Job description

Untether AI has built the world’s highest-performance, energy-efficient AI inference accelerator. We are a Toronto-based startup with employees across Canada and the US (and even a few outside North America), and we are rapidly growing to scale out our second-generation product while developing our third.

We are searching for an engineering expert on silicon characterization to help us define the production operating points of our silicon. You will design experiments, analyze data and make recommendations on how to bin our chips to optimize the performance, power, and yield

Responsibilities:

Own all technical aspects of chip binning from design of experiments to data analysis
Collaborate with the Product Team to set preliminary and final product definitions
Set requirements for the Validation Team to create appropriate tests
Work with the Product and Test Team to correlate results with ATE
Participate in chip design as necessary to ensure we deliver the best product

The ideal candidate will possess the following skills, and experience:

7+ years of experience binning large chips (CPUs, GPUs, SOCs, NICs, etc)
Ability to define and run experiments and analyze the data
Deep understanding of silicon variation across process, frequency, temperature
Experience with yield recovery, repair, floor sweeping, or similar
Clear vision for how to organize and present vast quantities of data
Excellent communication and presentation skills
Track record of cross-functional collaboration with technical and non-technical teams

What are some of the perks that you will receive being part of Untether AI? Aligned to Untether’s philosophy, our employees enjoy the same perks, regardless of role or level. In part, these include:

20 vacation days
Strong health and extended health benefits
Unlimited sick days
Stock options
Building hardware and software that will change the world

Thinking about applying?

We’re a pretty welcoming bunch of people. If we’ve piqued your interest, you’re passionate about the same things we are but you aren’t sure if you check all the boxes, please apply anyway. We’re a great place to work, an even better place to learn and we focus on both capability and potential!

Besides being a pretty friendly group, we’re also pretty diverse - ethnically, experientially and in our physical and mental abilities. If you are someone who needs accommodation during the interview process and/or in the workplace, please send a note along with your resume to [email protected] and we’ll be in touch.

A little bit more about Untether AI

Untether AI has developed a groundbreaking new architecture that brings neural net inference to new levels of performance and efficiency. We’ve already sold our product to smart clients who want to get in at ground zero. We’ve done this while continuing to improve our technology creating ultra-efficient, high performance AI chips that eliminates the data movement bottleneck that costs energy and performance in traditional architectures. We’re a team made up of scientists, engineers and entrepreneurs and have the support of tier one investors. Join us to be part of something big - a chance to create the future of AI.
