Founding Game Designer at PebbleVC-backed generative AI startup

Join Pebble as a Founding Game Designer to build the world’s first generative learning environment for kids. Led by former Google and Synthesia leaders, we're creating a voice-driven, procedural 2D world where AI companions help children learn and play. If you're a systems thinker who wants to move beyond scripted levels and define a new category of AI-native gaming, this is your chance to join a high-growth startup at the ground floor with significant equity and impact.
