Backend Engineer – Full-time - Remote

Reinvent How The World Rents.

At The Flex , we believe renting a home should be as effortless as ordering an Uber.

Our mission : make renting borderless, instant, and intelligent. Through Base360.ai , our proprietary platform, we’re building the digital nervous system of the rental world — connecting property data, automating operations, and creating the intelligent infrastructure that powers every stay, everywhere.

We’re looking for a Backend Engineer who thrives on automation, scalability, and impact — someone who can turn complex real-world systems into elegant, self-sustaining software.

What You’ll Build

As a Backend Engineer, you’ll design and scale the backbone of The Flex — the APIs, automations, and intelligence layers that connect global booking platforms, power predictive insights, and orchestrate real-world logistics. Your work will bridge digital intelligence and physical operations — enabling thousands of seamless stays to happen automatically, without human intervention.

Your Mission

• Architect Core Systems – Build scalable, high-performance APIs and backend services that drive global bookings, payments, and property data synchronization.
• Automate Operations – Create microservices and serverless functions that remove repetitive manual processes and enhance efficiency.
• Integrate Intelligently – Connect Base360.ai with platforms like Airbnb, Stripe, Twilio, and Hostaway through robust, maintainable integrations.
• Design for Scale – Build fault-tolerant, event-driven systems and data pipelines capable of handling millions of transactions across borders.
• Enhance Intelligence – Collaborate with AI and data teams to embed predictive automation into operational workflows.
• Collaborate for Impact – Partner with product, operations, and front-end teams to turn complex real-world challenges into clean, scalable backend solutions.
