What are the responsibilities and job description for the Senior Software Engineer (React Three Fiber) position at Moon?
About Moon
An ambitious and independent stealth SaaS company incubated by Home Organizers, a market leader with decades of proven success in designing and delivering exceptional, innovative home organization solutions through its subsidiaries Closet World, Closets by Design, Brio Water Technology, and others. Backed by their deep industry experience and a commitment to be Home Organizer’s critical SaaS provider for its 6000 employees, our team is building innovative solutions to solve universal problems that most businesses face — yet are not addressed by a single, unified tool.
Our mission is to transform the entrepreneurial experience and deliver operational excellence for businesses across the world through a unified platform supercharged with proprietary AI agents. We want to unleash the creativity of billions and inspire the world to dream big and build fast. We’re a rapidly growing team of forward-thinking and, most importantly, committed builders. We are driven by the opportunity to push boundaries, reimagine the foundations of human work, and shape tools that power the next generation of “business operations.” The way the world views and does business is changing, and we are committed to leading this change responsibly.
About The Role
As a Senior Software Engineer on the 3D Systems team, you’ll work alongside our Lead Engineer to develop a high-performance, real-time 3D configurator that redefines how users design and visualize physical products such as cabinetry, roofing, flooring, and tiling. You’ll be deeply involved in architecting, building, and optimizing our proprietary 3D engine that bridges the virtual and physical world. This role requires exceptional technical skill in spatial reasoning, rendering pipelines, and interactive visualization — as well as a passion for solving complex real-world geometry and physics problems through elegant code. You’ll play a key role in implementing scalable features, improving system performance, and ensuring that our configurator remains the fastest and most accurate in the industry.

What You'll Do
- Work closely with the Lead Software Engineer to design, build, and refine components of the proprietary 3D configurator using Three.js, React Three Fiber, and WebGL.
- Implement advanced spatial logic, physics-based interactions, and material simulation between virtualized and real-world objects.
- Develop and optimize shaders, rendering pipelines, and geometry processing systems for maximum visual fidelity and performance.
- Collaborate cross-functionally with design and product teams to translate architectural and construction requirements into interactive, data-driven simulations.
- Contribute to architectural decisions related to scalability, modularity, and multi-industry adaptability (cabinetry, flooring, roofing, etc.).
- Assist in integrating external technologies including Unreal Engine, Unity, LiDAR, and 3D scanning inputs to expand configurator capabilities.
- Drive continuous improvement in code quality, performance benchmarks, and development practices across the engineering team.
- 5–8 years of professional software engineering experience, including at least 3 years building 3D or simulation-based systems.
- Strong experience with Three.js, React Three Fiber, and WebGL, plus familiarity with TypeScript, Node.js, and modern frontend frameworks.
- Advanced understanding of geometry, vector math, physics simulation, and spatial reasoning.
- Proven experience optimizing rendering performance and implementing GPU-based computations or shaders.
- Familiarity with Unreal Engine, Unity, or other 3D rendering environments.
- Experience working with microservices, APIs, and scalable systems architecture.
- Bonus: Exposure to LiDAR, photogrammetry, or 3D asset processing pipelines.
- Strong collaboration skills and a detail-oriented mindset — able to bridge product requirements with technical execution.
