Full-Stack (Svelte, Three.js & Unity C#) - LatAm

We are looking for a versatile and technically strong Full-Stack Engineer who can design, build, and ship high-quality applications across frontend, backend, and real-time interactive environments. You will own features end to end — from UI implementation and 3D experiences to backend logic and cloud deployment — in a fast-moving, high-trust team where your decisions have direct impact.

The focus of this role is building modern, real-time, and interactive web experiences, combining clean frontend architecture with immersive 3D capabilities and scalable backend systems. This is a hands-on role with strong ownership and influence over technical direction and product quality.
