Summary Freelance 3D Engineer (Three.js / WebGL / React Native) 1)The project We're building a 3D experience for a health/medical social impact product (mobile first). The main model, animator, and rigger are already in place. We need a specialist to set up the shaders and cube maps, and help establish the 3D environment. 2) What you'll be doing - Setting up PBR shaders for a range of materials: metal, glass, ceramic, plastic, paper, fur - Creating cube maps and configuring environment mapping - Helping initiate the 3D scene and building the first few cube maps to a production-ready standard 3) Stack Three.js, WebGL, React Native, Blender 4) Ideal background The most important thing is a strong foundation in at least one of: 3D graphics, shaders, lighting, or real-time rendering. Beyond that, we prioritise in this order: - Mobile-first experience — the product is mobile, not PC or console. Experience building or optimising real-time 3D on mobile is essential. - React Native and/or WebGL — hands-on experience with our stack is a strong plus. - Three.js — ideal, but transferable WebGL experience is fine (this is not a Unity project). - Comfortable with PBR shaders and real-time environment mapping. - Blender experience is a plus. 5) Engagement - Initial contract: 2–4 weeks - Ongoing maintenance: ~1–2 days per month after that - Flexible hours - A senior engineer (20 years experience) is available for guidance 6) Nice to know This is a social impact project in the health/medical space. We're a small, focused team and collaboration is straightforward. 7) To apply Please apply via the platform and include examples of relevant 3D/shader work.
