Tech Lead / Solution Architect (Web3D)

Tech Lead / Solution Architect

Web 3D Bathroom Configurator

Role Summary

Own the architecture and technical direction of a web-based 3D bathroom configurator. Drive end-to-end decisions across frontend, 3D rendering pipeline, asset management, and backend services. One of the first key technical hires - you will define the stack, establish standards, and make the foundational decisions that the rest of the team builds on. This includes an open architectural decision: choose between React Three Fiber (Three.js) and Babylon.js based on project requirements, team composition, and long-term maintainability.

Key Responsibilities

• Evaluate and decide the 3D rendering stack: React Three Fiber (Three.js) vs. Babylon.js, with clear rationale
• Design end-to-end architecture: React SPA frontend, FastAPI/Python backend, asset pipeline
• Define data models, material/finish registry, product descriptor schemas, and API contracts
• Own the 3D pipeline: GLB conventions, material slot naming, finish system, postprocess stack
• Establish the WebGPU adoption strategy vs. WebGL fallback path
• Design integration layer for external SKU/product data sources (database connector of unknown stack)
• Establish coding standards, review critical PRs, and set the quality bar
• Lead decisions on rendering performance, asset streaming, caching, and offline mode
• Mentor engineers and unblock complex technical problems

Stack Context

The following is the current intended stack. The Tech Lead is expected to validate, challenge, or confirm these choices.

• Frontend: React · Three.js or Babylon.js (TBD) · WebGL / WebGPU roadmap
• Backend: Python · FastAPI · SQLAlchemy · PostgreSQL
• 3D Assets: GLB + material JSON registry
• External data: SKU/product DB connector (stack TBD - must support unknown source)
• Persistence: IndexedDB for client-side project state

Must-Have

• 6+ years in web architecture, including complex SPAs
• Deep experience with WebGL - Three.js and/or Babylon.js
• GLSL / shader fundamentals and GPU performance profiling
• Experience designing scalable APIs, data models, and integration layers
• Ability to make and justify stack decisions with trade-off analysis
• Experience with product configurators or real-time visualisation tools

Strong Plus

• WebGPU / WGSL hands-on experience
• @react-three/postprocessing or Babylon.js post-process stack
• GLB / glTF pipeline: asset optimisation, PBR materials, texture compression
• Python backend skills (FastAPI or equivalent)
• PWA / offline-first architecture
• Database integration across heterogeneous sources (connectors, adapters)
