CPU Verification Fellow, RISC-V High-Performance Processor

Who You Are

• You have deep experience verifying high-performance superscalar CPUs, ideally including out-of-order and speculative processors.
• You have strong knowledge of RISC-V architecture, including ISA compliance, privileged architecture, virtual memory, atomics, vector extensions, and memory model behavior.
• You are highly proficient in SystemVerilog, UVM, constrained-random verification, assertions, functional coverage, and advanced debug methodologies.
• You have hands-on experience with CPU reference models, instruction generators, ISS-based checking, or differential testing.
• You bring practical expertise with formal verification and large-scale CPU verification environments.

What We Need

• A verification leader who can own strategy for RISC-V high-performance superscalar CPUs and CPU subsystems.
• An expert who can drive verification planning for out-of-order, speculative, superscalar microarchitectures.
• A technical leader who can build and scale test plans, coverage, checkers, assertions, scoreboards, and constrained-random environments.
• Someone who can verify key CPU features including frontend, branch prediction, rename, scheduling, execution, load-store, memory ordering, cache hierarchy, retirement, exceptions, interrupts, debug, and coherency interactions.
• A cross-functional partner who can work closely with architecture, RTL, performance modeling, SoC, firmware, compiler, and validation teams while mentoring senior engineers and establishing best practices across the CPU verification organization.

What You Will Learn

• How Tenstorrent develops next-generation RISC-V high-performance superscalar processors from early design through tapeout and post-silicon validation.
• How CPU verification strategy scales across simulation, formal verification, emulation, FPGA prototyping, and silicon bring-up.
• How advanced CPU features such as coherency, virtual memory, atomics, vector extensions, and custom extensions are verified in complex real-world systems.
• How to drive verification closure, bug triage, root-cause analysis, coverage closure, and tapeout readiness at the highest levels of technical leadership.
• How Tenstorrent teams collaborate across architecture, design, firmware, compiler, and validation to build cutting-edge compute products.

Additional information

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.

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.
