Simple Ventures | Toronto, Canada | ONSITE (3-4 days/wk) | Full-time

Simple Ventures is a Canadian venture studio that builds new companies from day zero - we source ideas, validate them with real users, build MVPs, and hand off to CEOs to scale the ones we bet on. We're backed by the founders and leaders of Wealthsimple, Shopify, Ada, MindBeacon, and TD.

We're hiring for two roles:

Founding AI Engineer - the technical backbone of the studio. You'll build internal tooling, prototype MVPs for new ventures, and partner with our portfolio companies on applied AI.

New Venture Lead (0→1) - you'll operate like a founder, sourcing venture ideas, running validation loops with real users, killing weak ideas quickly, and writing CEO-ready memos for the ones we decide to invest in.

Acrylic Robotics | ML Lead | Montreal, QC | Onsite/Hybrid | Full-time

Acrylic Robotics is a creative tech company focused on changing how people design and create art. We build software that learns a person's taste in art, ML design tools that turn it into a concept, and robots that create the concept with paint on canvas, so original artwork can be commissioned at a price most people can actually afford.

We're hiring an ML lead to own the model side. The system has to take a user's intent and references, turn them into concepts the user can refine through feedback, and produce the brushwork-level instructions our robots paint. This would be the first dedicated ML hire on the team; they'll help set the technical direction, ship the first real end-to-end version, and build out the team behind them.

We're based in Montreal, QC, but open to a hybrid position for the right person. Please email me at walker@acrylicrobotics.ca or look at https://acrylicrobotics.ca for more info.
