About the role

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.

Collaborate closely with cross-functional teams to deliver scalable and user-centric solutions.

Contribute to architectural decisions and continuously improve system performance and reliability.

Key Requirements

Solid experience with backend development using Node.js.

Experience working with PostgreSQL-based systems or BaaS platforms like Supabase.

Familiarity with serverless and edge environments (Cloudflare Workers or similar).

Ability to work across the full stack with a product-oriented mindset.

Excellent communication skills and ability to clearly explain technical decisions.

Nice to Have
