Founding Fullstack Engineer

Matchii is the new way to hire agencies: matched, not browsed. Hiring an agency today is a slog: 20+ quotes, 40+ hours of vetting, and a gut-feel pick that's wrong about half the time. Matchii makes it feel like booking the perfect flight; describe what you need, the right team appears, work begins. Human, AI-native, or hybrid. We match. We back the outcome. Behind the scenes, it's two products on one platform: a matched marketplace for the people doing the hiring and an operating system that the agencies run their whole business on. Underneath both is a data layer, the largest dataset of real services pricing and outcomes anywhere, that makes every match smarter than the last. The timing is the whole point. The $500B+ global agency services market is old and broken, and AI just blew the supply side open: 100+ AI-native services launched in the past year alone, with no platform connecting buyers to the new shape of supply. That gap has been open for years. We're building the company that fills it. Role summary Fullstack Engineers at Matchii build the products, systems, and experiences that power our platform.
