CPU Workload Performance Analysis Engineer

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.

We are looking for a highly-skilled CPU Workload Performance Analysis Engineer to drive workload characterization, performance simulation, and in-depth performance analysis for cutting-edge CPU products. In this role, you will collaborate closely with CPU architects, RTL designers, and software engineers to reduce real-world applications for performance modeling, analyze workload characteristics, identify and resolve performance bottlenecks, and optimize performance-per-watt efficiency. Your work will directly influence the design and implementation of next-generation high-performance computing platforms across diverse workloads.

This role is open to Santa Clara, CA, Austin, TX, Boston, MA, Toronto, ON, Ottawa, ON, or open to Remote in North America

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.

 

Responsibilities:

  • Conduct competitive analysis of the latest CPU products using industry-standard benchmarks and emerging applications.
  • Characterize CPU workloads, identifying performance bottlenecks and power inefficiencies in hardware and software interactions.
  • Collaborate with CPU architects and RTL designers to enhance microarchitectural features and improve performance/watt metrics.
  • Reduce workloads for CPU performance modeling, FPGA emulation, and model-to-RTL correlation.
  • Utilize performance models, EDA frameworks, and profiling tools to measure, characterize, and predict CPU performance and power under various workloads.
  • Stay up to date with industry trends, new workload requirements, and advancements in CPU microarchitecture and performance analysis techniques.

 

 

Experience & Qualifications:

  • Ph.D. in Computer Engineering, Electrical Engineering, or a related field.
  • Strong research background or industry expertise in benchmark construction, workload characterization, workload reduction, and performance simulation.
  • Proficiency in performance profiling tools such as Linux Perf, Strace, AMD’s uProf, Arm’s Telemetry Solution, or similar tools.
  • Deep understanding of CPU microarchitecture concepts, including superscalar pipelines, speculative execution, SIMD, and memory hierarchy.
  • Strong knowledge of operating system internals, runtimes, compilers, and GNU libraries.
  • Proficiency in C/C++, intrinsic/assembly programming, and scripting languages such as Python and Shell.
  • Excellent problem-solving and communication skills and the ability to work across multidisciplinary teams.
  • Experience with Ansible automation and GitLab CI is a plus.
  • Experience with GCC or LLVM compiler optimization is a plus
  • Familiarity with HPC and cloud virtualization is a plus.

 

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.

Due to U.S. Export Control laws and regulations, Tenstorrent is required to ensure compliance with licensing regulations when transferring technology to nationals of certain countries that have been licensing conditions set  by the U.S. government.

Our engineering positions and certain engineering support positions require access to information, systems, or technologies that are subject to U.S. Export Control laws and regulations, please note that citizenship/permanent residency, asylee and refugee information and/or documentation will be required and considered as Tenstorrent moves through the employment process.

If a U.S. export license is required, employment will not begin until a license with acceptable conditions is granted by the U.S. government.  If a U.S. export license with acceptable conditions is not granted by the U.S. government, then the offer of employment will be rescinded.

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.

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.
