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. Tenstorrent is looking for a Formal Verification Engineer to help ensure the correctness of our next generation of high-performance RISC-V CPUs and AI compute platforms. You’ll use formal methods to prove complex hardware behavior, uncover corner cases that simulation may miss, and give architects and RTL designers confidence in the correctness of their designs. You’ll work closely with CPU architects, RTL designers, and other DV engineers to develop properties, build formal verification environments, analyze failures, and drive issues to closure. This is a hands-on opportunity to apply formal techniques to challenging problems in modern processor design. This role is remote, based out of North America or Spain.

Who You Are

• - A verification engineer who enjoys solving complex problems and finding bugs that are difficult to expose through traditional simulation.
• - Comfortable thinking about hardware behavior in terms of properties, invariants, assumptions, assertions, and proofs.
• - A strong debugger who can analyze counterexamples, understand RTL behavior, and determine the root cause of failures.
• - Collaborative and curious, with an interest in working closely with architects and RTL designers to improve design quality.
• - Excited by the challenges of verifying high-performance CPUs and complex digital hardware.

What We Need

• - 6+ years of experience in design verification, formal verification, or related RTL verification for CPUs, SoCs, ASICs, or complex digital designs.
• - Hands-on experience with formal verification methodologies and tools, including property checking, assertions, assumptions, constraints, and coverage analysis.
• - Strong SystemVerilog skills, including experience writing and debugging SVA.
• - Solid understanding of digital design and computer architecture; experience with CPU pipelines, caches, interfaces, control logic, or other complex microarchitecture is highly valuable.
• - Strong programming and scripting skills in Python, Tcl, C/C++, or similar, with excellent debugging and problem-solving abilities.

What You Will Learn

• - Gain deep experience applying formal verification to high-performance, out-of-order RISC-V CPU designs.
• - Learn how to identify which hardware behaviors are best verified through formal methods versus simulation, emulation, and other DV techniques.
• - Develop expertise in writing scalable properties and proofs for complex control logic and interacting microarchitectural blocks.
• - Learn how architectural intent translates into formal properties, assumptions, and measurable verification goals.
• - Work alongside world-class CPU architects and RTL engineers on next-generation processors for AI, HPC, and high-performance computing.
