Lead Full-Stack Engineer

oin the team redefining the future of global living. At **The Flex** , we believe renting a home should feel instant, intelligent, and effortless — as seamless as booking a ride. Our ambition is bold: enabling anyone to live anywhere, anytime, without friction. Powered by **Base360\.ai** , our proprietary automation engine, we’re building the operating system for modern renting — connecting property data, orchestrating operations, and enabling seamless stays across continents. If you’re driven by **technical ownership, system architecture, and building platforms that operate at real\-world scale** , this role puts you at the center of how millions of people move, live, and experience the world. 💡 What You’ll Build As a **Lead Full\-Stack Engineer** , you will own the architecture and technical direction of The Flex platform — spanning web applications, APIs, automation engines, and cloud infrastructure. You’ll lead by building. You’ll design systems, set standards, and make key technical decisions while remaining deeply hands\-on across the stack. This is not a people\-management role. It’s a **technical leadership role** for someone who wants to shape systems, mentor by example, and build platforms that scale globally. ⚙️ Your Mission **Own the Architecture** Define and evolve the technical architecture powering bookings, payments, availability, pricing, and guest experience. **Lead by Building** Deliver critical features end\-to\-end across frontend, backend, and infrastructure — setting the bar for quality and speed. **Design API\-First Platforms** Architect scalable, well\-structured APIs that connect Base360\.ai to internal tools and external partners. **Automate the Business** Build event\-driven services and intelligent workflows that replace manual operations across the company. **Integrate at Scale** Own and evolve deep integrations with platforms such as Airbnb, Stripe, Hostaway, and Twilio. **Ship with Confidence** Deploy and operate serverless infrastructure on AWS, ensuring reliability, security, and global performance. **Solve the Hard Stuff** Lead solutions for real\-time booking sync, pricing intelligence, keyless access logic, AI\-powered alerts, and live operational dashboards. **Raise the Bar** Establish best practices, review critical code, and mentor engineers through example and technical clarity. 🧠 You’re a Great Fit If You Have * Strong senior\-level experience with Node.js, React, and AWS (serverless) * Proven ownership of system architecture and complex distributed systems * Deep experience designing and scaling API\-first platforms * Experience with Python / FastAPI for automation or data services (bonus) * A history of building production\-grade systems used at real scale * High standards for code quality, reliability, and performance * A builder’s mindset — you execute fast, think long\-term, and enjoy responsibility 🌍 Why You’ll Love Working Here **Architect Real Impact** Your decisions will shape a platform used across cities and continents. **High Ownership, No Politics** Small, elite team with real autonomy and zero corporate drag. **Build From First Principles** You’ll help define not just features, but the foundation of the company’s technology. **Performance\-Based Rewards** Top\-of\-market compensation with meaningful upside for exceptional leaders. **Remote\-First** Work from anywhere — we care about leverage and outcomes, not hours. 🚫 This Role Is Not for You If * You want a management\-heavy role with little hands\-on work * You avoid making hard technical decisions * You’re uncomfortable owning systems end\-to\-end * “Good enough” is acceptable to you
