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.
🧠 You’re a Great Fit If You Have
Strong experience with Node.js, Python (FastAPI), and AWS (serverless stack preferred).
Proven track record designing and scaling API-first architectures.
Deep understanding of databases, data synchronization, and event-driven systems.
Curiosity for automation, AI, and real estate technology.
A systems thinker mindset — you design for resilience, not just function.
A bias for action — you thrive in fast-moving, high-accountability environments.
🌍 Why You’ll Love It Here
Massive Impact – Your systems will power thousands of stays and automate the backbone of a $4T global industry.
Global Mission, Lean Team – No bureaucracy. No silos. Just high performers moving fast.
Autonomy & Growth – Own projects end-to-end and shape our technical roadmap.
Performance-Driven Rewards – Competitive compensation and meaningful upside for top contributors.
Remote-First Culture – Work from anywhere. We care about output, not office hours.
