Front-End Engineer - 3D Visualisation & Intelligent Construction Platform (WebGL)

About the Opportunity

We are partnering with an innovative technology company developing a next-generation platform that combines artificial intelligence, construction data, and digital building models to help project teams make faster, more informed decisions.

The platform brings together BIM models, technical drawings, schedules, specifications, cost data, and site information into a single intelligent environment. The goal is to transform fragmented project information into actionable insights that improve project delivery across the built environment.

As a Front-End Engineer, you will play a critical role in building the user experience layer of the platform. You'll develop advanced 3D visualization tools, AI-powered workflows, and high-performance web applications capable of handling large-scale construction datasets.

What You'll Be Doing

Advanced 3D & BIM Visualisation

Develop browser-based 3D viewers capable of handling large BIM and digital construction models.

Implement functionality such as model navigation, element selection, isolation, sectioning, filtering, and property inspection.

Optimise rendering performance for large datasets through techniques such as:

• Level of Detail (LOD)
• Geometry streaming
• Lazy loading
• Frustum culling

Model segmentation and tiling

Support multiple construction data formats including BIM models, CAD drawings, PDFs, and future integrations such as point clouds and reality capture data.

Ensure smooth performance even when working with complex projects containing hundreds of thousands of model elements.

AI-Powered User Experiences

Build interfaces that allow users to interact naturally with AI assistants and automation workflows.

Create responsive experiences for real-time AI interactions, including streamed responses and live updates.

Design review and approval workflows where human expertise remains central to decision-making.

Develop intuitive visualisations that help users understand:

• Project risks
• Model clashes
• Cost impacts
• Schedule implications
• Compliance findings

Ensure every insight can be traced back to its original source data for transparency and trust.

Front-End Architecture & Engineering

Define and maintain scalable front-end architecture standards.

Build reusable component libraries and establish engineering best practices.

Integrate with REST APIs and real-time communication services.

Collaborate closely with product designers, AI engineers, and backend developers.

Drive performance improvements across the application.

Create automated tests for critical user workflows and interactive components.

Take ownership of features from concept through production deployment.
