Senior Three.js Developer

Our client is on a mission to transform how people experience and interact with the built environment. They're building a next-generation AEC platform that combines advanced 3D rendering, LiDAR, and AI and they need a founding engineer to bring it to life.

This is your chance to build something meaningful from the ground up: the architecture, the product, and the engineering culture. If you're looking for ownership, autonomy, and impact this is it.

What You'll Be Building

As one of the first engineers on the team, you'll shape the technical foundation of the entire platform:

• Architect and build a performant, scalable 3D engine for digital inspections and spatial analysis.
• Solve technically demanding challenges like real-time visualisation of large LiDAR datasets, procedural geometry rendering with Three.js, and integration with AI models.
• Work across the full stack frontend (React, TypeScript), backend (Rust or C++), and cloud infrastructure (e.g. GCP or AWS).
• Collaborate closely with the founders to define the roadmap, refine the product, and make critical technical decisions.
• Set engineering best practices and foster a strong culture of code quality, innovation, and curiosity.

What They're Looking For

They're not hiring just a developer they want a builder with a product mindset. Someone who thrives in early-stage business and enjoys turning complex ideas into working software.

Must-Haves

• 5-10 years of experience in software engineering, ideally across both frontend and backend.
• Solid knowledge of JavaScript/TypeScript, with experience in React and Three.js.
• Hands-on experience with cloud platforms (GCP, AWS, or Azure).
• Comfortable navigating ambiguity and building without a blueprint.

Nice-to-Haves

• Experience with C++, Rust, or other systems-level languages.
• Background in OpenGL, WebGL, or real-time 3D graphics.
• Familiarity with LiDAR, point clouds, or spatial/geometric datasets.

Mindset & Culture Fit

• You're a problem-solver at heart you don't just code, you think deeply about why something should be built.
• You care about long-term maintainability as much as shipping fast.
• You challenge assumptions, push boundaries, and bring creative solutions to the table.
• You thrive in fast-moving, collaborative environments with a clear mission.

This isn't just another engineering role. Its a founding opportunity to shape a revolutionary platform with real-world impact in the AEC industry. If you're excited by that, we'd love to hear from you.
