As Lead Product Designer, you will own Pebble’s product craft end-to-end, from UX and UI to motion and visual language. You’ll design immersive 3D experiences at the intersection of gaming and AI, implementing your work directly in the codebase to create a product that balances child-like wonder with parental trust.
Lead Product Designer at Pebble
Pebble is building the world’s first generative learning environment for children, and they need a Lead Product Designer to define its soul. Founded by ex-Google and Synthesia leaders, this London-based team is creating a 3D adventure game where AI characters engage kids in open-ended, developmental conversations. You’ll own the entire design language—from UX to motion—aiming for the geometric rigour and beauty of titles like Monument Valley. If you want to move beyond passive screens to build a product category founded on trust and craftsmanship, this founding-level seat offers significant equity and the chance to leave a lasting mark on childhood education.

Role overview
The first generative world for children. As engaging than Netflix, as enriching as private lessons.
What you will do
- Lead the end-to-end design of the product, including UX, UI, visual identity, and high-fidelity motion for a 3D Unity-based adventure game.
- Collaborate directly with the founders to translate ambitious product strategies into simple, intuitive interactions that children and parents both love.
- Build and iterate on client-side code, bridging the gap between design and implementation to ensure every pixel and transition meets world-class standards.
Who this is a fit for
- Demonstrates a portfolio of shipped products with exceptional visual sensibility, mastering typography, composition, and interaction design beyond static screens.
- Possesses strong product instincts for turning ambiguous AI capabilities, such as open-ended voice interactions, into cohesive and trustworthy user experiences.
- Has technical proficiency to implement designs within a codebase, ideally with experience or interest in Unity, C#, or similar game engines.
Why this role is remarkable
- Join a founding team led by the first product hire at Synthesia (scaled to $100M ARR) and a second-time founder who raised $25M+ from top US investors.
- Define a new category of “generative learning” by designing a 3D world where AI characters provide unscripted, developmental value rather than passive consumption.
- Exercise total ownership over a high-polish visual aesthetic—aiming for “Monument Valley” levels of craft—while shaping the core product direction from the ground up.
