Key job responsibilities
As a DFT Engineer at Annapurna Labs (AWS), you'll take ownership of testability architectures and DFT logic, driving their development and verification through the full hardware lifecycle. Your responsibilities may include:

• Define and implement DFT architectures for complex SoC designs
• Develop and integrate DFT logic including: MBIST (Memory Built-In Self-Test), JTAG/TAP, and boundary scan
• RTL coding and debug of DFT controllers and infrastructure using Verilog/SystemVerilog
• Drive gate-level simulations to validate DFT functionality and test patterns
• Develop and verify DFT logic using UVM-based testbenches, functional simulation, and coverage-driven verification
• Participate in design reviews, DFT sign-off processes, and tapeout preparation
• Cross-functional collaboration with Design, Verification, Physical Design, and Production/Test teams
