Lead DFT Engineer

Lead DFT Engineer

Location: Bengaluru, India

Experience: 610 Years

Role Type: Full-time | Silicon Engineering

About the Role

We are seeking a Lead Design-for-Test (DFT) Engineer to drive RTL-centric DFT architecture and execution for complex SoCs and subsystems used in high-performance compute, AI acceleration, and advanced connectivity platforms.

You will own the complete DFT lifecycle from RTL insertion strategy through pattern generation, simulation, and silicon-quality coverage closure while partnering with design, physical implementation, and post-silicon teams to ensure first-pass success.

This role is ideal for engineers who combine deep hands-on DFT implementation with system-level thinking and execution excellence.

What Youll Do

• Lead RTL-level DFT architecture and implementation across full SoC and block/partition hierarchies
• Own DFT flows using Mentor Tessent across:
• Scan insertion
• MBIST
• OCC (on-chip clocking)
• EDT compression using ARM DFT flow
• Drive LEC (Logical Equivalence Check) at:
• RTL pre-DFT vs post-DFT
• RTL vs gate-level netlists
• Execute pattern generation, retargeting, and simulation at block and SoC level
• Perform zero-delay and timing-aware simulations using SDF back-annotation
• Drive coverage closure across stuck-at, transition, and memory faults
• Develop scan synthesis flows and timing constraints aligned with physical design requirements
• Partner with PD teams to ensure timing-clean DFT insertion
• Debug test failures through simulation and silicon correlation
• Mentor engineers and review DFT architecture across projects

Minimum Qualifications

• 610 years of hands-on DFT engineering experience in SoC environments
• Strong expertise in Mentor Tessent DFT tool flow
• Deep RTL-level implementation experience for:
• Scan
• MBIST
• OCC
• EDT compression (ARM DFT methodology)
• Proven experience across SoC and block/subsystem-level DFT
• Strong experience in:
• LEC flows (RTL post-DFT gate)
• Pattern generation, retargeting, and fault simulation
• Timing-aware simulation using SDF
• Coverage closure methodologies
• Solid understanding of scan synthesis and timing constraint development
• Strong RTL skills (Verilog/SystemVerilog)
• Bachelors or Masters degree in Electrical Engineering or related field

Preferred Qualifications

• Experience in advanced nodes (7nm and below)
• Post-silicon debug and yield learning exposure
• Strong scripting (TCL, Python) for flow automation
• Experience mentoring or leading small technical teams

Must-Have Domain Knowledge

• SSN (Simultaneous Switching Noise) analysis awareness and mitigation within DFT strategies

What Makes This Role Exciting

• Ownership of full DFT lifecycle not just insertion
• Exposure to large, complex SoC architectures
• Influence silicon quality at production scale
• Work with industry-leading DFT methodologies
• Fast-paced FAANG-style engineering culture

Your Impact

• Enable first-pass silicon success
• Achieve industry-leading test coverage
• Reduce test cost through smart compression strategies
• Build scalable RTL-first DFT frameworks
