Full Stack Developer
Join to apply for the Full Stack Developer role at The Flex.
Join the team redefining the future of global living. At The Flex, we believe renting a home should feel instant, intelligent, and effortless — just like booking a ride. Our vision is ambitious: a world where people can live anywhere, anytime, without friction. Powered by Base360.ai, our proprietary automation engine, we’re creating the operating system for the modern rental ecosystem. We connect property data, orchestrate operations, and build an intelligent layer that powers seamless stays across continents. If you’re an engineer excited by automation, AI, and large‑scale real‑world systems, this is your opportunity to help reshape how millions move, live, and experience the world.
What You’ll Build
As a Full Stack Engineer, you’ll design and scale the technology behind The Flex — powering instant bookings, smart access, automated processes, and predictive operations. You’ll work across front‑end, backend, and cloud infrastructure, transforming complex operational problems into elegant, scalable solutions. You won’t just build features — you’ll create leverage, engineer automation, and lay the foundation for the intelligent rental infrastructure of tomorrow.
Your Mission
* Build the Engine – Create fast, reliable, and scalable web applications that run core processes like bookings, payments, availability, and guest experience.
* Automate at Scale – Build microservices and AI‑powered workflows that reduce manual work across the entire business.
* Connect the Ecosystem – Architect powerful integrations between Base360.ai and platforms like Airbnb, Stripe, Hostaway, and Twilio.
* Launch & Iterate Fast – Deploy and manage serverless cloud infrastructure (AWS) with an obsession for speed, reliability, and global scale.
* Solve Hard Problems – Work on real‑time booking sync, pricing intelligence, keyless access logic, and live operational dashboards.
* Build With the Team – Work closely with product, data, and operations to bring automation from idea → code → impact.
You’re a Great Fit If You Have
* Strong experience with Node.js, React, and AWS (especially serverless).
* A deep understanding of API‑first architectures and distributed systems.
* Experience with Python/FastAPI for automation, scripting, or data services (bonus).
* A reputation for building clean, scalable, production‑ready systems.
* Curiosity about automation, real estate technology, and AI‑driven operations.
* A bias toward execution — you ship fast, learn quickly, and love solving complex problems.
Why You’ll Love Working Here
* Build Real Impact – Your code will directly shape the experience of thousands of stays and help modernize a multi‑trillion‑dollar industry.
* Small Team, Big Mission – High ownership, zero bureaucracy, and the chance to build foundational systems.
* Learning & Growth – We move fast, iterate constantly, and improve through feedback.
* Performance‑Based Rewards – Competitive compensation + meaningful upside for exceptional talent.
* Remote‑First – Work from anywhere. We trust you to deliver outcomes, not fill hours.
This Role Is Not for You If
* You want a slow, stable 9–5.
* You prefer planning over building.
* You’re satisfied being average.
* You’re not driven to become elite in your craft.
