Born out of The Flex, a short-term rental operator that scaled to an eight-figure business using its own software, is now launching as a standalone platform for short-term rental operators worldwide.
We bring reservations, guest communication, pricing, payments, cleaning, maintenance, and reporting into one platform—helping operators automate manual work, reduce costs, increase revenue, and scale their portfolios.
We're looking for a highly ambitious Senior Software Engineer who wants to build systems that solve real problems at scale. You'll build, ship, automate, and deliver products that directly impact property managers, their teams, and their guests.
If you're excited by APIs, automation, AI agents, cloud infrastructure, and building products from the ground up, we want to meet you.
