Founding Software Engineer
At The Flex, we believe renting a home should be as effortless as booking a ride.
Our mission is ambitious: enable anyone to live anywhere, anytime, without friction.
Powered by Base360.ai, our proprietary technology platform, we are building the operating system for modern renting—automating operations, connecting fragmented systems, and creating seamless experiences for guests, landlords, and operators across the world.
We're looking for a Founding Software Engineer to help architect and build the technology that powers the future of The Flex.
This is not a typical engineering role.
You'll work directly with the founder, influence product strategy, make architectural decisions, and build systems that become the foundation of a global business.
You'll have extraordinary ownership, responsibility, and impact from day one.
What You'll Build
As a Founding Software Engineer, you'll help create and scale Base360.ai—the technology platform that powers every aspect of The Flex.
From AI-powered workflows and booking systems to operational automation and intelligent decision-making, you'll build products that directly impact revenue, efficiency, and customer experience.
You won't just ship features.
You'll create systems that replace manual work, unlock scale, and become a competitive advantage for the company.
Your Mission
Build Core Products
Design, build, and launch the software that powers bookings, pricing, payments, operations, communications, and guest experiences.
Architect the Platform
Make key technical decisions and help define the long-term architecture of Base360.ai.
Create Automation at Scale
