Descrição da oferta de emprego

Role and Responsibilities

• Architecture & Hands-on Development: Technical design and delivery of new features across the TypeScript codebase (React/Next.js and Node.js).
• Core 3D Configurator: Architecting a high-performance web scene (Three.js/Babylon.js) to load, display, and interact with models for non-technical users and support higher-precision editing such as decals, placement, and transforms for experienced users.
• Sticker: Implementing feature where users are able to drop, rotate, reposition, and scale stickers/images seamlessly across curved model surfaces.
• Real-time Texture Painting (Pen & Brush): Creating a "Pen & Brush" tool that allows users to freehand draw directly onto the 3D garment and dynamic UV mapping.
• Text Manipulation Tools: Building a feature to generate dynamic text (with custom fonts and styling), rasterize it, and project it onto the models as a texture layer.
• UV Mapping Logic: Handling complex UV wrapping issues to ensure textures, drawings, and patterns wrap around seams and folds naturally without distortion.
• Asset Ingestion: Build robust logic to support the ingestion of GLB and FBX assets with embedded textures.

Essential Qualifications

• 3D Web Libraries: Extensive commercial experience with Three.js, React Three Fiber (R3F), or Babylon.js.
• Graphics Math & Geometry: Solid understanding of Linear Algebra (Vectors, Matrices) and Raycasting logic required for the "Sticker", "Material" and "Painting" tools.
• Strong professional experience with Firebase (Firestore, Cloud Functions, Authentication, Hosting, and Storage).
• Understanding of web application architecture, REST APIs, and client–server communication.
• Experience with version control systems (Git) and collaborative development workflows.
• Excellent communication skills and ability to work collaboratively in a team environment.
