Lead Full-Stack Engineer

oin 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.

Architect scalable, well-structured APIs that connect Base360.ai to internal tools and external partners.

Automate the Business

Build event-driven services and intelligent workflows that replace manual operations across the company.

Integrate at Scale
