Staff Engineer, Cpu Core Verification

Tenstorrent Tenstorrent · Semiconductors · Bangalore, India · RISC V

Tenstorrent is seeking a Staff Engineer for CPU Core Verification to own CPU core-level verification and shape how out-of-order RISC-V CPUs behave in silicon. Responsibilities include planning and driving functional verification, developing stimulus and coverage, debugging regressions, and collaborating with cross-functional teams.

What you'd actually do

  1. Plan and drive functional verification for CPU core features and complex microarchitectural scenarios.
  2. Develop UVM, assembly, and C/C++ based stimulus, functional models, and coverage for ISA, RISC-V extensions, and un-core components.
  3. Debug simulation and emulation regressions using RTL understanding, waveforms, and logs to identify and resolve issues efficiently.
  4. Build and enhance coverage models, testbenches, and debug infrastructure to improve verification quality and coverage closure.
  5. Collaborate with design, validation, and test teams to support bring-up and delivery of robust CPU cores and clusters.
