Staff Physical Design Engineer – Emir

Tenstorrent · Semiconductors · Austin, Fort Collins +1 · Physical Design

This role focuses on the physical design and EMIR (Electromigration and IR-drop) analysis for high-performance ICs, specifically for AI chips and RISC-V CPUs. The engineer will ensure robust power delivery, signal integrity, and long-term reliability, working with RTL and physical design teams on advanced technology nodes.

What you'd actually do

  1. Lead EM and IR-drop simulations to ensure robust power delivery, signal integrity, and long-term reliability for high-performance ICs.
  2. Work with RTL, physical design, and analysis teams to implement power grid strategies that optimize performance, power, and area (PPA), particularly at advanced nodes like 7nm and below.
  3. Support EMIR sign-off and waiver methodologies across the chip hierarchy.
  4. Architect and analyze robust power delivery for Tenstorrent’s RISC-V CPUs and AI chips.
  5. Integrate EMIR signoff into fast-paced, high-performance chip design cycles.
