Staff Firmware Engineer

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.

Tenstorrent is looking for a Staff Firmware Developer to contribute to development of system management firmware for Tenstorrent products, with strong familiarity across the broader system software stack (bootloaders, embedded Linux, drivers, and low‑level host integration). You’ll own critical pieces of our mission‑mode firmware running on embedded controllers and management cores, while collaborating closely with system software, validation, and hardware teams to deliver reliable, debuggable platforms.

This role is hybrid, based out of Toronto, ON.

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 have 5+ years of experience in embedded firmware or low-level system software development, with strong C/C++ fundamentals across memory layout, interrupts, concurrency, and bare-metal or RTOS-based development.

• You have hands-on experience bringing up hardware platforms and debugging issues at the hardware-software boundary using lab and software tools.

• You are comfortable working across the broader system stack, including bootloaders, embedded Linux, drivers, host management interfaces, and firmware validation workflows.

• You collaborate effectively across hardware, validation, and software teams, and ideally bring added experience in areas such as Zephyr, power and thermal management, secure boot, CI, or Python-based automation.
