Software Engineer

Role Description

At The Flex, we believe renting a home should feel as effortless as booking a ride. Our mission is ambitious: enable anyone to live anywhere, anytime, without friction. We're looking for a highly ambitious engineer who wants to build systems that create leverage at scale. This isn't a role where you'll spend months debating specifications. You'll build, ship, automate, and solve real-world problems that directly impact thousands of guests and properties.

What You'll Build

• Help architect and scale Base360.ai—the technology platform powering every aspect of The Flex.
• Build internal products, automation engines, AI-powered workflows, integrations, and operational systems.

Your Mission

• Build the Core Platform: Design and develop scalable applications, services, and APIs that power bookings, pricing, payments, guest experiences, and operations.
• Create Powerful Automations: Build event-driven workflows that automate tasks previously performed by humans.
• Develop AI-Powered Systems: Leverage LLMs, AI agents, and machine intelligence to streamline operations, improve decision-making, and enhance customer experiences.
• Design API-First Architecture: Create robust APIs that enable seamless communication between internal systems, third-party providers, and future products.
• Integrate the Ecosystem: Build and maintain integrations with platforms including Airbnb, Hostaway, Stripe, Twilio, OpenAI, Google, and other strategic partners.

  • Smart key management
