Rebuild the backbone of modern renting.
At The Flex, we believe renting a home should be instant, intelligent, and seamless — as easy as tapping a button.
Our ambition is bold: create a world where anyone can live anywhere without friction.
Powered by Base360.ai, our automation and intelligence platform, we’re building the operating system for global stays — syncing property data, orchestrating operations, and powering the infrastructure behind every effortless guest experience.
We’re hiring a Backend Engineer who loves building automation, scaling systems, and solving real-world problems with clean, resilient software.
What You’ll Build
As a Backend Engineer, you’ll architect the foundations of The Flex: the systems, APIs, and automation layers that coordinate global inventory, sync bookings in real time, and enable properties to operate autonomously.
Your work will blend digital automation with real-world logistics — enabling thousands of stays to run smoothly without manual intervention.
Your Mission
Build the Core — Design and scale robust APIs and backend services that manage bookings, payments, availability, and property intelligence.
Automate the Workflows — Develop serverless functions and microservices that eliminate repetitive tasks and streamline operations across cities and continents.
Connect the Ecosystem — Implement integrations between Base360.ai and major platforms such as Airbnb, Stripe, Twilio, and Hostaway.
Engineer for Scale — Architect event-driven systems and data pipelines capable of handling millions of events and transactions reliably.
Power Intelligence — Work with AI and data teams to embed smart automation and predictive logic into operational flows.
Collaborate Closely — Partner with product, front-end, and operations teams to translate messy real-world challenges into simple, scalable backend solutions.
You’ll Excel in This Role If You Have
Meaningful Impact — Your systems will become the automation engine of thousands of stays across multiple countries.
High Ownership — Small team, no bureaucracy, and the opportunity to influence core architectural decisions.
Speed & Autonomy — Move fast, ship often, and help define the future of our technical ecosystem.
Performance-Based Rewards — Competitive salary + meaningful equity opportunities for top performers.
Fully Remote — Work from anywhere. What matters is excellence, not timesheets.
