Untether AI is building the world’s highest performance pure-digital AI inference chip.  We’re a rapidly growing Toronto-based startup, with employees across Canada and the US, building next generation hardware AI accelerators for neural net inference.  We are investing in software in a big way in order to make it as seamless as possible for researchers and developers to successfully deploy neural networks on our hardware. 

We’re looking for best in class engineers  to join our existing top-notch team.  When you join Untether AI, you will be part of the team that creates innovative hardware and delivers industry leading AI performance and efficiency. Utilizing non Von Neumann techniques, you will help propel sustainable AI inference.
As part of this talented team of engineers, you are able to - and are excited to - architect, implement, verify and productize custom hardware designs.  Being on our team means collaborating with an extremely bright group of people while tackling tough and interesting problems at the intersection of AI and hardware.

We are looking for a Senior Integrated Circuit Design Engineer.  The desired candidate would have previous exposure to RTL design and logic synthesis,  clocking and timing convergence,  transistor level circuit design,  and FinFET layout implementation.   Experience taking multiple products through design, verification, and product test is also highly desired.


    • Collaborate with Microarchitects, Software Engineers, Logic Engineers, and other Circuit Design Engineers to determine circuit design requirements
    • Develop and generate schematics for custom circuit designs that meet project requirements
    • Oversee physical layout implementation of circuit designs
    • Verify timing, power, functional, and yield performance of circuit designs
    • Lead group design efforts and mentor other engineers


    • Bachelor's or Master’s in Electrical Engineering, Computer Engineering or Computer Science
    • Circuit design, Circuit Layout, and VLSI Design
    • Spice simulations, transistor's type, and usage
    • Static Timing Analysis experience
    • Linux or Unix
    • Candidates must be located within North America, preferably in Toronto

Preferred Skills & Experience

    • Exposure to layout and/or schematic entry using Cadence Virtuoso and/or Synopsys Custom Compiler
    • Exposure to FinFET Technology
    • Clock distribution and full chip clocking methods
    • Exposure to Layout Place and Route implementation
    • Exposure to Verilog RTL Development

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 chips 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 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. We recently received $125 million in our series B funding round which enables us to expand our customer engagements, enhance our software offering, and build the next generation of industry leading AI inference products. Join us to be part of something big - a chance to create the future of AI.
