Software Engineer (React Three Fiber)

About the role

As a Software Engineer on the 3D Systems team , you’ll be part of the core group developing a cutting-edge 3D configurator platform used across multiple industries — from cabinetry to roofing and flooring. Reporting to the Lead Software Engineer, you’ll help build and refine interactive 3D environments that simulate real-world materials, measurements, and physics. This is an exceptional opportunity to work hands-on with emerging rendering technologies, deepen your expertise in 3D web development, and contribute to a high-performance platform that must balance visual fidelity with real-time speed. You’ll work in close collaboration with senior engineers and designers to implement core features, improve performance, and support scalability.

What you'll do

• Develop, test, and optimize core modules of the 3D configurator using Three.js , React Three Fiber , and supporting technologies.
• Implement object behaviors, relational logic, and interaction systems that simulate realistic physical and spatial constraints.
• Support the creation of performant rendering and geometry handling pipelines for web-based environments.
• Collaborate with design and product teams to bring 3D visualization concepts to life in a responsive, interactive experience.
• Contribute to documentation, testing, and best practices to ensure maintainable and high-quality code.
• Assist in integrating and optimizing third-party tools such as rendering servers, Unreal Engine , or LiDAR inputs .
• Participate in regular performance audits, debugging sessions, and continuous optimization efforts.

Qualifications

• 2–5 years of professional software engineering experience, with hands-on exposure to 3D visualization or real-time rendering .
• Solid proficiency with JavaScript/TypeScript , React , and Three.js (React Three Fiber experience a plus).
• Strong grasp of geometry , vector math , and basic physics principles relevant to 3D systems.
• Experience with performance optimization, debugging rendering bottlenecks, and profiling browser-based 3D applications.
• Familiarity with WebGL , shader programming , or GPU acceleration .
• Interest or experience in LiDAR , 3D reconstruction , or virtual configurator technology .
• Eager to learn, collaborate, and grow under the guidance of senior engineers and the lead architect.
