Description
Pebble - Founding Game Designer ABOUT US We’re second-time founders and former Google and Synthesia leaders (Search, Voice, and Assistant). We're assembling a core team of engineers, artists and educators to build the interface between AI and childhood. THE PROBLEM WE'RE SOLVING Kids between 6 and 10 spend hours every day on screens, but most digital content is passive (TV, YouTube) or repetitive (apps, games). Parents want safe, engaging, and educationally positive experiences. Kids crave play, parents crave development and safety, and the industry hasn’t bridged that gap. OUR PRODUCT Pebble is building the first generative learning world. If you’ve read the Diamond Age https://www.amazon.co.uk/dp/0241953197/?bestFormat=true&k=the%20diamond%20age&ref_=nb_sb_ss_w_scx-ent-bk-ww_k0_1_15_de&crid=138ZSAO9S8AZV&sprefix=the%20diamond%20age, you know what that means. If you haven’t, this video https://drive.google.com/file/d/1Hk0qdkLVFUIrlUw93WIjMcYguty6VswG/view?usp=sharing will bring you up to speed. Pebble first version is a 2D exploration game built in Godot 4. Children explore a procedurally generated world alongside an AI companion character they interact with through voice. Conversations are open-ended, not scripted. The companion isn't a sidekick, it's the core relationship that drives engagement, learning and emotional investment. The design challenge is unlike traditional game design. The world is generated and the narrative is emergent. The content adapts to each child's interests and developmental needs in real time. The game designer's job isn't to build levels, it's to design the systems and constraints that make a generative world feel coherent and worth coming back to. FOUNDERS Guillaume https://www.linkedin.com/in/guillaume-bonifacechang/ (CPTO): First product hire at Synthesia, where he scaled from $3 to $100M ARR and helped define the category of AI video. Spent 7 years at Google as a PM on Search. Dad of two (ages 7 and 9), giving him a front-row seat to what captivates and educates kids today. Lio https://www.linkedin.com/in/lionelmora/ (CEO): Second-time entrepreneur: founder of Neoplants http://www.neoplants.com, raised $25M+ from top-tier US investors. Ex-Google PMM, part of the original Google Assistant EMEA launch team (2017). Creative technologist and product builder with 15 years across tech, storytelling, and consumer launches. ABOUT YOU You think of yourself as a pirate. Wait, maybe that’s too specific. A bear will do too. The point is, you want to bring something special to this world. Something wonderful. In corporate speak, we might say that we're looking for an ambitious and forward looking Game Designer who's excited at the prospect of inventing a new gaming paradigm with AI at its core. You’re comfortable thinking from first principles about what makes a great game. You understand what AI will change and what will remain the same. You've worked on 2+ games from scratch, at reputable studios or on your own. You have strong opinions about what the future of games look like. What we’re looking for, really, is someone who knows games in and out, and wants to join us to build something extraordinary for children. THE ROLE You'll be Pebble's first game designer, responsible for defining how an AI-powered world actually feels to play. That means designing the exploration systems, pacing, and progression mechanics that make kids want to come back, not through dark patterns, but through genuine curiosity and a deepening relationship with an AI companion character. You'll work at the intersection of game design, child development, and generative AI, building design frameworks from scratch in a Godot 4 environment where the content is procedural and the interactions are voice-driven. This is a unique opportunity to create a completely new kind of game experience that goes beyond entertainment. This is an opportunity to shape the future of parenting and educati
