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. Experienced engineer focused on Fabric / Memory Subsystem verification for high-performance CPUs. The person coming into this role will work on a server class Fabric unit. We have openings across multiple levels; once interviews have been completed, we will align your background with the appropriate engineering level. This role is hybrid, based out of Boston, MA or Toronto, Ontario. Responsibilities: * Functional and performance verification of the Fabric unit for a from-scratch high performance CPU while working closely with Architecture and RTL team * Develop detailed block level verification plans for a high-performance Fabric * Design and develop reusable block level testbench components in SV, UVM and C++, that include microarchitectural models, monitors, checkers * Develop random and directed stimulus that spans pre-silicon, emulation and post-silicon domain * Evaluate and integrate open-source toolchains into the DV flow * Develop DV environment, tools and infrastructure to enable functional verification for pre-silicon, emulation and post-silicon * Work with design, test and post silicon validation teams to ensure high quality delivery of the Fabric / Mem Subsystem block Experience and qualifications: * BS/MS/PhD in EE/ECE/CE/CS with at least 5 years of experience Strong background and experience with high performance OOO CPU microarchitecture especially with load/store, caches and memory subsystem * Experience working on a Fabric for a CPU or GPU based system. Knowledge of industry standard protocols such as CHI, AXI, ACE, Tilelink, CMN * Architectural understanding of memory ordering, cache coherency protocols, memory consistency, multi-processors and fabric topologies * Significant experience debugging RTL and DV in a simulation environment * Verification methodologies and techniques - Simulation/debug, TB development, stimulus, checking, coverage, infrastructure, tools * Experience with C++ / SV / UVM as well as scripting languages * Experience with hardware description languages (Verilog, VHDL) and simulators (VCS, NC, Verilator) * Strong problem solving and debug skills across various levels of design hierarchies Compensation for all engineers at Tenstorrent ranges from $100k - $500k including base and variable compensation targets. Experience, skills, education, background and location all impact the actual offer made. Tenstorrent offers a highly competitive compensation package and benefits, and we are an equal opportunity employer.
