  • Build integrations with platforms such as Airbnb, Stripe, Hostaway, Twilio, Google, and OpenAI.

  • AI-powered workflows have been deployed across the business
  • Base360.ai has become a stronger competitive advantage for The Flex

  • Your work will impact thousands of users and properties across multiple countries.
  • You'll work closely with founders and gain exposure to engineering, product, operations, AI, and business.
  • Work from anywhere.
  • We're building quickly and looking for people who want to grow alongside the company.
  • You prefer highly structured corporate environments
  • You only want to write code from predefined specifications
  • You avoid ownership outside your immediate responsibilities
