About Hapiko Hapiko is a Brooklyn-based company building the future of play.
Description Founded by Arun Gupta (former CEO of Grailed, which sold to GOAT Group in 2022) and Bob Whitney (Anthropic, NYT Games), we're on a mission to create safe, hands‑on AI experiences that fuel kids' imaginations rather than replace them.
Our first product, Stickerbox, is the world's first voice‑to‑sticker printer. A device that instantly transforms a child's spoken ideas into printable, colorable stickers. We sold out our first run shipping for the holidays, and additional batches beyond that. It's already being called "one of the first products to make AI feel magical for kids and grounded for parents."
We have a $7M funding round led by Maveron (backers of Lovevery), Serena Ventures, and Ai2 (The Allen Institute). Stickerbox is already in homes bringing imagination to life for kids nationwide!
Why are we hiring? The technical challenge is real. We're running real‑time streaming, processing thousands of concurrent connections from IoT devices, and orchestrating ML pipelines that return magical responses in seconds or less. Our hybrid Python‑Elixir architecture handles everything from device authentication to job queuing to image delivery, all with the reliability parents expect and the speed kids demand.
We need a Backend Engineer to own and evolve this infrastructure. You'll architect and maintain the systems that connect thousands of devices, manage real‑time audio pipelines, and power the experiences that make everything just work. This is a foundational role where your decisions will shape how we grow from thousands to millions of users.
