Staff Design for Test Engineer

Tenstorrent · Semiconductors · Austin, TX · Silicon

Tenstorrent is seeking a Staff Design for Test Engineer to work on high-performance AI/ML architectures. The role involves all implementation aspects from RTL to tapeout, focusing on reducing test cost, attaining high coverage, and facilitating debug and yield learnings. Responsibilities include implementing DFT features, owning ATPG and test coverage analysis, planning and verifying MBIST, and developing DFx flows.

What you'd actually do

  1. Implement and integrate DFT features (scan, JTAG, compression, ASST, MBIST) into RTL from early design through tapeout across multiple IPs.
  2. Own ATPG, test coverage analysis, and gate-level simulation (e.g., with Synopsys VCS/Verdi) to achieve and maintain high-quality test coverage.
  3. Plan, implement, and verify MBIST, and work closely with Test Engineering on test planning, pattern delivery, and debug.
  4. Develop and refine DFx flows and methodology that integrate cleanly with front-end and physical design flows, balancing coverage, test cost, and design intrusiveness.
