Engineer, Validation- GDDR7

Toronto, Ontario, Canada

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.

At Tenstorrent, we’re building the next generation of AI/ML hardware platforms, and next generation high speed memory is a key enabler of our performance and scalability. We are looking for a GDDR7 IP Validation and Firmware Engineer to work on the validation and enablement of our next-gen GDDR7 PHY and controller IP. In this role, you will own the post-silicon validation of high-speed memory interfaces, do low-level firmware development for bring-up and diagnostics, and work closely with cross-functional teams and memory vendors to deliver robust and high-performance memory subsystems.

This role is on-site and based in one of the following locations: Toronto, Canada; Vancouver, Canada; Santa Clara, California; New Taipei City, Taiwan; or Pangyo, South Korea.

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:

  • Lead post-silicon validation of GDDR7 PHY and controller IP, including bring-up, debug, and full coverage closure.
  • Develop and execute validation plans based on JEDEC specs and system use cases; perform PVT testing, SI/PI margin analysis, and compliance validation.
  • Design and implement firmware tools to support link training, diagnostics, and calibration flows.
  • Build automated lab test infrastructure for data capture, regression, and stress testing using scripting (e.g., Python, Shell).
  • Collaborate with IP vendors, DRAM partners, and internal teams on training algorithms and debug strategies.
  • Partner with cross-functional teams to resolve system-level issues, support reliability validation, and enhance memory subsystem performance.

 

Experience & Qualifications:

  • Bachelor’s or Master’s in Electrical or Computer Engineering with experience in high-speed memory interface validation and embedded firmware development.
  • Strong programming skills in C/C++ for embedded platforms.
  • Experience with memory technologies such as GDDR7, GDDR6, DDR5, LPDDR5, or HBM.
  • Proficiency in scripting languages (e.g., Python, Shell Scripting) for automation and lab tooling.
  • Deep understanding of JEDEC memory interface standards and PHY-level training flows.
  • Hands-on experience with lab tools and test equipment such as oscilloscopes, BERTs, logic analyzers, and protocol decoders.
  • Proven ability to debug hardware/firmware interaction in silicon and system-level environments.
  • Experience with margining, calibration, or stress-mode validation.
  • Familiarity with reliability testing methodologies for memory interfaces.
  • Exposure to simulation or emulation-based pre-silicon validation.
  • Background working with memory vendors on compliance and feature integration.
  • Exposure to low level FW development for RISC-V.

 

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.

As this position will have direct and/or indirect 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 supporting documentation will be required and considered as a condition of employment.

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.

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.
