At The Flex, we believe renting a home should be as effortless as booking a ride.

Our mission is to 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 Full-Stack Engineering Lead to help scale both our technology and our engineering culture.

This is a hands-on leadership role. You'll spend the majority of your time building products, solving technical challenges, and architecting systems while also helping guide engineering standards, mentoring team members, and shaping the future of the platform.

If you're excited about ownership, rapid execution, AI, automation, and building products that have real-world impact, we'd love to meet you.

You'll work across product, engineering, AI, and operations to create scalable systems that automate processes, improve decision-making, and accelerate company growth.

You'll be responsible not only for what gets built, but how it's built.
