Remote Web Developer Digital Twin Platform

Top 3 Reasons To Join Us The Job

About the role 

We are seeking an experienced Web Developer — Digital Twin Platform to join our team on a freelance contract basis.
This position is being advertised through our recruitment partner in Vietnam. The successful candidate will provide services to a Singapore-based technology company and will work closely with our regional team on project delivery and client engagements.

You will be expected to take ownership of core editor capabilities: 2D/3D views, semantic graph interactions, performance-sensitive visualization, and data-heavy workflows.

This is not a marketing website role; it is a deeply technical web application. 

What you will work on 

You will contribute directly to the core of or product development including: 

• A React + TypeScript application that serves as the main authoring interface 
• A Three.js–based 3D engine used for spatial visualization, navigation, and editing 
• Data-intensive UI flows for: 
  • Asset creation and editing 
  • Semantic relationships (upstream / downstream graphs) 
  • Tagging, filtering, and class management 
  • Project-scale operations (import, export, duplication, versioning) 
• Performance-critical rendering and interaction patterns across large building models 
• Tight coupling between semantic data (Brick / RDF-like graphs) and spatial representations (2D/3D) 

Key responsibilities 

• Design and implement complex React + TypeScript interfaces for a professional-grade editor 
• Build and maintain interactive 2D and 3D views using Three.js, with a strong focus on performance and usability 
• Implement editor workflows such as drag-and-drop, visual linking, inspectors, trees, and graph-like interactions 
• Work with large, structured datasets (assets, relationships, tags, classes, locations) backed by SQL 
• Ensure consistency between semantic models and visual representations 
• Collaborate on data ingestion and export pipelines (CSV, JSON, IFC, semantic formats) 
• Participate in architectural decisions around state management, data flow, and rendering strategies 
• Write clean, maintainable, and well-typed code that can evolve with a long-lived product 
• Debug and optimize performance issues across rendering, data handling, and UI state

Your Skills and Experience

Required technical skills 

You should be very solid in the following areas: 

• TypeScript — strong typing discipline, not just “JS with types” 
• React — building complex, state-heavy applications 
• Three.js — this is critical 

You should be comfortable with scenes, cameras, controls, geometries, instancing, picking, transforms, and performance trade-offs 

• SQL — strong understanding of relational data modeling, querying, and data integrity 
• Rust — used for performance-sensitive logic, tooling, or backend-adjacent components 

You should also have basic but real familiarity with: 

• AWS — understanding how web applications are deployed and operated in the cloud 
• Kubernetes — you don’t need to be an expert; the platform and workflows can be taught (as has been done successfully before) 

Nice to have (but not required) 

• Experience with graph-like data structures or knowledge graphs 
• Background in GIS, BIM, IFC Digital Twins, or Civil / infrastructure software 
• Experience optimizing large-scale Three.js scenes 
• Familiarity with RDF, ontologies, or semantic modeling concepts 
• Familiarity with Brick Schema 
• Familiarity with OpenBIM, IFC.
