Test Engineer, System-Level Test (SLT)

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 hiring a System-Level Test (SLT) Engineer to ensure our silicon behaves predictably when running real workloads in real systems. You’ll build the software and system infrastructure that enables validation tests to operate reliably in manufacturing, while applying structured debug to separate hardware issues from software, interface, and environmental effects. This role is ideal for someone who understands how tests are constructed and how silicon responds under stress—and who can turn that insight into scalable, production-ready solutions. Candidates will be assessed for the appropriate level during the interview process, and the offer level may differ from the level listed in this posting. This role is hybrid, based out of Austin,TX; Santa Clara,CA; or Fort Collins, CO . 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 10+ years of experience in system-level test, embedded systems, software architecture, or hardware/software integration, with strong skills in C/C++, Python, or similar languages. You apply object-oriented design principles to build modular, maintainable, and extensible test frameworks, including execution wrappers, harnesses, and abstraction layers. You can control test equipment and automate handlers or external instruments through standard communication protocols, while debugging across test hardware, Linux hosts, firmware, drivers, and operating systems. You collaborate effectively across validation, firmware, silicon debug, product engineering, manufacturing, and OSAT/fab teams; experience with JTAG, boundary scan, DFT, high-volume manufacturing, NPI, Git, or CI/CD is a plus. What We Need Develop the test execution framework that hosts validation-provided tests in SLT environments deployed to OSAT production. Build wrappers, harnesses, and abstraction layers that run validation content unmodified while providing deterministic execution, dependency management, configuration control, and structured error handling. Integrate functional, stress, and diagnostic tests into SLT platforms; adapt them for high-volume manufacturing with stable execution and clear…
