At playgeni, we’re inventing the future of play. Our mission is to build physical products that bring artificial intelligence and generative storytelling to the hands of every child in the world. We are a small team of creatives and engineers from MIT and Harvard who believe play should spark curiosity and drive learning. 

We are building an interactive toy that lets kids mix and match blocks to create unique audio stories based on their choices. Blocks come in themed books, so each collection opens up a whole world of story possibilities.

We are launching our first product this year, and we are hiring our first designer. 

You will own design across the company:, our website, mobile app, packaging, brand presence in ads and social, and physical touchpoints where families meet playgeni. You will work directly with the founders, ship fast, and see your work in the hands of thousands of families within months. This role rewards people who take initiative and make decisions with incomplete information and ambiguity. 

We build AI products and we work like it: you will use AI tools throughout your workflow to generate options faster, automate repetitive production work, and multiply your output. You will also design with evidence. Every major decision should trace back to user feedback, playtest observations, or performance data, and you will be expected to instrument, measure, and iterate on what you ship. You will set the visual and interaction standards that every future designer and contractor at playgeni inherits. If you are a visual designer, innovator, and want to reimagine generative storytelling for young listeners, this role is for you. 

This is an in-person role based in Brooklyn, NY.
