[Hiring] Senior Full-Stack Product Engineer @The Flex

Role Description

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.
• Solve Real Operational Problems: Build solutions for:
  • Real-time reservation and availability synchronization
  • Dynamic pricing intelligence
  • Smart lock access and key management
  • Automated guest communication across channels
  • Guest check-in and upsell journeys
  • Operational forecasting
  • Cleaning and maintenance automation
  • Owner reporting and financial workflows
  • AI-powered monitoring and alerts
• Measure and Improve: Use customer feedback, product usage, and operational results to evaluate what you ship. 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.

Qualifications

• Strong experience building and shipping production software
• The ability to work across frontend and backend systems
• Experience with React, TypeScript, Python, FastAPI, or similar technologies
• Strong understanding of APIs, databases, integrations, and cloud architecture
• A product mindset and curiosity about why users need a feature
• Good judgment around usability, scope, and technical trade-offs
• The ability to turn an ambiguous problem into a practical, working solution
• Confidence working directly with customers, designers, and founders
• The ability to work independently and own outcomes
• Curiosity about AI, automation, and operational efficiency
• A bias toward shipping, learning, and iterating

Bonus Points

• Experience with short-term rentals, hospitality technology, or property management systems
• Multi-tenant SaaS platforms
• Marketplace businesses and booking channel integrations
• AI agents and workflow automation
• Product analytics and experimentation
• Event-driven architectures
• Supabase
• AWS serverless infrastructure

What Success Looks Like

• You've shipped features that property managers actively use
• Core short-term rental workflows are automated through products you've built
• Customers spend less time on manual administration and repetitive tasks
• Complex workflows become easier to understand and complete
• Integrations move reservations, availability, payments, and operational data reliably
• AI-powered features become part of customers’ everyday operations
• Customer feedback and usage data consistently inform your product decisions
• Your work helps operators grow their portfolios, improve guest experiences, and operate more profitably

Why Join Us

• Build Something Meaningful: Solve problems experienced daily by short-term rental operators, with direct access to The Flex’s operations to test ideas and see their impact.
• Own the Product Outcome: Help decide what to build, how it should work, and how to measure its success. Take responsibility for features from the first conversation through ongoing improvement.
• Small Team, Massive Opportunity: Work closely with the founders and directly influence the product and technical direction of Base360.ai.
• Learn Faster: Solve real-world challenges across product, software, AI, automation, hospitality operations, and scale.
• Performance-Based Rewards: Competitive compensation with substantial upside for exceptional performers.
• Remote-First: Work from anywhere. We care about outcomes, not hours.

This Role Is Not For You If

• You're looking for a slow-paced corporate environment
• You want a narrowly defined role with limited customer or product involvement
• You need detailed specifications before you can make progress
• You avoid ownership and accountability
• You consider a feature finished without checking whether it solves the user’s problem
