Engineering Manager, 3D Platform

About the role

Moon is an ambitious, independent vertical SaaS company incubated by Home Organizers, a market leader with decades of proven success in home organization through its subsidiaries, including Closet World, Closets by Design, and Brio Water Technology. Born inside one of the industry's largest operators — 6,000+ employees, hundreds of thousands of new customers served annually — Moon is built on a rare advantage: we build for the home improvement industry from within it. Our mission is to reinvent the home improvement experience end to end. From AI-driven marketing and in-home 3D design to sales, service, and operations, Moon unifies the entire customer and business journey on a single platform — supercharged by Luna, our proprietary AI engine. Where most operators stitch together disconnected tools that don't understand the homeowner, we're building the unified operating system the industry has never had. We're a rapidly growing team of committed builders, driven to reimagine how this industry sells, designs, and delivers — and to power the next generation of operators, from single-location dealers to national franchise networks. Role Overview: We are looking for an Engineering Manager, 3D Platform to lead the development and evolution of Moon's real-time 3D design platform. This is a highly technical, hands-on leadership role for someone with deep experience building browser-based 3D applications, parametric design systems, and high-performance graphics experiences. Our 3D platform is used by designers in customers' homes to configure and visualize highly customizable products in real time. The experience must translate complex product rules, dimensions, components, and constraints into an intuitive design environment that performs reliably on tablets. You will own the architecture and technical direction of this platform while building and leading the engineering team responsible for it. We are looking for a player-coach who can establish architectural standards, develop engineers, review complex technical decisions, and still get into the code when needed.

Responsibilities

• Build, hire, mentor, and lead a high-performing engineering team dedicated to Moon's 3D platform.
• Own the architecture, technical strategy, and engineering roadmap for our real-time 3D design and configuration environment.
• Lead the development of parametric product configuration capabilities, enabling complex products to be dynamically generated and modified based on dimensions, constraints, rules, and component relationships.
• Drive development of sophisticated 3D environment and spatial design tools, including CAD-like functionality for creating, manipulating, measuring, positioning, and configuring products within a room or design space.
• Own rendering architecture and performance across Three.js, React Three Fiber, WebGL, and emerging WebGPU technologies.
• Establish and maintain strict library and API boundaries, ensuring the 3D platform remains modular, scalable, maintainable, and easy for other engineering teams to build upon.
• Optimize real-time 3D performance for tablet environments, including rendering performance, memory utilization, responsiveness, and reliability in real-world customer environments.
• Work closely with Product and Design to translate complex product and design requirements into intuitive
