Job description
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. As a Senior Software Engineer, you’ll design, build, and scale critical parts of The Flex platform — from core services and APIs to automation workflows and real-time systems. You’ll operate with high autonomy, owning problems end-to-end and contributing directly to architectural decisions, while staying deeply hands-on with production code. Your Mission: - Build Core Systems: Develop and maintain scalable services that power bookings, payments, availability, pricing, and guest experience. - Design Robust APIs: Create clean, well-structured APIs that connect Base360.ai with internal tools and external partners. - Automate Operations: Build event-driven workflows that eliminate manual processes and unlock operational leverage. - Ship with Confidence: Deploy and operate cloud-native infrastructure on AWS with a focus on reliability, security, and performance. - Solve Meaningful Problems: Work on real-time booking synchronization, pricing intelligence, keyless access logic, AI-powered alerts, and live operational dashboards. - Collaborate for Impact: Work closely with product, data, and operations teams to turn complex requirements into simple, effective systems.
Requirements
- Strong experience building production systems with Node.js, React, and AWS - A solid understanding of distributed systems and API-first design - Experience with Python / FastAPI for automation or data services (bonus) - A track record of shipping clean, maintainable, scalable code - Comfort owning features and systems from design to production - Curiosity about automation, AI-driven operations, and proptech - A bias toward execution — you deliver, iterate, and improve continuously
