Scan, MBIST (Memory BIST), Boundary Scan, and IP test logic.
• Insertion & Verification: Perform Scan insertion, DRC analysis, and simulation verification at block and top levels.
• Pattern Generation: Generate high-coverage ATPG patterns (Stuck-at, Transition, Path Delay) and minimize test time using compression techniques.
• Standards: Implement standard test interfaces like JTAG (IEEE 1149.1), iJTAG (IEEE 1687), and Core Wrapper (IEEE 1500).
• Low Power: Handle DFT in complex low-power designs (UPF/CPF), ensuring isolation and level shifters are correctly handled during test modes.
• Post-Silicon: Collaborate with the Product Engineering team on ATE pattern bring-up, diagnosis of fail logs, and yield enhancement.

What You Bring (Requirements)

• Experience: 5-10 years of hands-on experience in DFT for complex SoCs.
• Tool Proficiency: Expert-level knowledge of industry-standard tools: Siemens (Mentor) Tessent, Synopsys TestMAX/SMS, or Cadence Modus.
• Protocols: Deep understanding of JTAG, IJTAG, and high-speed I/O testing.
• Scripting: Strong proficiency in Tcl, Perl, or Python to automate flows and parse reports.
• Simulation: Experience with logic simulators (VCS/Questasim) for debugging pattern mismatches.

Nice to Have

• Experience with Analog/Mixed-Signal (AMS) testing.
• Knowledge of Functional Safety (ISO 26262) for automotive chips.
• Experience with 2.5D/3D-IC testing standards.
