Job summary

Tenstorrent Inc. in Bengaluru, India seeks an experienced CPU verification engineer to own core verification and drive functional verification for advanced RISC-V CPU features.

You will develop UVM-based stimulus, assembly, and C/C++ models, and debug regressions using RTL, waveforms, and logs. The role is hybrid, based out of Bangalore, with opportunities across design, validation, and test teams to deliver robust CPU cores and clusters.

Qualifications

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

Responsibilities

• Own CPU core‑level verification and shape CPU behavior in silicon.
• Develop and maintain stimulus, models, and coverage for the CPU and ISA extensions.
• Troubleshoot regressions across RTL, simulation, and emulation environments.
• Collaborate with cross‑functional teams to ensure robust bring‑up of CPU cores and clusters.

Job description

Tenstorrent is leading the industry on cutting-edge AI technology, revolutionizing performance expectations, ease of use, and cost efficiency. With AI redefining the computing paradigm, solutions must evolve to unify innovations in software models, compilers, platforms, networking, and semiconductors. Our diverse team of technologists have developed a high performance RISC-V CPU from scratch, and share a passion for AI and a deep desire to build the best AI platform possible. We value collaboration, curiosity, and a commitment to solving hard problems. We are growing our team and looking for contributors of all seniorities.

At Tenstorrent, we build open, state of the art compute for real workloads and real developers.You will own CPU core‑level verification, shaping how our out‑of‑order RISC‑V CPUs behave in silicon.

This role ishybrid, based out of Bangalore, India.

We welcome candidates at various experience levels for this role. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this posting.

Who You Are

• You bring 8+ years in CPU verification or closely related digital design.
• You work comfortably with RTL, waveforms, logs, and complex debug scenarios.
• You communicate clearly across design, DV, emulation, and post‑silicon teams.

What We Need

• Plan and drive functional verification for CPU core features and complex microarchitectural scenarios.
• Develop UVM, assembly, and C/C++ based stimulus, functional models, and coverage for ISA, RISC-V extensions, and un-core components.
• Debug simulation and emulation regressions using RTL understanding, waveforms, and logs to identify and resolve issues efficiently.
