Lead Software Engineer (Reach Three Fiber)

Location: Glendale, CA

Department: Engineering

Role Overview

We are seeking a Lead Software Engineer to architect and build an advanced, propietary 3D configurator platform that revolutionizes customization experiences in the in-home services particularly cabinets, roofing, tiling, flooring, and other industries. This role combines deep technical expertise in 3D rendering, spatial computation, and interactive visualization with strong leadership in software architecture and optimization. The engineer will be responsible for designing and implementing performant, real-time configurator experiences that simulate complex physical environments while maintaining speed, accuracy, and scalability. Daily work will involve leading development efforts using Three.js, React Three Fiber, and related 3D web technologies, collaborating closely with designers and engineers to define interaction logic, rendering pipelines, and system architecture. The successful candidate will set new benchmarks in virtual product configuration performance and realism.

About the role

As the Lead Software Engineer for 3D Systems, you’ll join a high-impact team focused on building a proprietary, next-generation configurator that bridges the virtual and physical world. You’ll collaborate with a multidisciplinary group of developers, UX designers, and product engineers to create seamless, visually rich configurators capable of simulating real-world physics, spatial relationships, and materials. This is a highly technical and creative role, requiring an understanding of rendering engines, 3D geometry, and optimization for real-time environments. You will influence both technical strategy and architectural direction, ensuring that the configurator framework is adaptable for multiple verticals — from cabinetry to roofing and beyond.

What you'll do

• Architect and lead the development of a high-performance 3D configurator system built on Three.js and React Three Fiber, optimized for web and native mobile platforms. As well as make key decision on libraries, applications, interfaces, and languages to utilize.
• Design and implement complex spatial reasoning logic, physics simulations, and relational constraints between virtual objects.
• Collaborate with designers and product leads to translate real-world material, physics, and measurement properties into virtual configurations.
• Integrate rendering technologies and explore interoperability with engines such as Unreal Engine or Unity, as well as LiDAR and 3D scanning inputs.
• Optimize the system for real-time interactivity, achieving sub-second rendering and fluid transformations for complex geometries.
• Establish code quality standards, performance benchmarks, and best practices for 3D web application development.
• Mentor and guide a team of engineers in best practices for modern 3D systems architecture, graphics optimization, and mathematical modeling.
• Create a scalable and proprietary system for object definition that will allow for multi-industry scaling with one unified 3d engine.

Qualifications

• 8+ years of professional software engineering experience, with 5+ years focused on 3D visualization or interactive simulation development.
• Deep expertise in Three.js, React Three Fiber, WebGL, and TypeScript/JavaScript.
• Strong foundation in mathematics, physics, and spatial reasoning, especially geometry, linear algebra, and vector transformations.
• Proven experience optimizing real-time rendering performance and working with shader programming or GPU-based computation.
• Familiarity with Unreal Engine, Unity, or other 3D rendering servers.
• Experience developing for multi-vertical applications (e.g., manufacturing, design, construction, or architecture tech).
• Bonus: Exposure to LiDAR, photogrammetry, or 3D reconstruction technologies.
• Excellent communication, problem-solving, and leadership skills — capable of translating complex technical concepts into scalable solutions.
• Experience working in microservices architecture and developing enterprise applications with reliability and 99.99% uptime.
