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

IdelSoft

United States
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.

Key Responsibilities
  • Build and maintain responsive, high-performance frontend applications using Svelte.
  • Develop interactive and real-time experiences using Three.js and/or Unity (C#).
  • Design, implement, and maintain backend services, APIs, and database schemas.
  • Work with Supabase to manage data, authentication, and real-time subscriptions.
  • Deploy and manage applications using Cloudflare (Workers, Pages) and Vercel.
  • Participate in the full development lifecycle: planning, architecture, implementation, and deployment.
  • Write clean, maintainable, and well-tested code following best practices.
  • 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
  • 4+ years of professional software development experience.
  • Strong proficiency in modern frontend development (Svelte preferred or willingness to adopt it fully).
  • Experience with real-time 3D rendering using Three.js, Unity, or similar technologies.
  • 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).
  • Strong understanding of frontend architecture, state management, and performance optimization.
  • Ability to work across the full stack with a product-oriented mindset.
  • Excellent communication skills and ability to clearly explain technical decisions.
Why Join Us
  • Work in a small, high-impact team where your contributions directly shape the product.
  • Own features end to end and influence architectural decisions.
  • Build cutting-edge real-time and 3D web experiences.
  • Flexible remote environment with fast iteration and minimal bureaucracy.

Tech Stack: Svelte (frontend), Three.js & Unity C# (real-time/3D), Node.js (backend services & APIs), Supabase (PostgreSQL, auth, real-time), Cloudflare (edge infrastructure), Vercel (frontend deployment & CI/CD)

Benefits
  • 100% remote
  • Competitive salary in USD
  • PTO (vacation, sick leave, holidays)
  • International experience
  • Udemy trainings covered
  • $200 for home-office equipment
