Reinvent How The World Rents.

  • At The Flex, we believe renting a home should feel as effortless as ordering an Uber.
  • Our mission is to 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 an 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 operational 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 channels, automate real-world logistics, and power predictive insights across cities.

Your work will make the difference between chaos and flow — enabling thousands of stays to happen seamlessly, without human intervention.

⚙️ Your Mission

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

🧠 You’Re A Great Fit If You Have

  • Strong skills in Node.js, Python (FastAPI), and AWS (serverless stack preferred).
  • Experience designing and scaling API-first architectures.
  • Deep understanding of databases, data synchronization, and event-driven systems.
  • Curiosity about automation, real estate tech, and AI-powered operations.
  • A “systems thinker” mindset — building for resilience, not just function.
  • A bias for action, and comfort working in a fast-moving, high-accountability environment.
