Midcore CPU Performance Architect

United States

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 CPU Architect to take the lead on the design and optimization of the Midcore Unit (MC) in our high-performance, out-of-order RISC-V CPUs. This is a hands-on architecture role with real impact—you’ll be shaping the performance-critical instruction scheduling and execution units in the CPU. You'll work alongside some of the industry's best minds in high-performance computing and CPU micro-architecture.

This role is remote, based out of the United States.

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 have a strong grasp of CPU microarchitecture fundamentals, especially around instruction scheduling, register files, scalar and vector execution, and optimizing instruction execution latencies.
  • You have worked with performance simulation tools like Gem5 or SimpleScalar and are comfortable analyzing system bottlenecks and tuning performance.
  • You’re collaborative, organized, and enjoy bridging architectural ideas with hands-on modeling and analysis.
  • Familiarity with HDLs (Verilog, VHDL) and low-level C/C++ programming is a plus—not required, but helpful in collaborating with design and software teams

 

What We Need

  • Drive the architecture and microarchitecture of the midcore unit for our out-of-order RISC-V CPUs.
  • Model, simulate, and evaluate mid-core performance and PPA (power, performance, area) tradeoffs, including novel cross-unit instruction scheduling and execution techniques.
  • Propose and prototype new approaches to optimize scheduling and execution paths and improve instruction/data throughput.
  • Collaborate with software, RTL, and performance modeling teams to close the loop on real-world performance.

 

What You Will Learn

  • How to architect high-throughput, low-latency general purpose, AI, and HPC workloads that scale across chiplets and cores.
  • How to model and optimize CPU behavior across different instruction-mix patterns and workloads.
  • How Tenstorrent blends RISC-V extensibility with custom microarchitecture to push boundaries in high-performance CPU design.
  • How cutting-edge CPU teams deliver innovative performance features from architecture spec to implementation and validation.

 

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.

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.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
