Lead Full-Stack Engineer

Lead Full-Stack Engineer Join the team redefining the future of global living. At The Flex, we believe renting a home should feel instant, intelligent, and effortless — as seamless as booking a ride. Our ambition is bold: enabling anyone to live anywhere, anytime, without friction. Powered by Base360.ai, our proprietary automation engine, we’re building the operating system for modern renting — connecting property data, orchestrating operations, and enabling seamless stays across continents. If you’re driven by technical ownership, system architecture, and building platforms that operate at real-world scale, this role puts you at the center of how millions of people move, live, and experience the world. What You’ll Build As a Lead Full-Stack Engineer, you will own the architecture and technical direction of The Flex platform — spanning web applications, APIs, automation engines, and cloud infrastructure. You’ll lead by building. You’ll design systems, set standards, and make key technical decisions while remaining deeply hands-on across the stack. This is not a people-management role. It’s a technical leadership role for someone who wants to shape systems, mentor by example, and build platforms that scale globally.
