Our take

Plaud is tackling one of the most fascinating design challenges in AI hardware — making voice recording feel natural and trustworthy rather than creepy or invasive. This HCI role sits at the intersection of physical product design, AI interaction patterns, and the delicate psychology of how people share their conversations with machines. Perfect for a designer who gets excited about creating entirely new interaction paradigms and wants to shape how we'll naturally communicate with AI in the physical world.

    Plaud is a rare bootstrapped hardware+AI success story hitting $250M revenue run rate in 3 years.
