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. 🧠 **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. 🚫 **Do Not Apply If** * You’re looking for a slow, predictable 9–5\. * You prefer meetings over momentum. * You’re satisfied with average code and average results. * You’re not striving to operate in the top 1% of your craft.
