Backend Developer

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.

• Strong experience building and scaling API-first products.
• A deep understanding of databases, synchronization logic, and distributed systems.
• A passion for automation, intelligent operations, and emerging PropTech.
• A systems-level mindset — you think in terms of resilience, reliability, and flow.
• A strong bias toward execution and ownership.
