We’re partnering with an innovative mobile game studio building a next‑generation 3D experience that blends engaging gameplay with meaningful learning. They’re entering a major growth phase and are looking for a Senior Unity Developer to help shape the technical foundation of a product designed to reach families at scale.

This is a hands‑on, high‑impact role.

Experience with F2P systems, subscriptions, analytics tools, or kids/family products is a strong plus.

This is an opportunity to step into real ownership and help build something that combines strong gameplay with real‑world impact.
