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.
