Job summary

positron.ai is seeking a hands-on Lead DFT engineer to drive test-for-chip strategy for custom AI accelerators. You will own DFT architecture from RTL through tapeout, coordinating with backend teams and performing pre-silicon validation, simulation, and verification.

You will implement scan insertion, ATPG, memory BIST, boundary scan, and IJTAG, while planning test coverage and collaborating across RTL, synthesis, and physical design to ensure a successful silicon bring-up.

Qualifications

• Significant hands-on experience implementing DFT for complex ASICs or SoCs.
• Experience with RTL, synthesis, DFT tools, and simulation or gate-level verification.
• Ability to collaborate with backend teams and carry DFT work through tapeout.

Responsibilities

• Design and implement scan, compression, ATPG, memory BIST, boundary-scan, IJTAG, and debug or observability features.
• Integrate DFT logic into internal RTL and assess test capabilities in third-party IP.
• Develop verification plans and validate DFT behavior through simulation and gate-level checks.
• Plan stuck-at, transition, cell-aware, and power-aware ATPG strategies and meet test coverage goals before tapeout.
• Work with physical design teams on scan-chain partitioning, compression, test clocks, and physical implementation.
• Support silicon test and bring-up, investigating issues and improving test readiness.
