About Moon 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 You will be the technical lead of Moon's core platform: auth and identity, multi-entity tenancy, the entitlements engine, payments and financing APIs, cross-platform communication services, and the databases everything runs on. Every module team builds on the foundation you keep solid. About the role
