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 Firmware Engineer working on microcontrollers and SoCs, focused on low-level C/C++ development and board bring-up. You’ll implement and debug firmware, develop boot/power/reset sequences, and use lab tools to diagnose issues across the hardware–software boundary. You’ll collaborate closely with hardware, board, and system software teams while building strong skills in modern embedded platforms, RTOS/Embedded Linux, and automated testing. This role is hybrid, based out of Toronto, Canada. 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 • An experienced embedded engineer with a strong foundation in computer engineering, electrical engineering, computer science, or a related field, and a track record of building reliable software for real-world systems. • A strong problem solver who enjoys working where software meets hardware and can move comfortably between architecture, implementation, debugging, and system-level thinking. • Curious by nature and energized by complex challenges, with a willingness to explore new technologies, development approaches, and AI-assisted tools to make engineering more effective. • A thoughtful technical contributor who communicates clearly, collaborates well across disciplines, and brings a mindset of ownership, continuous improvement, and engineering excellence. What We Need • Technical leadership across the firmware development lifecycle, from early architecture and platform bring-up through validation, production, and continued improvement. • Engineers who can take on ambiguous and technically challenging problems, develop practical solutions, and make thoughtful tradeoffs with reliability, performance, scalability, and maintainability in mind. • A strong advocate for quality and collaboration who contributes to design reviews, testing strategies, engineering standards, and mentorship while helping the broader team grow. • A hands-on mindset and a willingness to dig deep when things don't work, bringing together software, hardware, and system-level perspectives to find the root cause and move the product forward. What You Will Learn • The opportunity to work on challenging embedded systems from early development through production, gaining a broader perspective of how hardware and software come together to create reliable products. • Deeper exposure to system architecture, platform development, debugging, validation, and the decisions that shape products well beyond an individual feature or component. • Modern approaches to embedded engineering, including automation, continuous integration, advanced testing, collaborative development practices, and emerging AI-powered tools. • Opportunities to expand technical influence through mentorship, cross-functional collaboration, architectural thinking, and ownership of initiatives that make a lasting impact on the team and product. Tenstorrent offers a highly competitive compensation package and benefits, and we are an equal opportunity employer. This offer of employment is contingent upon the applicant being eligible to access U.S. export-controlled technology. Due to U.S. export laws, including those codified in the U.S. Export Administration Regulations (EAR), the Company is required to ensure compliance with these laws when transferring technology to nationals of certain countries (such as EAR Country Groups D:1, E1, and E2). These requirements apply to persons located in the U.S. and all countries outside the U.S. As the position offered will have direct and/or indirect access to information, systems, or technologies subject to these laws, the offer may be contingent upon your citizenship/permanent residency status or ability to obtain prior license approval from the U.S. Commerce Department or applicable federal agency. If employment is not possible due to U.S. export laws, any offer of employment will be rescinded.
