ai is the AI operating system for short-term rental businesses, helping property managers run their operations on autopilot.
Born out of The Flex, a short-term rental operator that scaled to an eight-figure business using its own software, Base360.ai 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 an ambitious Product Engineer who wants to turn real customer problems into intuitive, reliable software. If you enjoy owning the full journey from customer problem to shipped product—and you’re excited by AI, automation, and short-term rentals—we want to meet you.
As a Product Engineer, you’ll help shape and scale Base360.ai across the entire short-term rental lifecycle.
Your work will connect what users see with the systems behind it—from a guest’s check-in experience to the workflows coordinating reservations, cleaning, payments,



and owner reporting.
Take features from idea and prototype through frontend, backend, integrations, testing, and deployment. Own the complete experience and how it performs in production.
CREATE INTUITIVE USER EXPERIENCES
Work with designers to make complex short-term rental operations easy to manage. Build event-driven workflows that eliminate repetitive work—from scheduling cleaning after a booking to sending check-in instructions and generating owner statements.
Build reliable APIs and integrations with platforms including Airbnb, Hostaway, Stripe, Twilio, OpenAI, Google, and other partners across the short-term rental ecosystem.
