Senior Full-Stack Product Engineer

About Us Base360.ai is the AI operating system for short-term rental businesses, helping property managers run their operations on autopilot. Born out of The Flex, a short-term rental operator that scaled to an eight-figure business using its own software, Base360.ai is now launching as a standalone platform for short-term rental operators worldwide. We bring reservations, guest communication, pricing, payments, cleaning, maintenance, and reporting into one platform—helping operators automate manual work, reduce costs, increase revenue, and scale their portfolios. We're looking for an ambitious Senior Full-Stack Product Engineer who wants to turn real customer problems into intuitive, reliable software. You'll work closely with founders, designers, and operators to identify what matters, build solutions, and improve them based on how people use them. If you enjoy owning the full journey from customer problem to shipped product—and you're excited by AI, automation, and short-term rentals—we want to meet you. What You'll Build As a Senior Full-Stack Product Engineer, you'll help shape and scale Base360.ai across the entire short-term rental lifecycle. You'll build customer-facing features, operational dashboards, automation engines, AI-powered workflows, and integrations that help property managers grow without increasing their workload at the same rate. Your work will connect what users see with the systems behind it—from a guest’s check-in experience to the workflows coordinating reservations, cleaning, payments, and owner reporting. Your Mission Understand Customer Problems Work directly with property managers and internal teams to understand their workflows, identify friction, and decide which problems are worth solving. Build Products End-to-End Take features from idea and prototype through frontend, backend, integrations, testing, and deployment. Own the complete experience and how it performs in production. Create Intuitive User Experiences Work with designers to make complex short-term rental operations easy to manage. Build interfaces that help users complete tasks quickly and confidently. Create Powerful Automations Build event-driven workflows that eliminate repetitive work—from scheduling cleaning after a booking to sending check-in instructions and generating owner statements. Develop AI-Powered Features Use LLMs and AI agents to automate guest communication, triage maintenance requests, support pricing decisions, and help operators manage their portfolios more efficiently. Connect the Ecosystem Build reliable APIs and integrations with platforms including Airbnb, Hostaway, Stripe, Twilio, OpenAI, Google, and other partners across the short-term rental ecosystem.

Improve features based on adoption, time saved, fewer errors, and better user outcomes. Build for Scale Make sound technical decisions that balance delivery speed, maintainability, security, and reliability as more operators and properties join the platform.
