Three.js developer - Advanced 3D Web Application

We are looking for a developer with strong 3D web fundamentals and the grit to dive into an existing codebase, refactor thoughtfully, and ship high-quality features.

What you’ll work on:

• Implementing and optimizing complex 3D interactions in the browser - custom geometries, shapes, raycasting, post effects
• Evolving an existing architecture - introducing clear command patterns, improving state flows, and reducing tech debt
• Floorplan logic and constraints - graph-based modeling, snapping, validation, and measurements

• Collaborating closely with designers and 3D engineers to align performance, UX, and rendering quality

   

Must-have qualifications:

• Engineering background or equivalent hands-on experience
• Solid math for real-time graphics - matrices, quaternions, vector math
• Basic graph theory - practical use for floorplan construction and constraints
• Strong experience with Three.js - custom geometries, shapes, raycasting, post-processing
• Experience with preact/signals or a similar signals-based pattern for state
• Familiarity with the command pattern and undo-redo architecture
• Working understanding of React (v19 readiness is a plus)

• Proficiency with TypeScript

   

Nice to have:

• Experience with Konva.js for 2D canvas overlays and editors
• Familiarity with performance profiling and WebGL performance budgeting
• Comfort working with scene graphs, asset pipelines, and geometry utilities

• Prior work refactoring medium-large front-end codebases

   

Soft skills that matter:

• High attention to detail and perseverance - there is existing code to understand, refactor, or rewrite where needed

• Structured thinking, clean abstractions, clear communication

   

What to include:

• CV and a link to your active GitHub profile

• Short note with relevant 3D or complex UI examples - links, demos, or repos are great

   

If this sounds like you, reach out - we’d love to talk.
